Subject: mm/slab: move cache_flusharray() out of unlikely.text section
Now, due to likely keyword, compiled code of cache_flusharray() is on
unlikely.text section. Although it is uncommon case compared to free to
cpu cache case, it is common case than free_block(). But, free_block() is
on normal text section. This patch fix this odd situation to remove
likely keyword.
