Would it be possible to add page status query to the hypercalls? E.g. return the status and owner for just one page, without trying to on/offline it?

The same goes for the CPU hotplug code, but that's another issue.

The Solaris FMA code likes to have the option of querying the status, so that's why we'd like to have such an option.
