ah, indeed - it was missing from tip/master due to:

| commit ac998c259605741efcfbd215533b379970ba1d9f
| Author: Ingo Molnar <mingo@xxxxxxx>
| Date:   Mon Jun 30 12:01:31 2008 +0200
|
|    Revert "x86: setup_arch() && early_ioremap_init()"
|
|    This reverts commit 181b3601a1a7d2ac3ace6b23cb3204450a4f9a27.

because that change needed the other changes from xen-64bit.

will retry tomorrow.
