So there, asm/mmu.h includes asm/percpu.h, which includes asm/paca.h, which
includes asm/mmu.h.

I suspect that we can remove asm/paca.h from asm/percpu.h as it *seems*
to be only used by the #define __my_cpu_offset but I don't know if anything
will break further, especially if this __my_cpu_offset is used anywhere
without this paca definition.
