[PATCH 00/23] ia64/xen domU take 4
Hi. This patchset implements ia64/xen domU support based on
ia64/pv_ops frame work which was sent as another patchest.
Please review and comments.
This patchset does the followings.
- Some preparation work. Mainly importing header files to define

[patch 0/8] Basic infrastructure patches for a paravirtualized kernel
Hi Andrew,
This series of patches lays the basic ground work for the
paravirtualized kernel patches coming later on. I think this lot is
ready for the rough-and-tumble world of the -mm tree.
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
