Subject: [PATCH 4.4 05/31] x86/asm: Add _ASM_ARG* constants for argument registers to <asm/asm.h>
Date: Fri, 20 Jul 2018 14:13:35 +0200 [thread overview]
Message-ID: <20180720121340.351022699__9600.2975981266$1532089577$gmane$org@linuxfoundation.org> (raw)
In-Reply-To: <20180720121340.158484922@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: H. Peter Anvin <hpa@linux.intel.com>
commit 0e2e160033283e20f688d8bad5b89460cc5bfcc4 upstream.
i386 and x86-64 uses different registers for arguments; make them
available so we don't have to #ifdef in the actual code.
Native size and specified size (q, l, w, b) versions are provided.
