genirq: Generic irq chip available in git

[Thomas Gleixner]

The generic irq chip infrastructure patches are now available in

git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip irq/for-arm

The top commit is cfefd21e693dca791bf9ecfc9dd3794facad533c

Russell said, he'll pull that into his devel tree, so patches can be
applied there. SoC maintainers running their own git trees can pull it
as well so they can apply the patches for their platforms.

There is a small change in the interface vs. the previous posted
version:

irq_setup_generic_chip() has now an additional argument to pass init
flags in. There are two flags available right now:

 * @IRQ_GC_INIT_MASK_CACHE:     Initialize the mask_cache by reading mask reg

The original code checked for the set/clr_bit functions, but with that
change it can be used for other implementations as well.

 * @IRQ_GC_INIT_NESTED_LOCK:    Set the lock class of the irqs to nested for
 *                              irq chips which need to call irq_set_wake() on
 *                              the parent irq. Usually GPIO implementations

This is for those gpio chips which all have their own gpio_lock_class
and the setter loop.

I fixed up the patches I sent out earlier. They are available from:

  http://master.kernel.org/~tglx/patches-arm-gc.tar.bz2

if you don't want to fixup the stuff yourself.

Happy Easter!

Thanks, now pulled into the 'consolidation-irq' branch.  If people
wish to send the per-SoC patches to the patch system, or put them
in their git trees, or indeed whatever, that stuff can be merged
onto that branch so its easier to see where the IRQ consolidation
is at.

I've had nothing further from anyone on this since merging it.  If people
aren't using this stuff then there's no point it sitting in my tree, and
there's no point me sending it to mainline as part of my merges.

So I'm dropping the branch out of the merges for the time being.

Would it not make sense to go ahead and apply all the patches that
maintainers already acked?  I rather suspect many people had thought
that Thomas' future pushes of the code would also include the patches
that they'd already approved and haven't realised that they need to
manually push the patches to you.

Which involves me having to read through the entire thread yet again to
figure out what state each patch is at, save them out, edit them to add
each ack to relevant patches, copy the lot to another machine, and then
apply them.

The workload there is on the wrong person.

Yeah, I'd actually have expected Thomas to have done this when he pushed
the patches to you to be honest - certainly if I were one of the
relevant maintainers I'd have been surprised that the patches got
dropped.

I have included Thomas's davinci platform update with the relevant
acks in the following pull request. There was also a checkpatch
error that I fixed up locally. Hope this helps.

FWIW I sent a similar pull request to Kukjin a few days ago for Samsung:

I've not noticed it turning up in linux-next - in fact the linux-next stats
still looks poorly in respect of what I'd expect it to be given the amount
of stuff discussed since the last merge window.  So...

I've pulled this too in an attempt to improve the stats.  It doesn't
matter whether or not Kukjin has pulled this too.

I got the omap2/3 genriq change available at:

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6.git devel-genirq

If you want to pull pull that too. I got it also merged into omap for-next
branch as I'm still planning to rebase some init_early related clean-up on
top of that. The commit is 667a11facee70c0bd15cf07946fba71236490e07.

Regards,

Tony
