Since it was indicated that introducing specific new vCPU ops may be
beneficial independent of the introduction of a fully physical-
address-based ABI flavor, here we go. There continue to be a few open
questions throughout the series, resolving of which was one of the main
goals of the earlier postings. v4 adds one (small) new patch and
addresses review comments; see individual patches.

1: x86/shim: zap runstate and time area handles during shutdown
2: domain: GADDR based shared guest area registration alternative - cleanup
3: domain: update GADDR based runstate guest area
4: x86: update GADDR based secondary time area
5: x86/mem-sharing: copy GADDR based shared guest areas
6: domain: map/unmap GADDR based shared guest areas
7: domain: introduce GADDR based runstate area registration alternative
8: x86: introduce GADDR based secondary time area registration alternative
9: common: convert vCPU info area registration
