Subject: [GIT PULL] KVM/arm64 fixes for 5.12, take #3
Date: Thu, 25 Mar 2021 11:44:30 +0000 [thread overview]
Message-ID: <20210325114430.940449-1-maz@kernel.org> (raw)
Hi Paolo,
Here's another set of fixes for KVM/arm64 in 5.12.
One patch fixes a GICv3 MMIO regression introduced when working around
a firmware bug. The last two patches prevent the guest from messing
with the ARMv8.4 tracing, a new feature that was introduced in 5.12.
Please pull,
M.
