Subject: [PATCH v2 02/17] ARM: KVM: Properly sort the invariant table
Date: Wed, 17 Feb 2016 16:40:34 +0000 [thread overview]
Message-ID: <1455727249-24752-3-git-send-email-marc.zyngier@arm.com> (raw)
In-Reply-To: <1455727249-24752-1-git-send-email-marc.zyngier@arm.com>
Not having the invariant table properly sorted is an oddity, and
may get in the way of future optimisations. Let's fix it.
