From cfc6a554d7a364997a43964b4b1290487f890447 Mon Sep 17 00:00:00 2001 From: Eric Miao Date: Tue, 7 Sep 2010 15:10:14 +0800 Subject: ARM: pxa: fix cpu_is_pxa*() not expanding to zero when not configured When CONFIG_PXA3xx is not selected, cpu_is_pxa3xx() doesn't expand to zero, which in some places doesn't result in correct optimization.
