While looking what kind of fix got applied for one of the
improvements, I noticed it
didn't get fixed at all. But m68k/allmodconfig is broken due to an
unrelated change, after
which the build stops, so it never got to compile the file I was looking into.

Would it be possible to build with `make -k', so it continues in case
of an error, and
tries to build as much as possible?
Yes, I know this may increase build time considerably, but in an ideal
world, there
are no compile errors and everything is built anyway ;-)

Thanks!

Well, the mips tree in linux-next is
git://git.linux-mips.org/pub/scm/upstream-sfr.git#mips-for-linux-next and
I fetch it every day.

I only have the new bits in linux-next but not the pending for the current
work-in-progress kernel, that is 3.0.  Those are queued in

http://git.linux-mips.org/?p=upstream-linus.git;a=summary
git://git.linux-mips.org/pub/scm/upstream-linus.git

and I've sent two pull requests to Linus so far which went without
reaction ...

Maybe linus had missed them, sadly.

Done (I think - it required very simple changes to a Python script and I
only do "monkey see, monkey do" Python programming :-))

I also made the mistake of fixing things so that the automatic "git
bisect for build failures" would work.  That was taking much too much
time (over 4 hours for one build), so I have turned it off.  Hopefully,
the builds will now run in a more reasonable time frame.

Yeah, I noticed it. There are still no results for 3.0-rc4...

Probably you should only bisect for configs that where "green" recently.
And hope people fix reported regressions the-next-day-as-we-speak :-)

3.0-rc4 should be complete in a few hours.  Hopefully rc5 will be faster.

Well, I will leave that for the author :-)

Completed at 101% 108/107! :-)
But there are only 107 logs on the page.

Anyway, the "-k" seems to work: much more problems in the logs. Thanks!
