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.
