In more recent Linux kernels (including those with 47 bit VMAs) the layout of
virtual memory for powerpc64 changed causing the memory sanitizer to not
work properly. This patch adjusts a bit mask in the memory sanitizer to work
on the newer kernels while continuing to work on the older ones as well.
This is the non-runtime part of the patch and finishes it. ref: r317802
Tested on several 4.x and 3.x kernel releases.
