3.14-stable review patch. If anyone has any objections, please let me know.

From: Christoffer Dall <christoffer.dall@linaro.org>
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.
