Merge branch 'msr-bitmaps' of git://git.kernel.org/pub/scm/virt/kvm/kvm

This topic branch allocates separate MSR bitmaps for each VCPU.
This is required for the IBRS enablement to choose, on a per-VM
basis, whether to intercept the SPEC_CTRL and PRED_CMD MSRs;
the IBRS enablement comes in through the tip tree.
