From 6affb4826405dc1f53bae0e5c302a18f734a44ca Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Mon, 25 Mar 2013 18:19:11 +0000 Subject: [PATCH] ARM: tegra: use setup_mm_for_reboot rather than explicit pgd switch This patch changes the Tegra PM code to use the setup_mm_for_reboot helper rather than call cpu_switch_mm directly. This keeps things like TLB invalidation in one place.
