Subject: [GIT PULL 01/12] arm/arm64: KVM: Don't clear the VCPU_POWER_OFF flag
Date: Mon, 15 Dec 2014 12:41:48 +0100 [thread overview]
Message-ID: <1418643719-25966-2-git-send-email-christoffer.dall@linaro.org> (raw)
In-Reply-To: <1418643719-25966-1-git-send-email-christoffer.dall@linaro.org>
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.
