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 are a number of open
questions throughout the series, resolving of which is the main goal
of this early posting.
01: unify update_runstate_area()
02: x86: split populating of struct vcpu_time_info into a separate function
03: domain: GADDR based shared guest area registration alternative - cleanup
04: domain: update GADDR based runstate guest area
05: x86: update GADDR based secondary time area
06: x86/mem-sharing: copy GADDR based shared guest areas
07: domain: map/unmap GADDR based shared guest areas
08: domain: introduce GADDR based runstate area registration alternative
09: x86: introduce GADDR based secondary time area registration alternative
10: common: convert vCPU info area registration
These go on top of the previously posted small bug fixes "common:
map_vcpu_info() wants to unshare the underlying page" and "x86: also
zap secondary time area handles during soft reset".
