[Bug libc/6791] New: Add PROT_SAO define to mman.h to support Strong Access Ordering


This enhancement request is to add the define for PROT_SAO to powerpc/mman.h to
match the latest changes in the Linux kernel.  This define enables a new
hardware feature on Power7 to be used by applications to specify pages in a
process's address space that exhibit a stronger memory consistency model, Strong
Access Ordering.

The justification for the kernel change is in this changeset:

http://git.kernel.org/gitweb.cgi?p=linux/kernel/git/torvalds/
linux-2.6.git;a=commit;h=ef3d3246a0d06be622867d21af25f997aeeb105f

The change to powerpc/mman.h is
 here:
http://git.kernel.org/gitweb.cgi?p=linux/kernel/git/torvalds/
linux-2.
6.git;a=commitdiff;h=aba46c5027cb59d98052231b36efcbbde9c77a1d;hp=b845f313d78e4e259ec449909e3bbadf77b53a6d

This patch will create the PROT_SAO define in
libc/sysdeps/unix/sysv/linux/powerpc/bits/mman.h to match the linux kernel
header in powerpc/mman.h.
