From: Eric Biggers <ebiggers@xxxxxxxxxx> This series fixes the bug reported by Liu Chao (found using syzkaller) where a crash occurs in scatterwalk_pagedone() on architectures such as arm and arm64 that implement flush_dcache_page(), due to an invalid page pointer when walk->offset == 0. This series attempts to address the underlying problem which is that scatterwalk_pagedone() shouldn't have been called at all in that case.
