Fix PAE shadow on a machine with RAM above 4G on x86_64 xen. Currently, on a machine with RAM above 4G, we can not run 32bit VMX guest on x86_64 xen, the root cause is that the PAE page table PDPT must below 4G, this patch fixes this issue. Also did some cleanup.

Hello. log of the crashing boot process: http://pasik.reaktio.net/xen/pv_ops-dom0-debug/pv_ops-dom0-bootlog-14-xen331-linux-2.6.29-rc6-crash.txt 2.6.29-rc5 based pv_ops dom0 works on the same computer.. with the same Xen version. I tried with and without pci=nomsi. adding ''noapic'' doesn''t seem to help (I need that with 2.6.29-rc5 to make it work). Any ideas

Hi, Following is a simple patch that is needed in nouveau to get accelerated X on a Xen dom0 pv_ops kernel. The kernel is jeremy's 2.6.31.6 as of 20100222. The whole gpu tree of nouveau (which is almost the mainline merge), was substituted into the kernel-tree. All components of X (mesa, Xorg-server-7.5, xf86-nouveau, libdrm) used of the same day. Patch: diff -Naur

Hi, AFAIK, the status of Xen in lenny is currently the following: - no dom0 kernel - domU kernel only for i386 (no domU kernel for amd64) I was told (I don't remember where) that this is because the vanilla kernel only supports domU for i386, and has no dom0 support, so distros have to port the patches to their kernels (please correct me if I'm wrong). However: - etch shipped with dom0
