From 13f659b0f363114282679d06094337c5efa12fa8 Mon Sep 17 00:00:00 2001 From: Cyril Chemparathy Date: Mon, 16 Jul 2012 15:37:06 -0400 Subject: ARM: LPAE: use phys_addr_t in switch_mm() This patch modifies the switch_mm() processor functions to use phys_addr_t. On LPAE systems, we now honor the upper 32-bits of the physical address that is being passed in, and program these into TTBR as expected.
