latest 3.0 tree

[Kip Macy]

I just did a pull, deleted my -xen0 and -xenU trees, and did a make
world. I've pulled all the latest device changes into my centos 4
tree. When I start it up as a domU it fails - the issue is that dom0
oopses when xen_blk tries to register itself (and times out).

serial console:
(XEN) DOM0: (file=mm.c, line=446) Bad L1 flags 100

Hi,

I had the same problem. A make mrproper seems to have fixed the
problem for me. I am not too sure what the cause of the problem is. I
noticed that CONFIG_HIGHMEM4G is now a default setting for 2.6 kernel
but I am not sure if this has anything to do with it.
