I am not sure this is the right thing to do. I think we should keep
__GFP_NORETRY and clear it where we want a stronger semantic. This is
just too suble that all callsites are doing the right thing.
That would complicate alloc_hugepage_direct_gfpmask() a bit, but if you
think it's worth it, I can turn the default around, OK.
