OK.
I had expected the breakage to be something in my tree, either an issue in a -next branch I'm using, an interaction with the CCF patches or so, or a config issue (e.g. CONFIG_CPU_IDLE became broken lately if the TWD is not in DT).

As I said, my local tree contains lots of extra patches (erhm... 233).

I do have an Armadillo.

Yes, getting rid of more legacy is good. It's just a pity for the Penguin on the Armadillo's LCD, which doesn't want to visit armadillo-multiplatform.
