The mm_walk structure currently mixed data and code. Split out the

When building csky:defconfig:
In file included from mm/madvise.c:30:
mm/madvise.c: In function 'madvise_free_single_vma':
arch/csky/include/asm/tlb.h:11:11: error:
invalid type argument of '->' (have 'struct mmu_gather')
I belive the macros above are missing brackets.. Can you confirm the
below takes care of things? I'll add a patch if so
