Subject: [PATCH 08/14] x86, boot: use BP_scratch in arch/x86/boot/compressed/head_*.S
Date: Thu,  7 May 2009 15:26:56 -0700	[thread overview]
Message-ID: <1241735222-6640-9-git-send-email-hpa@linux.intel.com> (raw)
In-Reply-To: <1241735222-6640-1-git-send-email-hpa@linux.intel.com>

From: H. Peter Anvin <hpa@zytor.com>

Use the BP_scratch symbol from asm-offsets.h instead of hard-coding
the location.

[ Impact: cleanup ]
