Cover letter [PATCH/RFC 0/2] More Mempolicy Reference Counting Fixes

PATCH 0/2 Memory Policy: More Reference Counting Fixes

While testing huge pages using shm segments created with the SHM_HUGETLB flag, I came across additional problems with memory policy reference counting. While tracking these down, I found even more... Some of the problems were introduced by myself in my previous mempolicy ref counting patch, and some were paths that I missed in my inspection and testing.

These 2 patches are both based against 2.6.23-rc8-mm2, but should also probably go to the .23-stable tree when it opens. They have been tested on ia64 and x86_64 platforms.
