Then we'll be stuck with request_irq_new() for the next 10 years or so.

FWIW (and appologies for hijacking the topic), Jeffs discussion about
changing the ARM integrator RTC driver has triggered a number of cleanups
in the ARM tree:

- converting the ARM integrator PL030 RTC driver to a RTC class driver

... which triggered:

- removal of the ARM dyntick code and the unused generic changes
(including the s390 and sh bits which look like they've never been
functional.)

... which triggered:

- attempting to fix a circular include dependency involving linux/irq.h
and asm-arm/mach/irq.h

... which then triggered:

- allowing PXA platform class to build for more than one PXA platform
at a time, so I don't have to run 20 (!) separate kernel builds to
check them all for breakage caused by the elimination of the
circular dependency.

... which also allowed me to find several PXA platform build bugs.

Thanks Jeff. ;)

I'm not intending pushing this stuff into mainline for a bit, although
it will appear in my public tree for others to start looking at and for
them to be aware of.

That does mean that, unfortunately, akpm's going to see those changes
and it might cause Andrew some headaches - sorry about that. You may
wish to avoid pulling the ARM 'devel' branch until the dust settles.

(Obviously the appropriate fixes will be head towards Linus at the
appropriate time.)
