FYI, this patch introduced regression (kernel crash) at least on Amstrad
E1 board (where FIQ is used for the keyboard). See the following thread:
http://marc.info/?t=137583169900003&r=1&w=2

So any stable kernels where this patch was added should also take:

	commit 2ba85e7af4c639d933c9a87a6d7363f2983d5ada
	Author: Russell King <rmk+kernel@xxxxxxxxxxxxxxxx>
	Date:   Thu Aug 8 11:51:21 2013 +0100

	ARM: Fix FIQ code on VIVT CPUs

That patch fixes the regression.
