Subject: [PATCH 19/23] x86, gcc-4.6: Use gcc -m options when building vdso
Date: Mon, 07 Feb 2011 00:23:11 +0100	[thread overview]
Message-ID: <20110206232253.336029706@pcw.home.local> (raw)
In-Reply-To: <4beed4da27f06efb2c13d6ed48850634@local>

2.6.27.58-stable review patch.  If anyone has any objections, please let us know.

------------------

From: H. Peter Anvin <hpa@linux.intel.com>

commit de2a8cf98ecdde25231d6c5e7901e2cffaf32af9 upstream.

The vdso Makefile passes linker-style -m options not to the linker but
to gcc.  This happens to work with earlier gcc, but fails with gcc
4.6.  Pass gcc-style -m options, instead.

Note: all currently supported versions of gcc supports -m32, so there
is no reason to conditionalize it any more.
