Delete all instances of asm/system.h as they should be redundant by this
point.

Split arch_align_stack() out from asm-generic/system.h into its own header of
asm-generic/exec.h as part of the asm/system.h disintegration.

Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h
to simplify disintegration of asm/system.h.

Make asm-generic/cmpxchg.h #include asm-generic/cmpxchg-local.h as all arch
files that #include the former also #include the latter. See:
grep -rl asm-generic/cmpxchg-local[.]h arch/ | sort > b
grep -rl asm-generic/cmpxchg[.]h arch/ | sort > a
comm a b
This simplifies the disintegration of asm-generic/system.h for arches that
don't have their own.

This header isn't exported to user-space, and even if it was, the
__KERNEL__ check covers the entire file, so we'd get a useless stub in the
first place. So punt it.

The version of cmpxchg defined in asm-generic/system.h does not handle
correctly non-long arguments. Use the version defined in cmpxchg.h
instead.

These are all kernel internal interfaces that get copied
around a lot. In most cases, architectures can provide
their own optimized versions, but these generic versions
can work as well.
I have tried to use the most common contents of each
header to allow existing architectures to migrate easily.
Thanks to Remis for suggesting a number of cleanups.
