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

From: Cyril Chemparathy <hidden>
Date: 2012-07-24 01:13:43
Also in: lkml
Subsystem: arm port, the rest · Maintainers: Russell King, Linus Torvalds

From: Vitaly Andrianov <redacted>

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.
