From e8620cff99946ea1f7891d7bec071a23a1fdaef3 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Thu, 22 Aug 2019 17:19:17 +0100 Subject: [PATCH] arm64: sysreg: Add some field definitions for PAR_EL1 PAR_EL1 is a mysterious creature, but sometimes it's necessary to read it when translating addresses in situations where we cannot walk the page table directly. Add a couple of system register definitions for the fault indication field ('F') and the fault status code ('FST').
