[patch 00/37] genirq: Remove __do_IRQ() and cleanup irq related Kconfigs

[patch 00/37] genirq: Remove __do_IRQ() and cleanup irq related Kconfigs

[Thomas Gleixner]

Now that rc1 is out, I got reliable information about the remaining
users of __do_IRQ(), which block the removal:

  arch/cris, arch/h8300, arch/m32r

The following series converts these architectures to proper flow
handlers and removes __do_IRQ(). Aside of that if cleans up the irq
related Kconfigs in the architectures and switches them to the generic
Kconfig in kernel/irq/

The __do_IRQ() removal is only compile tested, but

 - the CRIS maintainer said some time ago he is fine with breakage
   and will deal with the fallout

 - h8300 and m32r are basically unmaintained. The last updates from
   the maintainer side have been more than a year ago.

The conversion of all 3 architectures is straight forward and with low risc,
though it's only compile tested with all available defconfigs as far as it
goes. Some of them do not build in vanilla either, but the converted files
build fine.

The last chunk of this patch series is a straight forward conversion
of architectures to use the generic irq Kconfig file. Compile tested
and boot tested on a few.

That said, if there are no objections and Linus does not go berserk on
me, I'd like to get over with this right now.

Thanks,

[patch 02/37] h8300: Convert interrupt handling to flow handler

[Thomas Gleixner]

[-- Attachment #1: h8300-convert-to-flow-handler.patch --]
[-- Type: text/plain, Size: 1556 bytes --]

__do_IRQ is deprecated so h8300 needs to be converted to proper flow
handling. The irq chip is simple and does not required any
mask/ack/eoi functions, so we can use handle_simple_irq.

[patch 04/37] cris: Use irq handling wrapper

[Thomas Gleixner]

[-- Attachment #1: cris-use-irq-handling-wrapper.patch --]
[-- Type: text/plain, Size: 707 bytes --]

Use the wrapper around __do_IRQ() so we can convert V10 and V32
seperately.

[Thomas Gleixner]

Convert the irq_chip functions and install handle_simple_irq for each

[patch 08/37] m32r: Cleanup direct irq_desc access

[Thomas Gleixner]

[-- Attachment #1: m32r-cleanup-direct-irq-desc-access.patch --]
[-- Type: text/plain, Size: 35277 bytes --]

The irq descriptors are already initialized by the generic
code. Remove the redundant init code and set the irq chip with the
proper accessor function.

[patch 09/37] m32r: Convert m32104ut irq handling

[Thomas Gleixner]

[-- Attachment #1: m32r-convert-m32104ut.patch --]
[-- Type: text/plain, Size: 3262 bytes --]

Convert the irq chips to the new functions and use proper flow
handlers. handle_level_irq is appropriate.

[patch 10/37] m32r: Convert m32104ut irq chip

[Thomas Gleixner]

[-- Attachment #1: m32r-convert-m32700ut-m32700ut_irq_type.patch --]
[-- Type: text/plain, Size: 4583 bytes --]

Convert the irq chips to the new functions and use proper flow
handlers. handle_level_irq is appropriate.

[patch 16/37] m32r: Convert mappi3 irq chip

[Thomas Gleixner]

[-- Attachment #1: m32r-convert-mappi3.patch --]
[-- Type: text/plain, Size: 4679 bytes --]

Convert the irq chips to the new functions and use proper flow
handlers. handle_level_irq is appropriate.

[patch 18/37] m32r: Convert opsput irq chip

[Thomas Gleixner]

[-- Attachment #1: m32r-convert-opsput-opsput_irq_type.patch --]
[-- Type: text/plain, Size: 4985 bytes --]

Convert the irq chips to the new functions and use proper flow
handlers. handle_level_irq is appropriate.

[patch 20/37] m32r: Convert opsput lanpld irq chip

[Thomas Gleixner]

[-- Attachment #1: m32r-convert-opsput-lanpld-type.patch --]
[-- Type: text/plain, Size: 2483 bytes --]

Convert the irq chips to the new functions and use proper flow
handlers. handle_level_irq is appropriate.

[patch 23/37] m32r: Convert to generic irq Kconfig

[Thomas Gleixner]

[-- Attachment #1: m32r-convert-to-generic-irq-Kconfig --]
[-- Type: text/plain, Size: 921 bytes --]

Use the generic irq Kconfig. Select GENERIC_HARDIRQS_NO_DEPRECATED as
we have converted all irq_chip functions.

One could hope this was nicely documented in kernel/irq/Kconfig.
But that file contains only 9 lines of comments for 10 config symbols.

Maybe it is just me but I was struggeling understanding the purpose
of these config symbols.

I found the individual bits of genirq nicely documented in most cases.
But the overall picture was/is hard to get.

And I never got enough understanding to write up something myself :-(

Not quite true ... you take out GENERIC_HARDIRQS but select
HAVE_GENERIC_HARDIRQS ... is that right?

Plus, it doesn't apply:

Hunk #1 FAILED at 12.
Hunk #2 FAILED at 65.
2 out of 2 hunks FAILED -- saving rejects to file
arch/parisc/Kconfig.rej

It looks like it was made before we did our generic irq conversion in
the 2.6.36 merge window.

You meant 38 window :) Patch is against 38-rc1 but depends on [patch
24/37] genirq: Remove __do_IRQ in this very same series.

No ... it went in when Kyle was maintainer ... so that's at least 37 or
before.

I'm not sure it's legal to have two "config TILE" blocks in this Kconfig
file; there's already one further down.

Looking at other top-level arch Kconfigs, it does seem common to have the
"config $ARCH" block at the top, though, so if you want to move the
existing "config TILE" block to the top of the Kconfig as part of this
change, that's fine too.

It is OK to have two "config TILE" blocks.
You should take care of moving the other one up after this goes in.

I'm certainly ok with this series. It would be good to finally get rid
of this legacy interface, and there's no longer any reason to hold it
up. And getting rid of hundreds of lines of code is good too.

I submitted series to clean these 3 up as well (but only got a response
from the cris folks...) If the other 2 are effectively unmaintained,
should I just submit the clean ups to you? (I think there were some
