[v3,0/7] Rationalise __alloc_pages wrappers

Message

I was poking around the __alloc_pages variants trying to understand
why they each exist, and couldn't really find a good justification for
keeping __alloc_pages and __alloc_pages_nodemask as separate functions.
That led to getting rid of alloc_pages_current() and then I noticed the
documentation was bad, and then I noticed the mempolicy documentation
wasn't included ...
anyway, this is all cleanups & doc fixes.

v3:
 - Added acks from Mike (patches 5 & 7) & Michel (patch 5)
 - Improved wording of return value (Mike, patch 5)
 - Added patch 6
v2:
 - Added acks from Vlastimil (patches 2-4) & Michel (patches 3-4)
 - Added patches 1, 5 and 7
