Ian,

please try the following two patches on top of v3.13-rc8 and report
back, if it solves the regression.

I have tested this on a revived non-DT Kirkwood Dockstar with and
without DT support enabled. I also compile tested it for Orion5x
and Dove.

While I will not send any patches for non-DT mach-dove boards as
none of them is really used anymore, Gregory is on Cc for hopefully
testing orion5x.

For possible -stable patches, I know it is quite a huge patch but
I didn't dare to touch arch/arm/kernel/foo for this kind of regression.

Sebastian

(I hope the fscking Thunderbird inlines both patches correctly)
