Version 2 This version of the patch series fixes compilation errors for 32 bit x86 targets. Version 1 This patch series optimized CRC32C calculations with PCLMULQDQ instruction for crc32c-intel module. It speeds up the original implementation by 1.6x for 1K buffer and by 3x for buffer 4k or more. The tcrypt module was enhanced for doing speed test on crc32c calculations.
Herbert - you are handling this one, right? -hpa -- H. Peter Anvin, Intel Open Source Technology Center I work for Intel. I don't speak on their behalf.
