Subject[PATCH v3 0/4] KVM: arm/arm64: guest synchronous halt/resume
This series introduces the capability to synchronously exit the guest
and prevent it from being re-entered. This modality will be used by
IRQ forwarding series when changing the state of the IRQ.

Former pause flag used when starting the vcpu in KVM_ARM_VCPU_POWER_OFF
state, in PSCI calls and in KVM_SET_MP_STATE ioctl is renamed into
power_off. A new pause flag is introduced. Both now are checked in
kvm_arch_vcpu_runnable and in the VCPU_RUN critical section, before
entering the vcpu.

Best Regards


v2 -> v3:
- unified the comment associated to the pause flag
- correct commit message of "KVM: arm/arm64: check power_off in
critical section before VCPU run"
- add Christoffer R-b on whole series

v1 -> v2:
- check pause, power_off and in kvm_arch_vcpu_runnable
- check power_off in vcpu_run critcal section before guest entry
- correct compil issue in first patch reported by Andrew
- rename vcpu_pause into vcpu_sleep

RFC -> PATCH v1:
- originally part of [RFC 00/17] ARM IRQ forward control based on IRQ
bypass manager ( and isolated in
this series.
- added __maybe_unused following Marc's advice
