pgd_alloc and [cd]tors
Is there any real use in having a ctor/dtor for the pgd cache? Given
that all pgd allocation happens via pgd_alloc/pgd_free, why not just
fold the [cd]tor in?
I'm asking because Xen wants pgd[3] to be unshared in the PAE case, and
it looks to me like the easiest way to handle that is by making
pgd_alloc/free pv-ops and doing the appropriate thing in the Xen code.

[RFC] VMI for Xen?
I''m sure everyone has seen the drop of VMI patches for Linux at this
point, but just in case, the link is included below.
I''ve read this version of the VMI spec and have made my way through most
of the patches. While I wasn''t really that impressed with the first
spec wrt Xen, the second version seems to be much more palatable.
Specifically, the code inlining and
