3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Martin Schwidefsky <schwidefsky@xxxxxxxxxx> commit 6e0de817594c61f3b392a9245deeb09609ec707d upstream. The A register needs to be initialized to zero in the prolog if the first instruction of the BPF program is BPF_S_LDX_B_MSH to prevent leaking the content of %r5 to user space.
