enable_kernel_altivec() has to be called with disabled preemption.
Let's make this explicit, to prepare for pagefault_disable() not
touching preemption anymore.

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.

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>).
