asm-generic: make copy_from_user() zero the destination properly [ Upstream commit 2545e5da080b4839dd859e3b09343a884f6ab0e3 ] ... in all cases, including the failing access_ok() Note that some architectures using asm-generic/uaccess.h have __copy_from_user() not zeroing the tail on failure halfway through. This variant works either way. Cc: stable@vger.kernel.org Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Sasha Levin <alexander.levin@verizon.com>
