Hmm while we are discussing twisted things; would it be possible to
implement writable page tables in the guest rather than in Xen?
On a related note, is there any way of querying the pinning status of
pages from Xen? I used to have two global bitmaps in the guest, one for
l1 and one for l2, but I suppose I could just as well add a
get-pinned-status(mfn) hypercall to Xen, if there is not one already?
Or I could add this info to struct page in Linux.
thanks,
Jacob
