Subject: [PATCH v2 3/3] arm64: Allow 48-bits VA space without ARM_SMMU
Date: Mon,  6 Oct 2014 22:30:27 +0200	[thread overview]
Message-ID: <1412627427-28629-4-git-send-email-christoffer.dall@linaro.org> (raw)
In-Reply-To: <1412627427-28629-1-git-send-email-christoffer.dall@linaro.org>

Now when KVM has been reworked to support 48-bits host VA space, we can
allow systems to be configured with this option.  However, the ARM SMMU
driver also needs to be tweaked for 48-bit support so only allow the
config option to be set when not including support for theSMMU.
