The Address Space Object
========================
-The address space object is used to identify pages in the page cache.
+The address space object is used to group and manage pages in the page
+cache. It can be used to keep track of the pages in a file (or
+anything else) and also track the mapping of sections of the file into
+process address spaces.
+There are a number of distinct yet related services that an
+address-space can provide. These include communicating memory
+pressure, page lookup by address, and keeping track of pages tagged as
+Dirty or Writeback.
+
+The first can be used independently to the others. The VM can try to
+either write dirty pages in order to clean them, or release clean
+pages in order to reuse them. To do this it can call the ->writepage
+method on dirty pages, and ->releasepage on clean pages with
+PagePrivate set. Clean pages without PagePrivate and with no external
+references will be released without notice being given to the
+address_space.
+
+To achieve this functionality, pages need to be placed on an LRU with
+lru_cache_add and mark_page_active needs to be called whenever the
+page is used.
+
+Pages are normally kept in a radix tree index by ->index. This tree
+maintains information about the PG_Dirty and PG_Writeback status of
+each page, so that pages with either of these flags can be found
+quickly.
+
+The Dirty tag is primarily used by mpage_writepages - the default
+->writepages method. It uses the tag to find dirty pages to call
+->writepage on. If mpage_writepages is not used (i.e. the address
+provides its own ->writepages) , the PAGECACHE_TAG_DIRTY tag is
+almost unused. write_inode_now and sync_inode do use it (through
+__sync_single_inode) to check if ->writepages has been successful in
+writing out the whole address_space.
+
+The Writeback tag is used by filemap*wait* and sync_page* functions,
+via wait_on_page_writeback_range, to wait for all writeback to
+complete. While waiting ->sync_page (if defined) will be called on
+each page that is found to require writeback.
+
+An address_space handler may attach extra information to a page,
+typically using the 'private' field in the 'struct page'. If such
+information is attached, the PG_Private flag should be set. This will
+cause various VM routines to make extra calls into the address_space
+handler to deal with that data.
+
+An address space acts as an intermediate between storage and
+application. Data is read into the address space a whole page at a
+time, and provided to the application either by copying of the page,
+or by memory-mapping the page.
+Data is written into the address space by the application, and then
+written-back to storage typically in whole pages, however the
+address_space has finer control of write sizes.
+
+The read process essentially only requires 'readpage'. The write
+process is more complicated and uses prepare_write/commit_write or
+set_page_dirty to write data into the address_space, and writepage,
+sync_page, and writepages to writeback data to storage.
+
+Adding and removing pages to/from an address_space is protected by the
+inode's i_mutex.
+
+When data is written to a page, the PG_Dirty flag should be set. It
+typically remains set until writepage asks for it to be written. This
+should clear PG_Dirty and set PG_Writeback. It can be actually
+written at any point after PG_Dirty is clear. Once it is known to be
+safe, PG_Writeback is cleared.
+
+Writeback makes use of a writeback_control structure...

+ other pages from the mapping if that is easier (e.g. due to
+ internal dependencies). If it chooses not to start writeout, it
+ should return AOP_WRITEPAGE_ACTIVATE so that the VM will not keep

+ If no ->writepages is given, then mpage_writepages is used

+ tagged as DIRTY and will pass them to ->writepage.
set_page_dirty: called by the VM to set a page dirty.
+ This is particularly needed if an address space attaches
+ private data to a page, and that data needs to be updated when
+ a page is dirtied. This is called, for example, when a memory

+ any basic-blocks on storage, then those blocks should be
+ pre-read (if they haven't been read already) so that the
+ updated blocks can be written out properly.
+ The page will be locked. If prepare_write wants to unlock the

