Matthew Wilcox 2c6deb0152 bitmap: use memcmp optimisation in more situations ... Commit 7dd968163f ("bitmap: bitmap_equal memcmp optimization") was rather more restrictive than necessary; we can use memcmp() to implement bitmap_equal() as long as the number of bits can be proved to be a multiple of 8. And architectures other than s390 may be able to make good use of this optimisation.
