From a05e54c103b0b8e1dab5d04b411f1d48387c4903 Mon Sep 17 00:00:00 2001 From: Liu Hua Date: Fri, 18 Apr 2014 09:43:32 +0100 Subject: ARM: 8031/2: change fixmap mapping region to support 32 CPUs In 32-bit ARM systems, the fixmap mapping region can support no more than 14 CPUs(total: 896k; one CPU: 64K). And we can configure NR_CPUS up to 32. So there is a mismatch. This patch moves fixmapping region downwards to region 0xffc00000- 0xffe00000. Then the fixmap mapping region can support up to 32 CPUs.