+ a file, the file must have a stable mapping to a block
+ device. The swap system does not go through the filesystem
+ but instead uses bmap to find out where the blocks in the file
+ are and uses those addresses directly.
- invalidatepage: called by the VM on truncate to disassociate a page from its
- address_space mapping.
- releasepage: called by the VFS to release filesystem specific metadata from
- a page.
+ invalidatepage: If a page has PagePrivate set, then invalidatepage
+ will be called when part or all of the page is to be removed
+ from the address space. This generally corresponds to either a
+ truncation or a complete invalidation of the address space
+ (in the latter case 'offset' will always be 0).
+ Any private data associated with the page should be updated
+ to reflect this truncation. If offset is 0, then
+ the private data should be released, because the page
+ must be able to be completely discarded. This may be done by
+ calling the ->releasepage function, but in this case the
+ release MUST succeed.
- direct_IO: called by the VM for direct I/O writes and reads.
+ releasepage: releasepage is called on PagePrivate pages to indicate
+ that the page should be freed if possible. ->releasepage
+ should remove any private data from the page and clear the
+ PagePrivate flag. It may also remove the page from the
+ address_space. If this fails for some reason, it may indicate
+ failure with a 0 return value.
+ This is used in two distinct though related cases. The first
+ is when the VM finds a clean page with no active users and
+ wants to make it a free page. If ->releasepage succeeds, the
+ page will be removed from the address_space and become free.
+
+ The second case if when a request has been made to invalidate
+ some or all pages in an address_space. This can happen
+ through the fadvice(POSIX_FADV_DONTNEED) system call or by the
+ filesystem explicitly requesting it as nfs and 9fs do (when
+ they believe the cache may be out of date with storage) by
+ calling invalidate_inode_pages2().
+ If the filesystem makes such a call, and needs to be certain
+ that all pages are invalidated, then its releasepage will
+ need to ensure this. Possibly it can clear the PageUptodate
+ bit if it cannot free private data yet.
+
+ direct_IO: called by the generic read/write routines to perform
+ direct_IO - that is IO requests which bypass the page cache
+ and transfer data directly between the storage and the
+ application's address space.
get_xip_page: called by the VM to translate a block number to a page.
The page is valid until the corresponding filesystem is unmounted.
Filesystems that want to use execute-in-place (XIP) need to implement
it. An example implementation can be found in fs/ext2/xip.c.
+ migrate_page: This is used to compact the physical memory usage.
+ If the VM wants to relocate a page (maybe off a memory card
+ that is signalling imminent failure) it will pass a new page
+ and an old page to this function. migrate_page should
+ transfer any private data across and update any references
+ that it has to the page.

+ The syntax of the Module.symvers file is:
+ <CRC> <Symbol> <module>
+ Sample:
+ 0x2d036834 scsi_remove_host drivers/scsi/scsi_mod
+
+ For a kernel build without CONFIG_MODVERSIONING enabled the crc
+ would read: 0x00000000
+
+ Module.symvers serve two purposes.
+ 1) It list all exported symbols both from vmlinux and all modules
+ 2) It list CRC if CONFIG_MODVERSION is enabled
+
+--- 7.2 Symbols and external modules
+
+ When building an external module the build system needs access to
+ the symbols from the kernel to check if all external symbols are
+ defined. This is done in the MODPOST step and to obtain all
+ symbols modpost reads Module.symvers from the kernel.
+ If a Module.symvers file is present in the directory where
+ the external module is being build this file will be read too.
+ During the MODPOST step a new Module.symvers file will be written
+ containing all exported symbols that was not defined in the kernel.
+
+--- 7.3 Symbols from another external module
+
+ Sometimes one external module uses exported symbols from another
+ external module. Kbuild needs to have full knowledge on all symbols
+ to avoid spitting out warnings about undefined symbols.
+ Two solutions exist to let kbuild know all symbols of more than
+ one external module.
+ The method with a top-level kbuild file is recommended but may be
+ impractical in certain situations.
+
+ Use a top-level Kbuild file
+ If you have two modules: 'foo', 'bar' and 'foo' needs symbols
+ from 'bar' then one can use a common top-level kbuild file so
+ both modules are compiled in same build.
+
+ Consider following directory layout:
+ ./foo/ <= contains the foo module
+ ./bar/ <= contains the bar module
+ The top-level Kbuild file would then look like:
+
+ #./Kbuild: (this file may also be named Makefile)
+ obj-y := foo/ bar/
+
+ Executing:
+ make -C $KDIR M=`pwd`
+
+ will then do the expected and compile both modules with full
+ knowledge on symbols from both modules.
+
+ Use an extra Module.symvers file
+ When an external module is build a Module.symvers file is
+ generated containing all exported symbols which are not
+ defined in the kernel.
+ To get access to symbols from module 'bar' one can copy the
+ Module.symvers file from the compilation of the 'bar' module
+ to the directory where the 'foo' module is build.
+ During the module build kbuild will read the Module.symvers
+ file in the directory of the external module and when the
+ build is finished a new Module.symvers file is created
+ containing the sum of all symbols defined and not part of the
+ kernel.

