with this config:

i've saved the merged 2.6.26-rc8-tip-00241-gc6c8cb2-dirty tree into tip/tmp.x86.xen-64bit.Sun_Jun_29_10 and pushed it out, so you can test that exact version.

Looks like the setup.c unification missed the early_ioremap init from the early_ioremap unification. Unconditionally call early_ioremap_init().

applied to tip/x86/unify-setup - thanks Jeremy.

I've reactived the x86/xen-64bit branch and i'm testing it currently.

-tip auto-testing found pagetable corruption (CPA self-test failure):

config and full log can be found at:

http://redhat.com/~mingo/misc/config-Mon_Jun_30_11_11_51_CEST_2008.bad

That config doesn't build for me. When I put it in place and do "make oldconfig" it still asks for lots of config options (which I just set to default). But when I build it fails with:

I can fix that, of course, but it doesn't give me confidence I'm testing what you are...
