Subject: x86: define _PAGE_NUMA by reusing software bits on the PMD and PTE levels -fix
PowerPC has NUMA_BALANCING and non-NUMA_BALANCING versions of pte_present
and I missed that when testing cross-compiling. This should be collapsed
with the patch
x86-define-_page_numa-by-reusing-software-bits-on-the-pmd-and-pte-levels.patch
