Oops sorry about that, I didn't expect that change to break the x86
build so I didn't test it there, but it's because of CONFIG_COMPILE_TEST.
a5f4ca68f348 is the offending commit, and reverting it would fix it (it
was just a tidyup). But this change below also works. That include was
to build ARM_PMU_PROBE which is only used in perf_event_v6.c (and v7)
which both already include asm/cputype.h. Although maybe that would be a
bit of a hack.
