From mboxrd@z Thu Jan 1 00:00:00 1970 From: will.deacon@arm.com (Will Deacon) Date: Wed, 24 Sep 2014 18:41:38 +0100 Subject: [PATCH v2] ARM: mm: clear SCTLR.HA instead of setting it for LPAE Message-ID: <1411580498-17367-1-git-send-email-will.deacon@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org SCTLR.HA (hardware access flag) is deprecated and not actually implemented by any CPUs. Furthermore, it can confuse cr_alignment checks where the whole value of SCTLR is compared against the value sitting in the hardware, since the bit is actually RAZ/WI and will not match the saved cr_alignment value.
