[XEN PATCH v2 0/5] x86: make Intel/AMD vPMU & MCE support configurable

[Sergiy Kibrik <Sergiy_Kibrik@xxxxxxxx>]

Here's a second attempt to separate support of Intel & AMD CPUs in Xen build.
The code to drive both platforms used to be built unconditionally, until recent
introduction of CONFIG_{AMD,INTEL} Kconfig options.

This series extends coverage of these options on vpmu and mcheck subsystems,
which allows not to build Intel or AMD vpmu/mcheck support if CPU vendor's 
support
was explicitly disabled.

Since v1 series one patch had been merged independently, and one more got to be
squashed, so series became shorter. Specific changes since v1 are provided 
per-patch.

  x86/vpmu: separate amd/intel vPMU code
  x86/intel: move vmce_has_lmce() routine to header
  x86/MCE: guard access to Intel/AMD-specific MCA MSRs
  x86/MCE: guard {intel/amd}_mcheck_init() calls
  x86/MCE: optional build of AMD/Intel MCE code
