[Xen-devel] PAE xen + linux kernel boots ...

[Gerd Knorr <kraxel@xxxxxxxxxxx>]

... linux userspace doesn't come up yet though, thus it is still some
way to go.  I didn't even chech whenever non-pae still works with my
current code base.

If you want to have a look nevertheless, patches are here:

  Xen: http://dl.bytesex.org/patches/xen-4/pae-support
  Linux: http://dl.bytesex.org/patches/linux-xen-4/

The most intresting patch for Linux is "pae-support" as well (for
those who just want read the diffs).  To build a kernel you need
all of them, on top of a vanilla 2.6.11 kernel, applied in the
order specified in the "series" file.

Comments?  Questions?
