Subject: [PATCH 0/2] KVM/arm64 fixes for 5.8, take #3
Date: Mon,  6 Jul 2020 12:05:19 +0100
Message-ID: <20200706110521.1615794-1-maz@kernel.org> (raw)

Hi Paolo,

Yet another small batch of fixes for 5.8. One is a long standing
preemption issue that got uncovered by another fix that went in
5.8. The other one is a fix for an issue potentially affecting kexec.

Please pull,

	M.
