Merge branch 'usb-linus' into usb-next
This is to pick up the fixes in that branch, and let Alan fix the merge
error in drivers/usb/host/ehci-timer.c better than I just did (as I know
I messed it up...)

-Currently the ALPS touchpad driver supports four protocol versions in use by
-ALPS touchpads, called versions 1, 2, 3, and 4. Information about the various
-protocol versions is contained in the following sections.
+Since roughly mid-2010 several new ALPS touchpads have been released and
+integrated into a variety of laptops and netbooks. These new touchpads
+have enough behavior differences that the alps_model_data definition
+table, describing the properties of the different versions, is no longer
+adequate. The design choices were to re-define the alps_model_data
+table, with the risk of regression testing existing devices, or isolate
+the new devices outside of the alps_model_data table. The latter design
+choice was made. The new touchpad signatures are named: "Rushmore",
+"Pinnacle", and "Dolphin", which you will see in the alps.c code.
+For the purposes of this document, this group of ALPS touchpads will
+generically be called "new ALPS touchpads".
+
+We experimented with probing the ACPI interface _HID (Hardware ID)/_CID
+(Compatibility ID) definition as a way to uniquely identify the
+different ALPS variants but there did not appear to be a 1:1 mapping.
+In fact, it appeared to be an m:n mapping between the _HID and actual
+hardware type.

+ 3.3 Multiqueue tuntap interface:
+
+ From version 3.8, Linux supports multiqueue tuntap which can uses multiple
+ file descriptors (queues) to parallelize packets sending or receiving. The
+ device allocation is the same as before, and if user wants to create multiple
+ queues, TUNSETIFF with the same device name must be called many times with
+ IFF_MULTI_QUEUE flag.
+
+ char *dev should be the name of the device, queues is the number of queues to
+ be created, fds is used to store and return the file descriptors (queues)
+ created to the caller. Each file descriptor were served as the interface of a
+ queue which could be accessed by userspace.
+

+ #include <linux/if_tun.h>
+

+ * IFF_TAP - TAP device

+ * IFF_MULTI_QUEUE - Create a queue of multiqueue device

+
+ A new ioctl(TUNSETQUEUE) were introduced to enable or disable a queue. When

+ calling it with IFF_ATTACH_QUEUE flag, the queue were enabled. The queue were

- This option will modify all the calls to ftrace dynamically

+ This option will modify all the calls to function tracing
+ dynamically (will patch them out of the binary image and
+ replace them with a No-Op instruction) on boot up. During
+ compile time, a table is made of all the locations that ftrace
+ can function trace, and this table is linked into the kernel
+ image. When this is enabled, functions can be individually
+ enabled, and the functions not enabled will not affect
+ performance of the system.
+
+ See the files in /sys/kernel/debug/tracing:
+ available_filter_functions
+ set_ftrace_filter
+ set_ftrace_notrace
This way a CONFIG_FUNCTION_TRACER kernel is slightly larger, but
otherwise has native performance as long as no tracing is active.
- The changes to the code are done by a kernel thread that
- wakes up once a second and checks to see if any ftrace calls
- were made. If so, it runs stop_machine (stops all CPUS)
- and modifies the code to jump over the call to ftrace.
