| Subject: selftests/powerpc: Make using_hash_mmu() work on Cell & PowerMac |
| |
| From: Michael Ellerman <mpe@ellerman.id.au> |
| |
| [ Upstream commit 34c103342be3f9397e656da7c5cc86e97b91f514 ] |
| |
| These platforms don't show the MMU in /proc/cpuinfo, but they always |
| use hash, so teach using_hash_mmu() that. |
