Thanks for the quick fix! git grep shows this:
lib/atomic64.c: addr >>= L1_CACHE_SHIFT;
So this patch is a prerequisite for the GENERIC_ATOMIC64 patch.
git grep also shows
arch/score/include/asm/cache.h:#define L1_CACHE_SHIFT 4
arch/unicore32/include/asm/cache.h:#define L1_CACHE_SHIFT (5)
So the other two archs are fine.
Thanks,
Fengguang
