From de2a8cf98ecdde25231d6c5e7901e2cffaf32af9 Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Mon, 13 Dec 2010 16:01:38 -0800 Subject: [PATCH] x86, gcc-4.6: Use gcc -m options when building vdso 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. Reported-by: H. J. Lu Signed-off-by: H.
