Linux takes a page fault, and in the process of updating the page tables to map
the new page, it needs to allocate a new "PMD", or mid-level page directory
entry. The PV kernel cannot write its own page tables, Xen has to do that, so a
"multicall" that encapsulates two hypercalls is dispatched t
The failing code is identical in Lucid and Maverick, so I'm thinking the
difference between the two is that the Lucid fault occurs on a kernel
page, which is fatal, while the Maverick failure occurs on a user page,
which kills the process but not the kernel.

Still chewing on this. DomU should send Xen a kernel, readonly PMD
entry, but what Xen gets is a read/write user entry. I am working on
reconciling what DomU thinks it did with what Xen sees.
