Subject: [PATCH 04/10] arm64/debug: Eliminate magic number from ESR template definition
Date: Thu, 11 Jun 2015 16:29:18 +0100 [thread overview]
Message-ID: <1434036566-9848-5-git-send-email-Dave.Martin@arm.com> (raw)
In-Reply-To: <1434036566-9848-1-git-send-email-Dave.Martin@arm.com>
<asm/esr.h> has perfectly good constants for defining ESR values
already. Let's use them.
