#     powerpc: Fix circular dependency between percpu.h and mmu.h
#     
#     Recently random.h started including percpu.h (see commit
#     f227e3ec3b5c ("random32: update the net random state on interrupt and
#     activity")), which broke corenet64_smp_defconfig:
#     
#       In file included from /linux/arch/powerpc/include/asm/paca.h:18,
#                        from /linux/arch/powerpc/include/asm/percpu.h:13,
#                        from /linux/include/linux/random.h:14,
#                        from /linux/lib/uuid.c:14:
#       /linux/arch/powerpc/include/asm/mmu.h:139:22: error: unknown type name 'next_tlbcam_idx'
#         139 | DECLARE_PER_CPU(int, next_tlbcam_idx);
#     
#     This is due to a circular header dependency:
#       asm/mmu.h includes asm/percpu.h, which includes asm/paca.h, which
#       includes asm/mmu.h
#     
#     Which means DECLARE_PER_CPU() isn't defined when mmu.h needs it.
#     
#     We can fix it by moving the include of paca.h below the include of
#     asm-generic/percpu.h.
#     
#     This moves the include of paca.h out of the #ifdef __powerpc64__, but
#     that is OK because paca.h is almost entirely inside #ifdef
#     CONFIG_PPC64 anyway.
#     
#     It also moves the include of paca.h out of the #ifdef CONFIG_SMP,
#     which could possibly break something, but seems to have no ill
#     effects.
#
