    Subject[patch 3/3] crypto: padlock-aes: enable on 64-bit kernels
    From: Sebastian Andrzej Siewior <>
    crypto: padlock-aes: enable on 64-bit kernels

    The only required change now is using the right push/pop instruction
    on x86-64. Taken from the original patch by Sebastian Andrzej Siewior.
    (Added a dependency on X86.)
