Subject: [PATCH 4/6] arm64: sysreg: Add some field definitions for PAR_EL1
Date: Tue, 27 Aug 2019 14:18:16 +0100	[thread overview]
Message-ID: <20190827131818.14724-5-will@kernel.org> (raw)
In-Reply-To: <20190827131818.14724-1-will@kernel.org>

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').
