0f6c10ead8 [PATCH] i4l make PCMCIA for all cards working with shared IRQ

This patch enables IRQ sharing, so these cards work again.

47c2a3aa44 [PATCH] genirq: add chip->eoi(), fastack -> fasteoi
Clean up the fastack concept by turning it into fasteoi and introducing the

This also allows the cleanup of an i386 EOI quirk - now the quirk is
cleanly separated from the pure ACK implementation.

f210be198d [PATCH] genirq: add IRQ_TYPE_SENSE_MASK
Add a #define for the mask of the part of IRQ_TYPE that represents the
trigger type.  I use that in my in-progress work as I've standardized the
way the irq description in the firmware device-tree get translated to linux
useable things by using those constants.  Having this mask to isolate the
"trigger type" part of the flags is useful in a few places.

dae8620421 [PATCH] genirq MSI fixes
This is a fixed up and cleaned up replacement for genirq-msi-fixes.patch,
which should solve the i386 4KSTACKS problem.  I also added Ben's idea of
pushing the __do_IRQ() check into generic_handle_irq().

I booted this with MSI enabled, but i only have MSI devices, not MSI-X
devices.  I'd still expect MSI-X to work now.

irqchip migration helper: call __do_IRQ() if a descriptor is attached to an
irqtype-style controller.  This also fixes MSI-X IRQ handling on i386 and
x86_64.

d1bef4ed5f [PATCH] genirq: rename desc->handler to desc->chip
This patch-queue improves the generic IRQ layer to be truly generic, by adding
various abstractions and features to it, without impacting existing
functionality.

While the queue can be best described as "fix and improve everything in the
generic IRQ layer that we could think of", and thus it consists of many
smaller features and lots of cleanups, the one feature that stands out most is
the new 'irq chip' abstraction.

The irq-chip abstraction is about describing and coding and IRQ controller
driver by mapping its raw hardware capabilities [and quirks, if needed] in a
straightforward way, without having to think about "IRQ flow"
(level/edge/etc.) type of details.

This stands in contrast with the current 'irq-type' model of genirq
architectures, which 'mixes' raw hardware capabilities with 'flow' details.
The patchset supports both types of irq controller designs at once, and
converts i386 and x86_64 to the new irq-chip design.

As a bonus side-effect of the irq-chip approach, chained interrupt controllers
(master/slave PIC constructs, etc.) are now supported by design as well.

The end result of this patchset intends to be simpler architecture-level code
and more consolidation between architectures.

We reused many bits of code and many concepts from Russell King's ARM IRQ
layer, the merging of which was one of the motivations for this patchset.

This patch:

rename desc->handler to desc->chip.

Originally i did not want to do this, because it's a big patch.  But having
both "desc->handler", "desc->handle_irq" and "action->handler" caused a
large degree of confusion and made the code appear alot less clean than it
truly is.

I have also attempted a dual approach as well by introducing a
desc->chip alias - but that just wasnt robust enough and broke
frequently.

So lets get over with this quickly.  The conversion was done automatically
via scripts and converts all the code in the kernel.

This renaming patch is the first one amongst the patches, so that the
remaining patches can stay flexible and can be merged and split up
without having some big monolithic patch act as a merge barrier.
