Subject: [RFC 01/23] ARM: LPAE: disable phys-to-virt patching on PAE systems
Date: Mon, 23 Jul 2012 21:09:03 -0400 [thread overview]
Message-ID: <1343092165-9470-2-git-send-email-cyril@ti.com> (raw)
In-Reply-To: <1343092165-9470-1-git-send-email-cyril@ti.com>
From: Vitaly Andrianov <vitalya@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.
