Subject: [PATCH v4 04/14] ARM: KVM: __kvm_vcpu_run function return result fix in BE case
Date: Thu, 12 Jun 2014 09:30:03 -0700 [thread overview]
Message-ID: <1402590613-3341-5-git-send-email-victor.kamensky@linaro.org> (raw)
In-Reply-To: <1402590613-3341-1-git-send-email-victor.kamensky@linaro.org>
The __kvm_vcpu_run function returns a 64-bit result in two registers,
which has to be adjusted for BE case.
