1552 SMTC pseudo-interrupts between TCs are deferred and queued
1553 if the target TC is interrupt-inhibited (IXMT). In the first
1554 SMTC prototypes, these queued IPIs were serviced on return
1555 to user mode, or on entry into the kernel idle loop. The
1556 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1557 processing, which adds runtime overhead (hence the option to turn
1558 it off), but ensures that IPIs are handled promptly even under
1559 heavy I/O interrupt load.

1934 help
1935 kexec is a system call that implements the ability to shutdown your
1936 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +02001937 but it is independent of the system firmware. And like a reboot
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09001938 you can start any kernel with it, not just Linux.
1939
Matt LaPlante01dd2fb2007-10-20 01:34:40 +02001940 The name comes from the similarity to the exec system call.
Atsushi Nemotoea6e9422007-01-16 23:29:11 +09001941
1942 It is an ongoing process to be certain the hardware in a machine
1943 is properly shutdown, so do not be surprised if this code does not
1944 initially work for you. It may help to enable device hotplugging
1945 support. As of this writing the exact hardware interface is
1946 strongly in flux, so no good recommendation can be made.

1953 This kernel feature is useful for number crunching applications
1954 that may need to compute untrusted bytecode during their
1955 execution. By using pipes or other transports made available to
1956 the process as file descriptors supporting the read/write
1957 syscalls, it's possible to isolate those applications in
1958 their own address space using seccomp. Once seccomp is
1959 enabled via /proc/<pid>/seccomp, it cannot be disabled
1960 and the task is only allowed to execute a few safe syscalls
1961 defined by each seccomp mode.
