[RFC 01/23] ARM: LPAE: disable phys-to-virt patching on PAE systems

[Cyril Chemparathy]

From: Vitaly Andrianov <vitalya at ti.com>

The current phys-to-virt patching mechanism is broken on PAE machines with
64-bit physical addressing.  This patch disables the patching mechanism in
such configurations.
