Yes, that's true, the fix is in -mm, enable SKAS mode too during compilation
(even if you don't use it) and it will work. See the answer to the latest
"[uml-devel] [linux-2.6-bk] UML compile broken!" thread for this problem.

Ian, good catch, but you're quoting the wrong .cmd file. config.tmp is built
correctly, config.c is not, so you should quote .config.c.cmd.
Anyway, from looking at what you quote, it's identical to the code in
arch/um/kernel/Makefile. Quoting the correct code:
quiet_cmd_quote2 = QUOTE $@
cmd_quote2 = sed -e '/CONFIG/{' \
-e 's/"CONFIG"\;/""/' \
-e 'r $(obj)/config.tmp' \
-e 'a""\;' \
-e '}' \
$< > $@
As you see, there is a fourth expression, *here*. But it's -e '}'.
This patch went in after 2.6.11, I'm noticing - wow, are releases getting so
slow?

Can you post your sed version? and Rob, can you then test it and fix the code?
Please save the correct config.c currently created and check it for
reference.

Explained above.

The __va_copy fix, right? I'm trying to merge that in 2.6.11.7, it's under
review. The only problem is that somebody complains about the fact Linux
still supports 2.95. Luckily for you, Linus already shut them off once, so
the support won't go away soon.

You mean -rc2, ok.
