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:
