[PATCH v2 0/3] hvm: add hvm_funcs hooks for msr intercept handling

[Xenia Ragiadakou <xenia.ragiadakou@xxxxxxx>]

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.

Version 2 addresses the comments made on version 1 to ease further review.

Still there is a pending question made by Jan, whether there could be other,
than the vpmu one, use cases that would require msr intercept handling to be
performed outside of virtualization techonology-specific code, and whether
this abstraction is actually usefull to have.

Xenia Ragiadakou (3):
  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()
