Subject: [RFC 07/17] KVM: arm: rename pause into power_off
Date: Thu,  2 Jul 2015 15:17:17 +0200	[thread overview]
Message-ID: <1435843047-6327-8-git-send-email-eric.auger@linaro.org> (raw)
In-Reply-To: <1435843047-6327-1-git-send-email-eric.auger@linaro.org>

The kvm_vcpu_arch pause field is renamed into power_off to prepare
for the introduction of a new pause field.

Signed-off-by: Eric Auger <eric.auger@linaro.org>

v4 -> v5:
- fix compilation issue on arm64 (add power_off field in kvm_host.h)
