2013-05-30x86, crc32-pclmul: Fix build with older binutilsJan Beulich
binutils prior to 2.18 (e.g. the ones found on SLE10) don't support assembling PEXTRD, so a macro based approach like the one for PCLMULQDQ in the same file should be used. This requires making the helper macros capable of recognizing 32-bit general purpose register operands.

2013-01-19crypto: crc32 - add crc32 pclmulqdq implementation and wrappers for table ↵Alexander Boyko
implementation This patch adds crc32 algorithms to shash crypto api. One is wrapper to gerneric crc32_le function. Second is crc32 pclmulqdq implementation. It use hardware provided PCLMULQDQ instruction to accelerate the CRC32 disposal. This instruction present from Intel Westmere and AMD Bulldozer CPUs. For intel core i5 I got 450MB/s for table implementation and 2100MB/s for pclmulqdq implementation.
