Hi Russell,

Good to hear that you are back online. Do you want me to rework this
patch somehow, or is it ready to be queued for upstream merge? I'm
asking because I have a pile of patches that depend on this one.

Cheers,

I guess it's ok; with 10 bits we're at the maximum which the generic
kernel supports (see linux/hardirq.h)

Hi again Russell,

Will you pick up this one in your tree as-is, or would you like me to
resubmit it somehow?

Perhaps you prefer that we take it with the other changes through the
genesis-2.6 tree?

Sorry to bother you if this has already been sorted. I just noticed
that the patch isn't part of the latest linux-next.

Thanks,

/ magnus

Russell,

I don't seem to find this patch in your -devel branch. I posted a same
version of patch earlier, so I'd also like to see this get merged.

Getting it into the patch system would be a big help, but since I've
closed my tree down for this merge window already, it's missed the
boat.  (With Linus' new "random" behaviour wrt when things happen, I'm
not planning on a second ARM kernel pull request - and the first was
sent last night.)

This is probably the patch I was referring to in my notice of closure
when I said:
| I know there was someone who was complaining a week or so ago that I
| hadn't applied their patch, which was only sent to the mailing list.
| Unfortunately, it being only on the mailing list and not in the patch
| system means I can't find it, nor the complaint about it not being
| applied.
|
| Whoever it was, sorry.

Especially as it's 4000 messages back in this mailbox!

It's there now:

http://www.arm.linux.org.uk/developer/patches/viewpatch.php?ida38/1

Anything I can do to make a second pull request happen? There are
quite a few patches that depend on this one, so I posted it well in
advace at March 10. The patch was kindly reviewed by you a bit later.
And now I got an ack. Unfortunately I didn't proceed and submit it to
the ARM-specific patch tracking system.

I don't mean to push, and I fully understand that workload due to such a
short -rc phase this time. Just wondering this can actually be made into
