From mboxrd@z Thu Jan 1 00:00:00 1970 From: Dave.Martin@arm.com (Dave Martin) Date: Mon, 13 Jul 2015 14:25:50 +0100 Subject: [PATCH v2 03/10] arm64: esr.h type fixes and cleanup In-Reply-To: <1436793967-7138-1-git-send-email-Dave.Martin@arm.com> References: <1436793967-7138-1-git-send-email-Dave.Martin@arm.com> Message-ID: <1436793967-7138-4-git-send-email-Dave.Martin@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org ESR_ELx is a 32-bit register, so it is not necessary for all the template values defined by esr.h to be forced to 64-bit (long). This patch introduces a UINT() macro analogous to UL(), and applies it consistently. (Unfortunately, the more succinct U and UI names are already used in unrelated code, and cause conflicts since memory.h is widely included.) Since this change touches many lines already, I've taken the opportunity to squash some redundant parentheses and bogus whitespace at the same time. The missing include of (for UL(), UINT() etc.) is also added. No functional change.
