[PATCH 0/3 v2] Optimize CRC32C calculation using PCLMULQDQ in crc32c-intel module

[Tim Chen <tim.c.chen@linux.intel.com>]

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.
