Re: [Xen-devel] Re: changeset 13403 ...

I'm dropping in on this part way through but
out of context the following sounds dangerous.

For example, Solaris domains assume at start
of time, that only pages mapped in the start
area are in use in any way. All other pages
go immediately in our free lists. If you change
this protocol, then we'll have backwards
incompatibility issues to fix.

You may even know that they only map part of
the guest physical memory and so choose to locate the intermediate
pagetables outside that mapped area.

Good point, that solves at least a part of the problem, as the read-only
mapping is needed one-way only then ...
