#     crypto: padlock-aes - Fix Nano workaround data corruption
#     
#     This was detected by the self-test thanks to Ard's chunking patch.
#     
#     I finally got around to testing this out on my ancient Via box.  It
#     turns out that the workaround got the assembly wrong and we end up
#     doing count + initial cycles of the loop instead of just count.
#     
#     This obviously causes corruption, either by overwriting the source
#     that is yet to be processed, or writing over the end of the buffer.
#     
#     On CPUs that don't require the workaround only ECB is affected.
#     On Nano CPUs both ECB and CBC are affected.
#     
#     This patch fixes it by doing the subtraction prior to the assembly.
#
