975f57fdff crypto: vmx - Fix ABI detection
When calling ppc-xlate.pl, we pass it either linux-ppc64 or
linux-ppc64le. The script however was expecting linux64le, a result
of its OpenSSL origins. This means we aren't obeying the ppc64le
ABIv2 rules.

Fix this by checking for linux-ppc64le.

It gives significant improvements ( ~+15%) on some modes.

These code has been adopted from OpenSSL project in collaboration

73613a8159 crypto: vmx - Fixing opcode issue
In build time vadduqm opcode  is not being mapped
correctly.

Adding a new map in ppc-xlate to do this.

f42613c665 linux-next: Tree for Mar 11 (powerpc build failure due to vmx crypto code)
crypto: vmx - Fix assembler perl to use _GLOBAL

Rather than doing things by hand for global symbols to deal with
different calling conventions we already have a macro _GLOBAL in
Linux to handle this.

5c380d623e crypto: vmx - Add support for VMS instructions by ASM
OpenSSL implements optimized ASM algorithms which support
VMX instructions on Power 8 CPU.

These scripts generate an endian-agnostic ASM implementation
in order to support both big and little-endian.
	- aesp8-ppc.pl: implements suport for AES instructions
	implemented by POWER8 processor.
	- ghashp8-ppc.pl: implements support for  GHASH for Power8.
	- ppc-xlate.pl:  ppc assembler distiller.

These code has been adopted from OpenSSL project in collaboration
with the original author (Andy Polyakov <appro@openssl.org>).
