Well, the GFP flags exist to avoid needing a gazillion of variants of
everything build around the page allocator.  For vmalloc we can't, as
Kent rightly said, support GFP_NOFS and GFP_NOIO and need to use the
scopes instead, and we should warn about that (which __vmalloc doesn't
and could use some fixes for).
