From: Michael Chan [ Upstream commit 9d13744bb75078175ab49408f2abb980e4dbccc9 ] There is a code path where we are calling __iowrite64_copy() on an address that is not 64-bit aligned. This causes an exception on some architectures such as arm64. Fix that code path by using __iowrite32_copy(). Reported-by: JD Zheng Signed-off-by: Michael Chan Signed-off-by: David S.
