#     mm, x86, powerpc: display pkey in smaps only if arch supports pkeys
#     
#     Currently the  architecture  specific code is expected to
#     display  the  protection  keys  in  smap  for a given vma.
#     This can lead to redundant code and possibly to divergent
#     formats in which the key gets displayed.
#     
#     This  patch  changes  the implementation. It displays the
#     pkey only if the architecture support pkeys, i.e
#     arch_pkeys_enabled() returns true.  This patch
#     provides x86 implementation for arch_pkeys_enabled().
#     
#     x86 arch_show_smap() function is not needed anymore.
#     Deleting it.
