Subject: [GIT PULL] KVM/arm updates for Linux 5.3
Date: Tue, 9 Jul 2019 13:24:49 +0100 [thread overview]
Message-ID: <20190709122507.214494-1-marc.zyngier@arm.com> (raw)
Radim, Paolo,
This is the (slightly delayed) KVM/arm updates for 5.3. This time
around, some PMU emulation improvements, the ability to save/restore
the Spectre mitigation state, better SError handling that double as
the workaround for a N1 erratum, a 32bit fix for a corrupted MPIDR,
and yet another pre-NV cleanup.
Please pull,
M.
The following changes since commit 4b972a01a7da614b4796475f933094751a295a2f:
