[PATCH v1 0/3] KVM: arm64: Do not communicate host pmu event changes by accessing hyp data

[Fuad Tabba]

Hi,

This series changes the way KVM communicates host pmu event changes to the
hypervisor in nvhe and protected mode. Instead of accessing hyp data directly
from the host, the data is passed to hyp via the loaded vcpu. This gives more
isolation between the host and the hypervisor, and would allow us to use pmu in
protected mode.

This series is based on kvmarm/next.

Thanks,
