>From 253e91b76e104dbdf05c5c3eaf9cbf426972c938 Mon Sep 17 00:00:00 2001 From: Tony Lindgren <tony@xxxxxxxxxxx> Date: Wed, 1 Sep 2010 16:49:13 -0700 Subject: [PATCH 3/6] ARM: Fix v7wbi_tlb_flags for SMP on UP Fix v7wbi_tlb_flags for SMP on UP. Note that we must enable MULTI_TLB to avoid undefined reference to cpu_tlb error.
