Subject: powerpc/mm: Fix compile error of pgtable-ppc64.h
From: Li Zhong <zhong@xxxxxxxxxxxxxxxxxx>
commit fd120dc2e205d2318a8b47d6d8098b789e3af67d upstream.
It seems that forward declaration couldn't work well with typedef, use
struct spinlock directly to avoiding following build errors:
In file included from include/linux/spinlock.h:81,
from include/linux/seqlock.h:35,
from include/linux/time.h:5,
from include/uapi/linux/timex.h:56,
from include/linux/timex.h:56,
from include/linux/sched.h:17,
from arch/powerpc/kernel/asm-offsets.c:17:
include/linux/spinlock_types.h:76: error: redefinition of typedef 'spinlock_t'
/root/linux-next/arch/powerpc/include/asm/pgtable-ppc64.h:563: note: previous declaration of 'spinlock_t' was here
