Hi all,

I've substantially cleaned up the Xen contiguous region handling and the
pfn/mfn translations in the dma mapping layer, and rebased everything
cleanly on top of v2.6.24.  The resulting patch queue can be viewed as
tag "dom0-2.6.24-B0" on the dom0-pvops git tree at


or equivalently on gitweb at


As usual, a mergeable, fast-forwarding development branch is being
maintained on the git master branch, with tag "dom0-2.6.24-B0-dev",
which has an identical git tree but with the full development history
behind it.

New in this release:

      * Added full mtrr support from Mark McLoughlin
      * Added xen_(create|destroy)_contiguous region handling
      * Added full Xen dma support to enable booting a dom0 kernel

Support for the dom0 xend userland is still missing, and there is no
swiotlb yet; but the dom0 kernel boots successfully on a HV and I've had
a best uptime of nearly an hour so far.  I'm getting soft lockups under
load, but it's not clear if that's a dom0 problem or a latent pv_ops
