Subject: [PATCH v2 08/24] xen/arm: Add FnV field in hsr_*abt
Date: Tue, 12 Sep 2017 11:03:14 +0100 [thread overview]
Message-ID: <20170912100330.2168-9-julien.grall@arm.com> (raw)
In-Reply-To: <20170912100330.2168-1-julien.grall@arm.com>
FnV (FAR not Valid) bit was introduced by ARMv8 in both AArch32 and
AArch64 (See D7-2275, D7-2277, G6-4958, G6-4962 in ARM DDI 0487B.a).
Note the new revision of ARMv8 defined more bits in HSR. They haven't
been added at the moment because we have no use of them in Xen.
Signed-off-by: Julien Grall <julien.grall@arm.com>
Reviewed-by: Andre Przywara <andre.przywara@arm.com>

Changes in v2:
- Expand the commit message to explain why the other bits have
not been added.
- Add Andre's reviewed-by
