This option can be used to specify one or more CPUs
to isolate from the general SMP balancing and scheduling
algorithms. The only way to move a process onto or off
an "isolated" CPU is via the CPU affinity syscalls.
This option is the preferred way to isolate CPUs. The
alternative - manually setting the CPU mask of all tasks
in the system can cause problems and suboptimal load
balancer performance.

* (C) Copyright 1996 Linus Torvalds

* Modified 1996-12-23 by Dave Grothe <dave@gcom.com> to fix bugs in
* the original code and to make semaphore waits
* interruptible so that processes waiting on
* semaphores can be killed.
* Modified 1999-02-14 by Andrea Arcangeli, split the sched.c helper
* functions in asm/sempahore-helper.h while fixing a
* potential and subtle race discovered by Ulrich Schmid
* in down_interruptible(). Since I started to play here I
* also implemented the `trylock' semaphore operation.
* 1999-07-02 Artur Skawina <skawina@geocities.com>
* Optimized "0(ecx)" -> "(ecx)" (the assembler does not
* do this). Changed calling sequences from push/jmp to
* traditional call/ret.
* Modified 2001-01-01 Andreas Franck <afranck@gmx.de>
* Some hacks to ensure compatibility with recent
* GCC snapshots, to avoid stack corruption when compiling
* with -fomit-frame-pointer. It's not sure if this will
* be fixed in GCC, as our previous implementation was a
* bit dubious.
*
* If you would like to see an analysis of this implementation, please
* ftp to gcom.com and download the file
* /pub/linux/src/semaphore/semaphore-2.0.24.tar.gz.
