    Subject[PATCH 5.9 098/391] selftests/powerpc: Make using_hash_mmu() work on Cell & PowerMac
    Date
    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.
