v7: - fix "BUG: smp_processor_id() in preemptible [00000000] code" reported by Halil, using get_cpu/put_cpu instead of calling smp_processor_id() directly. - fix a possible spinlock recursion in virtcrypto_dataq_callback(), we should release the spinlock before invoking the callback. - rebase on the latest kernel master tree. v6: - add patch 1/2 to make sparc architecture
