Subject: [GIT PULL] KVM/arm64 fixes for 5.9, take #2
Date: Fri, 18 Sep 2020 18:16:49 +0100	[thread overview]
Message-ID: <20200918171651.1340445-1-maz@kernel.org> (raw)

Hi Paolo,

Here's the latest set of fixes for 5.9. The first patch is pretty
nasty, as a guest hitting this bug will have its vcpu stuck on a
fault, without any hope of it being resolved. Embarrassing, and
definitely a stable candidate. The second patch is only a cleanup
after the first one.

Please pull,

	M.
