According to the ACPI spec, the OSPM must ignore the contents of the
Processor Local APIC/SAPIC Affinity Structure in System Resource
Affinity Table (SRAT), if its enable flag is cleared. However, ia64
linux refers all of the Processor Local APIC/SAPIC Affinity Structures
in SRAT regardless of the enable flag. This is obviously against the
ACPI spec. This patch fixes this bug.

Quite a long time back, prepare_hugepage_range() replaced
is_aligned_hugepage_range() as the callback from mm/mmap.c to arch code to
verify if an address range is suitable for a hugepage mapping.
is_aligned_hugepage_range() stuck around, but only to implement
prepare_hugepage_range() on archs which didn't implement their own.

Most archs (everything except ia64 and powerpc) used the same
implementation of is_aligned_hugepage_range().  On powerpc, which
implements its own prepare_hugepage_range(), the custom version was never
used.

In addition, "is_aligned_hugepage_range()" was a bad name, because it
suggests it returns true iff the given range is a good hugepage range,
whereas in fact it returns 0-or-error (so the sense is reversed).

This patch cleans up by abolishing is_aligned_hugepage_range().  Instead
prepare_hugepage_range() is defined directly.  Most archs use the default
version, which simply checks the given region is aligned to the size of a
hugepage.  ia64 and powerpc define custom versions.  The ia64 one simply
checks that the range is in the correct address space region in addition to
being suitably aligned.  The powerpc version (just as previously) checks
for suitable addresses, and if necessary performs low-level MMU frobbing to
set up new areas for use by hugepages.

No libhugetlbfs testsuite regressions on ppc64 (POWER5 LPAR).

Remove the inlining of the new vs old mmap system call common code.  This

When on_each_cpu() runs the callback on other CPUs, it runs with local
interrupts disabled.  So we should run the function with local interrupts
disabled on this CPU, too.

And do the same for UP, so the callback is run in the same environment on both
UP and SMP.  (strictly it should do preempt_disable() too, but I think
local_irq_disable is sufficiently equivalent).

Also uninlines on_each_cpu().  softirq.c was the most appropriate file I could
find, but it doesn't seem to justify creating a new file.

Oh, and fix up that comment over (under?) x86's smp_call_function().  It

The AES setkey routine writes 64 bytes to the E_KEY area even though
there are only 60 bytes there.  It is in fact safe since E_KEY is
immediately follwed by D_KEY which is initialised afterwards.  However,
doing this may trigger undefined behaviour and makes Coverity unhappy.

So by combining E_KEY and D_KEY into one array we sidestep this issue
altogether.