+
+The robust futex ABI
+--------------------
+
+Robust_futexes provide a mechanism that is used in addition to normal
+futexes, for kernel assist of cleanup of held locks on task exit.
+
+The interesting data as to what futexes a thread is holding is kept on a
+linked list in user space, where it can be updated efficiently as locks
+are taken and dropped, without kernel intervention. The only additional
+kernel intervention required for robust_futexes above and beyond what is
+required for futexes is:
+
+ 1) a one time call, per thread, to tell the kernel where its list of
+ held robust_futexes begins, and
+ 2) internal kernel code at exit, to handle any listed locks held
+ by the exiting thread.
+
+The existing normal futexes already provide a "Fast Userspace Locking"
+mechanism, which handles uncontested locking without needing a system
+call, and handles contested locking by maintaining a list of waiting
+threads in the kernel. Options on the sys_futex(2) system call support
+waiting on a particular futex, and waking up the next waiter on a
+particular futex.
+
+For robust_futexes to work, the user code (typically in a library such
+as glibc linked with the application) has to manage and place the
+necessary list elements exactly as the kernel expects them. If it fails
+to do so, then improperly listed locks will not be cleaned up on exit,
+probably causing deadlock or other such failure of the other threads
+waiting on the same locks.
+
+A thread that anticipates possibly using robust_futexes should first
+issue the system call:
+
+ asmlinkage long
+ sys_set_robust_list(struct robust_list_head __user *head, size_t len);
+
+The pointer 'head' points to a structure in the threads address space
+consisting of three words. Each word is 32 bits on 32 bit arch's, or 64
+bits on 64 bit arch's, and local byte order. Each thread should have
+its own thread private 'head'.
+
+If a thread is running in 32 bit compatibility mode on a 64 native arch
+kernel, then it can actually have two such structures - one using 32 bit
+words for 32 bit compatibility mode, and one using 64 bit words for 64
+bit native mode. The kernel, if it is a 64 bit kernel supporting 32 bit
+compatibility mode, will attempt to process both lists on each task
+exit, if the corresponding sys_set_robust_list() call has been made to
+setup that list.
+
+ The first word in the memory structure at 'head' contains a
+ pointer to a single linked list of 'lock entries', one per lock,
+ as described below. If the list is empty, the pointer will point
+ to itself, 'head'. The last 'lock entry' points back to the 'head'.
+
+ The second word, called 'offset', specifies the offset from the
+ address of the associated 'lock entry', plus or minus, of what will
+ be called the 'lock word', from that 'lock entry'. The 'lock word'
+ is always a 32 bit word, unlike the other words above. The 'lock
+ word' holds 3 flag bits in the upper 3 bits, and the thread id (TID)
+ of the thread holding the lock in the bottom 29 bits. See further
+ below for a description of the flag bits.
+
+ The third word, called 'list_op_pending', contains transient copy of
+ the address of the 'lock entry', during list insertion and removal,
+ and is needed to correctly resolve races should a thread exit while
+ in the middle of a locking or unlocking operation.
+
+Each 'lock entry' on the single linked list starting at 'head' consists
+of just a single word, pointing to the next 'lock entry', or back to
+'head' if there are no more entries. In addition, nearby to each 'lock
+entry', at an offset from the 'lock entry' specified by the 'offset'
+word, is one 'lock word'.
+
+The 'lock word' is always 32 bits, and is intended to be the same 32 bit
+lock variable used by the futex mechanism, in conjunction with
+robust_futexes. The kernel will only be able to wakeup the next thread
+waiting for a lock on a threads exit if that next thread used the futex
+mechanism to register the address of that 'lock word' with the kernel.
+
+For each futex lock currently held by a thread, if it wants this
+robust_futex support for exit cleanup of that lock, it should have one
+'lock entry' on this list, with its associated 'lock word' at the
+specified 'offset'. Should a thread die while holding any such locks,
+the kernel will walk this list, mark any such locks with a bit
+indicating their holder died, and wakeup the next thread waiting for
+that lock using the futex mechanism.
+
+When a thread has invoked the above system call to indicate it
+anticipates using robust_futexes, the kernel stores the passed in 'head'
+pointer for that task. The task may retrieve that value later on by
+using the system call:
+
+ asmlinkage long
+ sys_get_robust_list(int pid, struct robust_list_head __user **head_ptr,
+ size_t __user *len_ptr);
+
+It is anticipated that threads will use robust_futexes embedded in
+larger, user level locking structures, one per lock. The kernel
+robust_futex mechanism doesn't care what else is in that structure, so
+long as the 'offset' to the 'lock word' is the same for all
+robust_futexes used by that thread. The thread should link those locks
+it currently holds using the 'lock entry' pointers. It may also have
+other links between the locks, such as the reverse side of a double
+linked list, but that doesn't matter to the kernel.
+
+By keeping its locks linked this way, on a list starting with a 'head'
+pointer known to the kernel, the kernel can provide to a thread the
+essential service available for robust_futexes, which is to help clean
+up locks held at the time of (a perhaps unexpectedly) exit.
+
+Actual locking and unlocking, during normal operations, is handled
+entirely by user level code in the contending threads, and by the
+existing futex mechanism to wait for, and wakeup, locks. The kernels
+only essential involvement in robust_futexes is to remember where the
+list 'head' is, and to walk the list on thread exit, handling locks
+still held by the departing thread, as described below.
+
+There may exist thousands of futex lock structures in a threads shared
+memory, on various data structures, at a given point in time. Only those
+lock structures for locks currently held by that thread should be on
+that thread's robust_futex linked lock list a given time.
+
+A given futex lock structure in a user shared memory region may be held
+at different times by any of the threads with access to that region. The
+thread currently holding such a lock, if any, is marked with the threads
+TID in the lower 29 bits of the 'lock word'.
+
+When adding or removing a lock from its list of held locks, in order for
+the kernel to correctly handle lock cleanup regardless of when the task
+exits (perhaps it gets an unexpected signal 9 in the middle of
+manipulating this list), the user code must observe the following
+protocol on 'lock entry' insertion and removal:
+
+On insertion:
+ 1) set the 'list_op_pending' word to the address of the 'lock word'
+ to be inserted,
+ 2) acquire the futex lock,
+ 3) add the lock entry, with its thread id (TID) in the bottom 29 bits
+ of the 'lock word', to the linked list starting at 'head', and
+ 4) clear the 'list_op_pending' word.
+
+On removal:
+ 1) set the 'list_op_pending' word to the address of the 'lock word'
+ to be removed,
+ 2) remove the lock entry for this lock from the 'head' list,
+ 2) release the futex lock, and
+ 2) clear the 'lock_op_pending' word.
+
+On exit, the kernel will consider the address stored in
+'list_op_pending' and the address of each 'lock word' found by walking
+the list starting at 'head'. For each such address, if the bottom 29
+bits of the 'lock word' at offset 'offset' from that address equals the
+exiting threads TID, then the kernel will do two things:
+
+ 1) if bit 31 (0x80000000) is set in that word, then attempt a futex
+ wakeup on that address, which will waken the next thread that has
+ used to the futex mechanism to wait on that address, and
+ 2) atomically set bit 30 (0x40000000) in the 'lock word'.
+
+In the above, bit 31 was set by futex waiters on that lock to indicate
+they were waiting, and bit 30 is set by the kernel to indicate that the
+lock owner died holding the lock.
+
+The kernel exit code will silently stop scanning the list further if at
+any point:
+
+ 1) the 'head' pointer or an subsequent linked list pointer
+ is not a valid address of a user space word
+ 2) the calculated location of the 'lock word' (address plus
+ 'offset') is not the valud address of a 32 bit user space
+ word
+ 3) if the list contains more than 1 million (subject to
+ future kernel configuration changes) elements.
+
+When the kernel sees a list entry whose 'lock word' doesn't have the
+current threads TID in the lower 29 bits, it does nothing with that
+entry, and goes on to the next entry.
+
+Bit 29 (0x20000000) of the 'lock word' is reserved for future use.

