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