Date: Sun, 06 Mar 2011 22:08:03 +0000 From: Ben Hutchings <ben@...adent.org.uk> To: Peter Zijlstra <a.p.zijlstra@...llo.nl>, Paul Mackerras <paulus@...ba.org>, Ingo Molnar <mingo@...e.hu>, Arnaldo Carvalho de Melo <acme@...stprotocols.net> Cc: LKML <linux-kernel@...r.kernel.org> Subject: [PATCH] perf: Define make variables ARCH and SRCARCH consistently with Kbuild It is confusing to use RAW_ARCH/ARCH instead of ARCH/SRCARCH. The current definitions also make it difficult to build for i386 on an x86_64 host.
