Subject: [PATCH 13/15] KVM: arm64: use common invariant sysreg definitions
Date: Thu, 9 Mar 2017 17:07:25 +0000 [thread overview]
Message-ID: <1489079247-31092-14-git-send-email-mark.rutland@arm.com> (raw)
In-Reply-To: <1489079247-31092-1-git-send-email-mark.rutland@arm.com>
Now that we have common definitions for the register encodings used by
KVM, make the KVM code uses thse for invariant sysreg definitions. This
makes said definitions a reasonable amount shorter, especially as many
comments are rendered redundant and can be removed.
