Actually, I was going to suggest this patch, but I wasn't sure if you'd
want it (this patch might be handy if you're interested in eventually
submitting UML for inclusion into Linus's kernel):

So if you want to build a kernel for your host system, you wouldn't need
to do anything different. If you want to build a user-mode Linux kernel
for your system, all you need to do is one of two options:

make ARCH=um config dep clean linux

or:

"export ARCH=um" or "setenv ARCH um" in your shell.


In any case, would you care to comment on the topic of integrating UML
into the standard Linux kernel tree? Are you for it? What does Linus think
(if he's commented on the subject in the past)?
