[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

Is the http://xenbits.xensource.com/linux-2.6-xen.hg tree still being
updated? if not, what''s the preferred Linux tree to track that has all
of the Xen bits?
Thanks,

[RFC PATCH 00/33] Xen i386 paravirtualization support
Unlike full virtualization in which the virtual machine provides
the same platform interface as running natively on the hardware,
paravirtualization requires modification to the guest operating system
to work with the platform interface provided by the hypervisor.
Xen was designed with performance in mind. Calls to the hypervisor
are minimized, batched if necessary, and non-critical codepaths
