[Xen-devel] [PATCH v2 08/24] xen/arm: Add FnV field in hsr_*abt

2017-09-12 Thread Julien Grall
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 Gral
