Subject: UML boot failure with kinit

UML now compiles on 2.6.17-rc4-mm3, but it fails to boot:

[...]
kinit: do_mounts
kinit: name_to_dev_t(98:0) = dev(0,0)
kinit: root_dev = dev(0,0)
kinit: trying to mount /dev/root on /root with type ext3
kinit: Cannot open root device dev(0,0)
[...]

Adding 'root=ubda' to the command line cures it.

hpa fixed this yesterday. Something in klibc didn't support decimal
mm:nn device specifications.

Jeff Dike reported this one yesterday; it's fixed in my git tree.
