Subject: selftests/powerpc: Make using_hash_mmu() work on Cell & PowerMac
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=34c103342be3f9397e656da7c5cc86e97b91f514;p=linux.git

selftests/powerpc: Make using_hash_mmu() work on Cell & PowerMac

These platforms don't show the MMU in /proc/cpuinfo, but they always
use hash, so teach using_hash_mmu() that.
