Will Deacon 88c0a794e5 arm64: mm: don't treat user cache maintenance faults as writes
commit db6f41063c upstream.

On arm64, cache maintenance faults appear as data aborts with the CM
bit set in the ESR. The WnR bit, usually used to distinguish between
faulting loads and stores, always reads as 1 and (slightly confusingly)
the instructions are treated as reads by the architecture.

This patch fixes our fault handling code to treat cache maintenance
faults in the same way as loads.
