Nick Piggin ce0ad7f095 powerpc/mm: Lockless get_user_pages_fast() for 64-bit (v3) ...

Implement lockless get_user_pages_fast for 64-bit powerpc.

Page table existence is guaranteed with RCU, and speculative page references
are used to take a reference to the pages without having a prior existence
guarantee on them.
