Hi Jeff,

Your last UML patch for 2.6.0-test8 looks fine for me,
except when enabling loadable module support (CONFIG_MODULES).
.config is attached.

Known problem, I haven't got around to implementing the changes needed
for modules in 2.6.

Re: uml-patch-2.6.0-test8

[Paul Jackson]

Your 2.6.0-test8 patch from:

  http://jdike.stearns.org/mirror/uml-patch-2.6.0-test8.bz2

worked for me as well.  It built and booted at least, when applied
to a clean, current as of a few hours ago:

   bk://linux.bkbits.net/linux-2.5

But your bkbits tree, at:

  http://jdike.stearns.org:5000/uml-2.5

seems to have something quite different in it than what
I got from the above linux-2.5 + uml-patch-2.6.0-test8.bz2.

Just one UML relevant example of what I see different:

================ arch/um/kernel/Makefile ================
48c50
< QUOTE = 'my $$config=`cat $(TOPDIR)/.config`; $$config =~ s/"/\\"/g ; while(<STDIN>) { $$_ =~ s/CONFIG/$$config/; print $$_ }'
---
> QUOTE = 'my $$config=`cat $(TOPDIR)/.config`; $$config =~ s/"/\\"/g ; $$config =~ s/\n/\\n"\n"/g ; while(<STDIN>) { $$_ =~ s/CONFIG/$$config/; print $$_ }'


The '<' is from your bkbits tree, and didn't compile.
The '>' is from applying your patch, and works.

I see many other differences as well, most seemgingly unrelated
to UML.

Sorry.  My confusion.  I had the wrong tree.

The above also builds and boots UML for me now.

Thanks for this good work, Jeff.

That patch was bogus.  I replaced it with a good one, so pull it again if it
totally breaks for you.

uml-patch-2.6.0-test8

[Jeff Dike]

This patch updates UML to 2.6.0-test8.

The 2.6.0-test5 UML patch is available at
	http://jdike.stearns.org/mirror/uml-patch-2.6.0-test8.bz2

BK users can pull my 2.5 repository from
	http://jdike.stearns.org:5000/uml-2.5
