Hello,

current mainline (v2.6.38-7210-gb81a618) on ARM/mxs has the following build failure:

After reverting these patches the kernel compiles...

No time to boot the kernel, though.

Sorry about that, Marc.  I have a patch at

which should fix the issue for you (and I tested it with my arm cross 
compiler).
