Martin Schwidefsky	52149ba6b0	[S390] user readable uninitialised kernel memory. ... A user space program can read uninitialised kernel memory by appending to a file from a bad address and then reading the result back. The cause is the copy_from_user function that does not clear the remaining bytes of the kernel buffer after it got a fault on the user space address.
