[0/4] hvm: add hvm_funcs hooks for msr intercept handling

Message

This patch series aims to make the msr intercept handling, performed in
vpmu code, virtualization technology agnostic.
It creates a common interface for setting/clearing the msr intercepts and
then add hooks to the corresponding hvm_funcs table to be able to call the
svm/vmx specific handlers through a generic hvm wrapper function.

Xenia Ragiadakou (4):
  x86/vpmu: rename {svm,vmx}_vpmu_initialise to
    {amd,core2}_vpmu_initialise
  x86/svm: split svm_intercept_msr() into
    svm_{set,clear}_msr_intercept()
  x86/vmx: replace enum vmx_msr_intercept_type with the msr access flags
  x86/hvm: create hvm_funcs for {svm,vmx}_{set,clear}_msr_intercept()
