[PATCH 0/6] KVM: SVM: Wrap access to intercept masks into functions

[Joerg Roedel]

Hi Avi, Hi Marcelo,

this patchset wraps the access to the intercept vectors in the VMCB into
specific functions. There are two reasons for this:

	1) In the nested-svm code the effective intercept masks are
	   calculated from the host and the guest intercept masks.
	   Whenever KVM changes the host intercept mask while the VCPU
	   is in guest-mode the effective intercept masks need to be
	   re-calculated. This is nicely wrapped into these functions
	   now and makes the code more robust.

	2) These changes make the implementation of the upcoming
	   vmcb-clean-bits feature easier and also more robust (which
	   was the main reason for writing this patchset).

These patches were developed on-top of the patch-set I sent yesterday. I
tested these patches with various guests (Windows-64, Linux 32,32e and
64 as well as with nested-svm).

Regards,

	Joerg