+
+Background
+----------
+
+what are robust futexes? To answer that, we first need to understand
+what futexes are: normal futexes are special types of locks that in the
+noncontended case can be acquired/released from userspace without having
+to enter the kernel.
+
+A futex is in essence a user-space address, e.g. a 32-bit lock variable
+field. If userspace notices contention (the lock is already owned and
+someone else wants to grab it too) then the lock is marked with a value
+that says "there's a waiter pending", and the sys_futex(FUTEX_WAIT)
+syscall is used to wait for the other guy to release it. The kernel
+creates a 'futex queue' internally, so that it can later on match up the
+waiter with the waker - without them having to know about each other.
+When the owner thread releases the futex, it notices (via the variable
+value) that there were waiter(s) pending, and does the
+sys_futex(FUTEX_WAKE) syscall to wake them up. Once all waiters have
+taken and released the lock, the futex is again back to 'uncontended'
+state, and there's no in-kernel state associated with it. The kernel
+completely forgets that there ever was a futex at that address. This
+method makes futexes very lightweight and scalable.
+
+"Robustness" is about dealing with crashes while holding a lock: if a
+process exits prematurely while holding a pthread_mutex_t lock that is
+also shared with some other process (e.g. yum segfaults while holding a
+pthread_mutex_t, or yum is kill -9-ed), then waiters for that lock need
+to be notified that the last owner of the lock exited in some irregular
+way.
+
+To solve such types of problems, "robust mutex" userspace APIs were
+created: pthread_mutex_lock() returns an error value if the owner exits
+prematurely - and the new owner can decide whether the data protected by
+the lock can be recovered safely.
+
+There is a big conceptual problem with futex based mutexes though: it is
+the kernel that destroys the owner task (e.g. due to a SEGFAULT), but
+the kernel cannot help with the cleanup: if there is no 'futex queue'
+(and in most cases there is none, futexes being fast lightweight locks)
+then the kernel has no information to clean up after the held lock!
+Userspace has no chance to clean up after the lock either - userspace is
+the one that crashes, so it has no opportunity to clean up. Catch-22.
+
+In practice, when e.g. yum is kill -9-ed (or segfaults), a system reboot
+is needed to release that futex based lock. This is one of the leading
+bugreports against yum.
+
+To solve this problem, the traditional approach was to extend the vma
+(virtual memory area descriptor) concept to have a notion of 'pending
+robust futexes attached to this area'. This approach requires 3 new
+syscall variants to sys_futex(): FUTEX_REGISTER, FUTEX_DEREGISTER and
+FUTEX_RECOVER. At do_exit() time, all vmas are searched to see whether
+they have a robust_head set. This approach has two fundamental problems
+left:
+
+ - it has quite complex locking and race scenarios. The vma-based
+ approach had been pending for years, but they are still not completely
+ reliable.
+
+ - they have to scan _every_ vma at sys_exit() time, per thread!
+
+The second disadvantage is a real killer: pthread_exit() takes around 1
+microsecond on Linux, but with thousands (or tens of thousands) of vmas
+every pthread_exit() takes a millisecond or more, also totally
+destroying the CPU's L1 and L2 caches!
+
+This is very much noticeable even for normal process sys_exit_group()
+calls: the kernel has to do the vma scanning unconditionally! (this is
+because the kernel has no knowledge about how many robust futexes there
+are to be cleaned up, because a robust futex might have been registered
+in another task, and the futex variable might have been simply mmap()-ed
+into this process's address space).
+
+This huge overhead forced the creation of CONFIG_FUTEX_ROBUST so that
+normal kernels can turn it off, but worse than that: the overhead makes
+robust futexes impractical for any type of generic Linux distribution.
+
+So something had to be done.
+
+New approach to robust futexes
+------------------------------
+
+At the heart of this new approach there is a per-thread private list of
+robust locks that userspace is holding (maintained by glibc) - which
+userspace list is registered with the kernel via a new syscall [this
+registration happens at most once per thread lifetime]. At do_exit()
+time, the kernel checks this user-space list: are there any robust futex
+locks to be cleaned up?
+
+In the common case, at do_exit() time, there is no list registered, so
+the cost of robust futexes is just a simple current->robust_list != NULL
+comparison. If the thread has registered a list, then normally the list
+is empty. If the thread/process crashed or terminated in some incorrect
