[patch 0/8] Basic infrastructure patches for a paravirtualized kernel
Hi Andrew,
This series of patches lays the basic ground work for the

The main change from the last posting is that all the page-table
related patches have been moved out, and will be posted separately.
Also, the off-by-one in reserving the top of address space has been
