From 7e5e6e9a509c4ed2973a345ec7ffb96577f42e26 Mon Sep 17 00:00:00 2001 From: Russell King <rmk@dyn-67.arm.linux.org.uk> Date: Thu, 3 Nov 2005 20:32:45 +0000 Subject: [PATCH] [ARM SMP] Do not clear cpu_vm_mask for VIPT caches Since we do not invalidate TLBs/caches on MM switches, we should not clear the cpu_vm_mask for the CPU.
