Subject: [RFC PATCH 07/13] arm64: kvm: add SYS_DESC()
Date: Tue, 31 Jan 2017 18:05:45 +0000 [thread overview]
Message-ID: <1485885951-2747-8-git-send-email-mark.rutland@arm.com> (raw)
In-Reply-To: <1485885951-2747-1-git-send-email-mark.rutland@arm.com>
This patch adds a macro enabling us to initialise sys_reg_desc
structures based on common sysreg encoding definitions in
<asm/sysreg.h>. Subsequent patches will use this to simplify the KVM
code.
