From a2dd4e83e76ba9c0d432145059dd9e2b2a096e2b Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Thu, 11 Apr 2019 10:00:01 +0200 Subject: ppc/hash64: Rework R and C bit updates With MT-TCG, we are now running translation in a racy way, thus we need to mimic hardware when it comes to updating the R and C bits, by doing byte stores. The current "store_hpte" abstraction is ill suited for this, we replace it with two separate callbacks for setting R and C.
