Subject: [PATCH v3 12/23] arm64: KVM: VHE: Use unified system register accessors
Date: Wed,  3 Feb 2016 18:00:05 +0000	[thread overview]
Message-ID: <1454522416-6874-13-git-send-email-marc.zyngier@arm.com> (raw)
In-Reply-To: <1454522416-6874-1-git-send-email-marc.zyngier@arm.com>

Use the recently introduced unified system register accessors for
those sysregs that behave differently depending on VHE being in
use or not.
