[PATCH] powerpc/64e: Fix circular dependency with CONFIG_SMP disabled

[Christophe Leroy]

asm/percpu.h includes asm/paca.h which needs struct tlb_core_data
which is defined in mmu-e500.h

asm/percpu.h is included from asm/mmu.h in a #ifdef CONFIG_E500
before the inclusion of mmu-e500.h

To fix that, move the inclusion of asm/percpu.h into mmu-e500.h
after the definition of struct tlb_core_data
