Thanks for applying the patch!

Can you add my Tested-by (see [1]), thanks!
( I compiled 8 (in words eight) Linux-Next kernels to catch all
regressions and setup my desired kernel-config options. )

$ uname -r
3.8.0-rc3-next20130114-8-iniza-generic

$ cat /proc/version
Linux version 3.8.0-rc3-next20130114-8-iniza-generic
(sedat.dilek@...il.com@...box) (gcc version 4.6.3 (Ubuntu/Linaro
4.6.3-1ubuntu5) ) #1 SMP Tue Jan 15 10:05:32 CET 2013

And YES, I am running that kernel(s) in my daily working environment.
My -8 kernel run successfully all LTP-lite tests...
...which is a good orientation for a localmodconfig-ed kernel (minimal
setup) but does not mean this release has no other bugs which I did
not hit in my environment.
