[PATCH 0/2] KVM: nSVM: do not access MSR permission bitmap before KVM_RUN

From: Paolo Bonzini

Similar to what we need to do for VMX, the MSR permission bitmap
should not be accessed until the first KVM_RUN. This is important
because the memory map might not be up-to-date at the time of
KVM_SET_NESTED_STATE.

KVM: x86: rename KVM_REQ_GET_VMCS12_PAGES
KVM: nSVM: delay MSR permission processing to first nested VM run
