Merge branch 'kvm-arm64/misc' into kvmarm/next
* kvm-arm64/misc:
: Miscellaneous fixes/cleanups for KVM/arm64
:
: - Avoid GICv4 vLPI configuration when confronted with user error
:
: - Only attempt vLPI configuration when the target routing is an MSI
:
: - Document ordering requirements to avoid aforementioned user error
KVM: arm64: Tear down vGIC on failed vCPU creation
KVM: arm64: Document ordering requirements for irqbypass
KVM: arm64: vgic-v4: Fall back to software irqbypass if LPI not found
KVM: arm64: vgic-v4: Only WARN for HW IRQ mismatch when unmapping vLPI
KVM: arm64: vgic-v4: Only attempt vLPI mapping for actual MSIs
