linux-next: build failure after merge of the final tree (powerpc tree related)

Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/gpio/langwell_gpio.c: In function 'lnw_irq_handler':
drivers/gpio/langwell_gpio.c:210: error: 'struct irq_desc' has no member named 'chip'
drivers/gpio/langwell_gpio.c:211: error: 'struct irq_desc' has no member named 'chip'

Caused by commit 17b9f9e2653a ("powerpc: Enable
GENERIC_HARDIRQS_NO_DEPRECATED") enabling
CONFIG_GENERIC_HARDIRQS_NO_DEPRECATED for powerpc without previously
fixing up the above driver.

I have reverted that commit for today.

Except that the above driver has nothing to do with powerpc, it's some
Intel Moorestown stuff...

It should be fixed regardless I suppose, CC'ing Thomas.

Cheers,
Ben.

I've had to make fixes to this driver in sparc64 allmodconfig builds
too :-)

Sigh. Yes, this wants to depend on x86 in the first place.

But this is the second instance of blindly and mindlessly changing eoi
to irq_eoi w/o looking at the reason for this change.

Those patches should have been rejected based on their changelog in
the first place:

    Latest kernel has many changes in IRQ subsystem and its interfaces, like
    adding "irq_eoi" for struct irq_chip, this patch is a follow up change
    for that.

When noone beats me to fix that mess, I'll do it tomorrow morning.

Thanks,
