This also affects alpha:allmodconfig and m68k:allmodconfig. The problem was introduced with 'interconnect: Teach lockdep about icc_bw_lock order'.
#include <linux/sched/mm.h> is missing. Presumably that is included indirectly in the upstream kernel, but I wasn't able to determine which commit added it.
Yeah, I added a fixup commit for the next release to address that issue, thanks for the report!