+way then the list might be non-empty: in this case the kernel carefully
+walks the list [not trusting it], and marks all locks that are owned by
+this thread with the FUTEX_OWNER_DEAD bit, and wakes up one waiter (if
+any).
+
+The list is guaranteed to be private and per-thread at do_exit() time,
+so it can be accessed by the kernel in a lockless way.
+
+There is one race possible though: since adding to and removing from the
+list is done after the futex is acquired by glibc, there is a few
+instructions window for the thread (or process) to die there, leaving
+the futex hung. To protect against this possibility, userspace (glibc)
+also maintains a simple per-thread 'list_op_pending' field, to allow the
+kernel to clean up if the thread dies after acquiring the lock, but just
+before it could have added itself to the list. Glibc sets this
+list_op_pending field before it tries to acquire the futex, and clears
+it after the list-add (or list-remove) has finished.
+
+That's all that is needed - all the rest of robust-futex cleanup is done
+in userspace [just like with the previous patches].
+
+Ulrich Drepper has implemented the necessary glibc support for this new
+mechanism, which fully enables robust mutexes.
+
+Key differences of this userspace-list based approach, compared to the
+vma based method:
+
+ - it's much, much faster: at thread exit time, there's no need to loop
+ over every vma (!), which the VM-based method has to do. Only a very
+ simple 'is the list empty' op is done.
+
+ - no VM changes are needed - 'struct address_space' is left alone.
+
+ - no registration of individual locks is needed: robust mutexes dont
+ need any extra per-lock syscalls. Robust mutexes thus become a very
+ lightweight primitive - so they dont force the application designer
+ to do a hard choice between performance and robustness - robust
+ mutexes are just as fast.
+
+ - no per-lock kernel allocation happens.
+
+ - no resource limits are needed.
+
+ - no kernel-space recovery call (FUTEX_RECOVER) is needed.
+
+ - the implementation and the locking is "obvious", and there are no
+ interactions with the VM.
+
+Performance
+-----------
+
+I have benchmarked the time needed for the kernel to process a list of 1
+million (!) held locks, using the new method [on a 2GHz CPU]:
+
+ - with FUTEX_WAIT set [contended mutex]: 130 msecs
+ - without FUTEX_WAIT set [uncontended mutex]: 30 msecs
+
+I have also measured an approach where glibc does the lock notification
+[which it currently does for !pshared robust mutexes], and that took 256
+msecs - clearly slower, due to the 1 million FUTEX_WAKE syscalls
+userspace had to do.
+
+(1 million held locks are unheard of - we expect at most a handful of
+locks to be held at a time. Nevertheless it's nice to know that this
+approach scales nicely.)
+
+Implementation details
+----------------------
+
+The patch adds two new syscalls: one to register the userspace list, and
+one to query the registered list pointer:
+
+ asmlinkage long
+ sys_set_robust_list(struct robust_list_head __user *head,
+ size_t len);
+
+ asmlinkage long
+ sys_get_robust_list(int pid, struct robust_list_head __user **head_ptr,
+ size_t __user *len_ptr);
+
+List registration is very fast: the pointer is simply stored in
+current->robust_list. [Note that in the future, if robust futexes become
+widespread, we could extend sys_clone() to register a robust-list head
+for new threads, without the need of another syscall.]
+
+So there is virtually zero overhead for tasks not using robust futexes,
+and even for robust futex users, there is only one extra syscall per
+thread lifetime, and the cleanup operation, if it happens, is fast and
+straightforward. The kernel doesnt have any internal distinction between
+robust and normal futexes.
+
+If a futex is found to be held at exit time, the kernel sets the
+following bit of the futex word:
+
+ #define FUTEX_OWNER_DIED 0x40000000
+
+and wakes up the next futex waiter (if any). User-space does the rest of
+the cleanup.
+
+Otherwise, robust futexes are acquired by glibc by putting the TID into
+the futex field atomically. Waiters set the FUTEX_WAITERS bit:
+
+ #define FUTEX_WAITERS 0x80000000
+
+and the remaining bits are for the TID.
+
+Testing, architecture support
+-----------------------------
+
+i've tested the new syscalls on x86 and x86_64, and have made sure the
+parsing of the userspace list is robust [ ;-) ] even if the list is
+deliberately corrupted.
+
+i386 and x86_64 syscalls are wired up at the moment, and Ulrich has
+tested the new glibc code (on x86_64 and i386), and it works for his
+robust-mutex testcases.
+
+All other architectures should build just fine too - but they wont have
+the new syscalls yet.
+
+Architectures need to implement the new futex_atomic_cmpxchg_inatomic()
+inline function before writing up the syscalls (that function returns
+-ENOSYS right now).

