Subject: [PATCH 3/8] x86 boot: x86_64 efi compiler warning fix
Date: Sun, 15 Jun 2008 23:29:56 -0700	[thread overview]
Message-ID: <20080616062956.14597.10460.sendpatchset@polaris-admin.engr.sgi.com> (raw)
In-Reply-To: <20080616062945.14597.78009.sendpatchset@polaris-admin.engr.sgi.com>

From: Paul Jackson <pj@sgi.com>

Fix a compiler warning.  Rather than always casting a u32 to a pointer
(which generates a warning on x86_64 systems) instead separate the
x86_32 and x86_64 assignments entirely with ifdefs.  Until other recent
changes to this code, it used to have x86_64 separated like this.
