I think we can also unify VM_MAPPED_COPY(nommu) and VM_SAO(powerpc)

Okay. After this series is merged, let's try to remove flags we can
do. Then, other guys
might suggest another ideas.
Agreed. I would like more VM_ARCH while at it :-)
Currently I see here four architecture-specific flags =)
VM_ARCH_1 VM_ARCH_2 VM_ARCH_3 VM_ARCH_4
x86 VM_NOHUGEPAGE VM_HUGEPAGE - VM_PFN_AT_MMAP
powerpc - - VM_SAO -
parisc VM_GROWSUP - - -
ia64 VM_GROWSUP - - -
nommu - VM_MAPPED_COPY - -
Obviously we can combine VM_PFN_AT_MMAP, VM_SAO, VM_GROWSUP and VM_MAPPED_COPY into one.
