Subject: [PATCH v3 3/9] arm64/debug: Eliminate magic number from ESR template definition
Date: Fri, 24 Jul 2015 16:37:43 +0100	[thread overview]
Message-ID: <1437752284-14847-4-git-send-email-Dave.Martin@arm.com> (raw)
In-Reply-To: <1437752284-14847-1-git-send-email-Dave.Martin@arm.com>

<asm/esr.h> has perfectly good constants for defining ESR values
already.  Let's use them.
