It is actually against -n900 tree, sorry about that. But this means
that this regression likely will not hit -next :-).

Agreed.

I found few more compile problems, but those are neither easy nor I
expect them to happen commonly. In particular BIG_ENDIAN=y breaks
flexcan, MMU=n break some core code, and CONFIG_ARM_KPROBES_TEST=y
just does not work with my compiler here. Probably not worth trying to
reproduce on vanilla tree?

Thanks,
