Noteworthy differences from map_vcpu_info(): - remote vCPU-s are paused rather than checked for being down (which in principle can change right after the check), - the domain lock is taken for a much smaller region, - the error code for an attempt to re-register the area is now -EBUSY, - we could in principle permit de-registration when no area was previously registered (which would permit "probing", if necessary for anything).

Furthermore for 64-bit PV domains the area is inaccessible (and hence cannot be updated by Xen) when in guest-user mode. Introduce a new vCPU operation allowing to register the secondary time area by guest-physical address. An at least theoretical downside to using physically registered areas is that PV then won't see dirty (and perhaps also accessed) bits set in its respective page table entries.

Furthermore for 64-bit PV domains the areas are inaccessible (and hence cannot be updated by Xen) when in guest-user mode, and for HVM guests they may be inaccessible when Meltdown mitigations are in place. (There are yet more issues.) In preparation of the introduction of new vCPU operations allowing to register the respective areas (one of the two is x86-specific) by guest-physical address, flesh out the map/unmap functions. Noteworthy differences from map_vcpu_info(): - areas can be registered more than once (and de-registered), - remote vCPU-s are paused rather than checked for being down (which in principle can change right after the check), - the domain lock is taken for a much smaller region.

Note that pages aren't marked dirty when written to (matching the handling of space mapped by map_vcpu_info()), on the basis that the registrations are lost anyway across migration (or would need re- populating at the target for transparent migration). Plus the contents of the areas in question have to be deemed volatile in the first place (so saving a "most recent" value is pretty meaningless even for e.g. snapshotting).

Also remove the bogus copy_domain_page(): should be placed before the call to map_vcpu_info(), as the later can update the contents of the vcpu_info page. Note that this eliminates a bug in copy_vcpu_settings(): The function did allocate a new page regardless of the GFN already having a mapping, thus in particular breaking the case of two vCPU-s having their info areas on the same page.
