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.