-Except in cases of kmalloc failure, the lookup function
-will return a new datum which will store the key and

+ *
+ * The reasons for disabling some of the system calls are:
+ * 1. They interact with the way SPU syscalls are handled
+ * and we can't let them execute ever:
+ * restart_syscall, exit, for, execve, ptrace, ...
+ * 2. They are deprecated and replaced by other means:
+ * uselib, pciconfig_*, sysfs, ...
+ * 3. They are somewhat interacting with the system in a way
+ * we don't want an SPU to:
+ * reboot, init_module, mount, kexec_load
+ * 4. They are optional and we can't rely on them being
+ * linked into the kernel. Unfortunately, the cond_syscall
+ * helper does not work here as it does not add the necessary
+ * opd symbols:
+ * mbind, mq_open, ipc, ...

+ bool "Support adding drives to a raid-5 array (experimental)"
+ depends on MD_RAID5 && EXPERIMENTAL
+ ---help---
+ A RAID-5 set can be expanded by adding extra drives. This
+ requires "restriping" the array which means (almost) every
+ block must be written to a different place.
+
+ This option allows such restriping to be done while the array
+ is online. However it is still EXPERIMENTAL code. It should
+ work, but please be sure that you have backups.
+
+ You will need a version of mdadm newer than 2.3.1. During the
+ early stage of reshape there is a critical section where live data
+ is being over-written. A crash during this time needs extra care
+ for recovery. The newer mdadm takes a copy of the data in the
+ critical section and will restore it, if necessary, after a crash.
+
+ The mdadm usage is e.g.
+ mdadm --grow /dev/md1 --raid-disks=6
+ to grow '/dev/md1' to having 6 disks.
+
+ Note: The array can only be expanded, not contracted.
+ There should be enough spares already present to make the new
+ array workable.

+ 4 different qualities (no compression, low, medium, high).
+ It lists the bandwidth requirements for said mode by its alternate interface
+ number. An alternate of 0 means that the mode is unavailable.
+
+ There are 6 * 4 * 4 entries:
+ 6 different resolutions subqcif, qsif, qcif, sif, cif, vga
+ 6 framerates: 5, 10, 15, 20, 25, 30
+ 4 compression modi: none, low, medium, high
+
+ When an uncompressed mode is not available, the next available compressed mode
+ will be chosen (unless the decompressor is absent). Sometimes there are only
+ 1 or 2 compressed modes available; in that case entries are duplicated.

- *
- * mapbase is the physical address of the IO port. Currently, we don't
- * support this very well, and it may well be dropped from this driver
- * in future. As such, mapbase should be NULL.
- *
- * membase is an 'ioremapped' cookie. This is compatible with the old
- * serial.c driver, and is currently the preferred form.

- 4 different qualities (no compression, low, medium, high).
- It lists the bandwidth requirements for said mode by its alternate interface
- number. An alternate of 0 means that the mode is unavailable.
-
- There are 6 * 4 * 4 entries:
- 6 different resolutions subqcif, qsif, qcif, sif, cif, vga
- 6 framerates: 5, 10, 15, 20, 25, 30
- 4 compression modi: none, low, medium, high
-
- When an uncompressed mode is not available, the next available compressed mode
- will be chosen (unless the decompressor is absent). Sometimes there are only
- 1 or 2 compressed modes available; in that case entries are duplicated.

+config VGACON_SOFT_SCROLLBACK
+ bool "Enable Scrollback Buffer in System RAM"
+ depends on VGA_CONSOLE
+ default n
+ help
+ The scrollback buffer of the standard VGA console is located in
+ the VGA RAM. The size of this RAM is fixed and is quite small.
+ If you require a larger scrollback buffer, this can be placed in
+ System RAM which is dynamically allocated during intialization.
+ Placing the scrollback buffer in System RAM will slightly slow
+ down the console.
+
+ If you want this feature, say 'Y' here and enter the amount of
+ RAM to allocate for this buffer. If unsure, say 'N'.
+
+config VGACON_SOFT_SCROLLBACK_SIZE
+ int "Scrollback Buffer Size (in KB)"
+ depends on VGACON_SOFT_SCROLLBACK
+ default "64"

+ Enter the amount of System RAM to allocate for the scrollback
+ buffer. Each 64KB will give you approximately 16 80x25

+ * are not for detailed problem diagnosis, but simply to indicate that there
+ * is a problem.
+ *
+ * These counters are not meant to be human-readable, but are meant to be
+ * integrated into system monitoring tools such as "sar" and "iostat". As
+ * such, the counters are sampled by the tools over time, and are never
+ * zeroed after a file system is mounted. Moving averages can be computed
+ * by the tools by taking the difference between two instantaneous samples
+ * and dividing that by the time between the samples.

+ *
+ * 3. DIRECT - the number of bytes read or written from files opened

+ *
+ * These counters give a view of the data throughput into and out of the NFS

+ * number of bytes the client requests from the server can provide an
+ * indication of client efficiency (per-op, cache hits, etc).
+ *
+ * These counters can also help characterize which access methods are in
+ * use. DIRECT by itself shows whether there is any O_DIRECT traffic.
+ * NORMAL + DIRECT shows how much data is going through the system call
+ * interface. A large amount of SERVER traffic without much NORMAL or
+ * DIRECT traffic shows that applications are using mapped files.

- * just like a template in C++, this macro does cache lookup

- * The function is passed some sort of HANDLE from which a cache_detail
- * structure can be determined (via SETUP, DETAIL), a template
- * cache entry (type RTN*), and a "set" flag. Using the HASHFN and the
- * TEST, the function will try to find a matching cache entry in the cache.
- * If "set" == 0 :
- * If an entry is found, it is returned
- * If no entry is found, a new non-VALID entry is created.
- * If "set" == 1 and INPLACE == 0 :
- * If no entry is found a new one is inserted with data from "template"
- * If a non-CACHE_VALID entry is found, it is updated from template using UPDATE
- * If a CACHE_VALID entry is found, a new entry is swapped in with data
- * from "template"
- * If set == 1, and INPLACE == 1 :
- * As above, except that if a CACHE_VALID entry is found, we UPDATE in place
- * instead of swapping in a new entry.
- *
- * If the passed handle has the CACHE_NEGATIVE flag set, then UPDATE is not
- * run but insteead CACHE_NEGATIVE is set in any new item.
- * In any case, the new entry is returned with a reference count.
- *
- *
- * RTN is a struct type for a cache entry
- * MEMBER is the member of the cache which is cache_head, which must be first
- * FNAME is the name for the function
- * ARGS are arguments to function and must contain RTN *item, int set. May
- * also contain something to be usedby SETUP or DETAIL to find cache_detail.
- * SETUP locates the cache detail and makes it available as...
- * DETAIL identifies the cache detail, possibly set up by SETUP
- * HASHFN returns a hash value of the cache entry "item"
- * TEST tests if "tmp" matches "item"
- * INIT copies key information from "item" to "new"
- * UPDATE copies content information from "item" to "tmp"
- * INPLACE is true if updates can happen inplace rather than allocating a new structure
- *
- * WARNING: any substantial changes to this must be reflected in
- * net/sunrpc/svcauth.c(auth_domain_lookup)
- * which is a similar routine that is open-coded.

