[PATCH v2 0/2] KVM: SVM: Create separate vmcbs for L1 and L2

[Cathy Avery]

svm->vmcb will now point to either a separate vmcb L1 ( not nested ) or L2 vmcb ( nested ).

Changes:
v1 -> v2
 - Removed unnecessary update check of L1 save.cr3 during nested_svm_vmexit.
 - Moved vmcb01_pa to svm.
 - Removed get_host_vmcb() function.
 - Updated vmsave/vmload corresponding vmcb state during L2
   enter and exit which fixed the L2 load issue.
 - Moved asid workaround to a new patch which adds asid to svm.
 - Init previously uninitialized L2 vmcb save.gpat and save.cr4

Tested:
kvm-unit-tests
kvm self tests
Loaded fedora nested guest on fedora
