Here's what I need to apply before I can build bk-current with UML support.
If you use Jeff's patch to 2.5.39, you then only need Makefle part of the patch,
I guess.

Jeff: BTW, UML crashes for me on shutdown quite often, if I have
CONFIG_DEBUG_SLAB enabled. Just before the crash it warns about
winch_interrupt : read failed, errno = 9
fd 57 is losing SIGWINCH support
(this is immediatelly after 'System halted.' message from kernel).
And then kernel mode fault at 0x5a5a5a5e

Bye,
