The idea is to fully construct the device register and interrupt values into these of_device objects, and convert all of SBUS, EBUS, ISA drivers to use this new stuff. Much ideas and code taken from Ben H.'s powerpc work. Signed-off-by:David S. Miller <davem@davemloft.net>

Totally unused. We need to traverse the list of global IRQ translaters, so storing it in the per-bus structures was useless. Signed-off-by: -

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.

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.

Thankfully, these dummy function calls are no longer required to avoid warnings - if they weren't eliminated as dead code but accidentially executed there would be a guaranteed NULL dereference. Signed-off-by:

Memory hotplug code of i386 adds memory to only highmem. So, if CONFIG_HIGHMEM is not set, CONFIG_MEMORY_HOTPLUG shouldn't be set. Otherwise, it causes compile error. In addition, many architecture can't use memory hotplug feature yet. So, I introduce CONFIG_ARCH_ENABLE_MEMORY_HOTPLUG. Signed-off-by:
