crypto: x86 - Remove include/asm/inst.h Current minimum required version of binutils is 2.23, which supports PSHUFB, PCLMULQDQ, PEXTRD, AESKEYGENASSIST, AESIMC, AESENC, AESENCLAST, AESDEC, AESDECLAST and MOVQ instruction mnemonics. Substitute macros from include/asm/inst.h with a proper instruction mnemonics in various assmbly files from x86/crypto directory, and remove now unneeded file. The patch was tested by calculating and comparing sha256sum hashes of stripped object files before and after the patch, to be sure that executable code didn't change.

crypto: crc32-pclmul - remove useless relative addressing In 32-bit mode, the x86 architecture can hold full 32-bit pointers. Therefore, the code that copies the current address to the %ecx register and uses %ecx-relative addressing is useless, we could just use absolute addressing. The processors have a stack of return addresses for branch prediction. If we use a call instruction and pop the return address, it desynchronizes the return stack and causes branch prediction misses. This patch also moves the data to the .rodata section. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

x86, crc32-pclmul: Fix build with older binutils 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.

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.