+/* msp3400 routing
+ ===============
+
+ The msp3400 has a complicated routing scheme with many possible
+ combinations. The details are all in the datasheets but I will try
+ to give a short description here.
+
+ Inputs
+ ======
+
+ There are 1) tuner inputs, 2) I2S inputs, 3) SCART inputs. You will have
+ to select which tuner input to use and which SCART input to use. The
+ selected tuner input, the selected SCART input and all I2S inputs go to
+ the DSP (the tuner input first goes through the demodulator).
+
+ The DSP handles things like volume, bass/treble, balance, and some chips
+ have support for surround sound. It has several outputs: MAIN, AUX, I2S
+ and SCART1/2. Each output can select which DSP input to use. So the MAIN
+ output can select the tuner input while at the same time the SCART1 output
+ uses the I2S input.
+
+ Outputs
+ =======
+
+ Most DSP outputs are also the outputs of the msp3400. However, the SCART
+ outputs of the msp3400 can select which input to use: either the SCART1 or
+ SCART2 output from the DSP, or the msp3400 SCART inputs, thus completely
+ bypassing the DSP.
+
+ Summary
+ =======
+
+ So to specify a complete routing scheme for the msp3400 you will have to
+ specify in the 'input' field of the v4l2_routing struct:
+
+ 1) which tuner input to use
+ 2) which SCART input to use
+ 3) which DSP input to use for each DSP output
+
+ And in the 'output' field of the v4l2_routing struct you specify:
+
+ 1) which SCART input to use for each SCART output
+
+ Depending on how the msp is wired to the other components you can
+ ignore or mute certain inputs or outputs.
+
+ Also, depending on the msp version only a subset of the inputs or
+ outputs may be present. At the end of this header some tables are
+ added containing a list of what is available for each msp version.
+ */
+
+/* Inputs to the DSP unit: two independent selections have to be made:
+ 1) the tuner (SIF) input
+ 2) the SCART input
+ Bits 0-2 are used for the SCART input select, bit 3 is used for the tuner
+ input, bits 4-7 are reserved.

+ The DSP outputs are: loudspeaker output (aka MAIN), headphones output
+ (aka AUX), SCART1 DA output, SCART2 DA output and an I2S output.
+ There also is a quasi-peak detector output, but that is not used by
+ this driver and is set to the same input as the loudspeaker output.
+ Not all outputs are supported by all msp models. Setting the input
+ of an unsupported output will be ignored by the driver.
+
+ There are up to 16 DSP inputs to choose from, so each output is
+ assigned 4 bits.
+
+ Note: the 44x8G can mix two inputs and feed the result back to the
+ DSP. This is currently not implemented. Also not implemented is the
+ multi-channel capable I2S3 input of the 44x0G. If someone can demonstrate
+ a need for one of those features then additional support can be added. */

depends on !MODULES || !(MIPS || PARISC || PPC || SUPERH || SPARC64 || V850)
- default DEBUG_KERNEL
help
If you say Y here the resulting kernel image will be slightly larger
but not slower, and it will give very useful debugging information.

/**************************************************
- * cache for domain name to auth_domain
- * Entries are only added by flavours which will normally
- * have a structure that 'inherits' from auth_domain.
- * e.g. when an IP -> domainname is given to auth_unix,
- * and the domain name doesn't exist, it will create a
- * auth_unix_domain and add it to this hash table.
- * If it finds the name does exist, but isn't AUTH_UNIX,
- * it will complain.
+ * 'auth_domains' are stored in a hash table indexed by name.
+ * When the last reference to an 'auth_domain' is dropped,
+ * the object is unhashed and freed.
+ * If auth_domain_lookup fails to find an entry, it will return
+ * it's second argument 'new'. If this is non-null, it will
+ * have been atomically linked into the table.
*/
-/*
- * Auth auth_domain cache is somewhat different to other caches,
- * largely because the entries are possibly of different types:
- * each auth flavour has it's own type.
- * One consequence of this that DefineCacheLookup cannot
- * allocate a new structure as it cannot know the size.
- * Notice that the "INIT" code fragment is quite different
- * from other caches. When auth_domain_lookup might be
- * creating a new domain, the new domain is passed in
- * complete and it is used as-is rather than being copied into
- * another structure.
