Subject: arm/arm64: KVM: Don't clear the VCPU_POWER_OFF flag

From: Christoffer Dall <[email protected]>

commit 03f1d4c17edb31b41b14ca3a749ae38d2dd6639d upstream.

If a VCPU was originally started with power off (typically to be brought up by PSCI in SMP configurations), there is no need to clear the POWER_OFF flag in the kernel, as this flag is only tested during the init ioctl itself.
