Subject: [PATCH 0/2] KVM: arm: fix KVM_CAP_ARM_INJECT_EXT_DABT for aarch32 guests
Date: Tue, 21 Jan 2020 12:33:54 +0000	[thread overview]
Message-ID: <20200121123356.203000-1-james.morse@arm.com> (raw)

Beata reports that KVM_CAP_ARM_INJECT_EXT_DABT doesn't do the expected
thing for aarch32 guests. We get the wrong register layout, and weren't
even trying to set a 'external abort' in the first place!

Both patches are intended as fixes, but patch 2 is somewhat in the eye
of the beholder. I don't know why an imp-def exception was picked...

Thanks,

James Morse (2):
  KVM: arm: fix DFSR setting for non-LPAE aarch32 guests
  KVM: arm: Make inject_abt32() inject an external abort instead
