[PATCH 0/2] KVM: arm/arm64: Guest synchronous halt/resume

[eric.auger@linaro.org (Eric Auger)]

This series introduces the capability to synchronously exit the guest
and prevent it from being re-entered.

This functionality is requested for IRQ forwarding where we need to make
sure the guest has exited and is prevented from being rescheduled until
we complete the forwarding state change.

This series does not introduce any user of the functionality. First user
will be IRQ forwarding. The split is done to ease the review process.

Best Regards
