This fixes up the simplified multi-evt handling when sparseirq support is enabled. While vectors are redirected through the single unique masking source, each one of the redirected vectors still requires its own backing irq_desc, which needs to be manually allocated in the sparseirq case.

This patch changes the way in which "multi-evt" interrups are handled. The intc_evt2irq_table and related intc_evt2irq() have been removed and the "redirecting" handler is installed for the coupled interrupts. Thanks to that the do_IRQ() function don't have to use another level of indirection for all the interrupts...

It is possible for the CPU to re-enable it's interrupt block bit before the write to the interrupt controller has actually masked out the external interupt at the controller. We get around this by reading back from the interrupt controller which will ensure the write has happened.

irq_to_desc_alloc_cpu() has been renamed to irq_to_desc_alloc_node() in -next, but as we can not presently enable SPARSE_IRQ without the early irq_desc alloc patch, protect it with an ifdef until the interface has settled and we are ready to enable it system-wide.

This hooks in irq_to_desc_alloc_cpu() to the necessary code paths in the intc and ipr controller registration paths. As these are the primary call paths for all SH CPUs, this alone will make all CPUs sparse IRQ ready. There is the added benefit now that each CPU contains specific IPR and INTC tables, so only the vectors with interrupt sources backing them will ever see an irq_desc instantiation. This effectively packs irq_desc down to match the CPU, rather than padding NR_IRQS out to cover the valid vector range. Boards with extra sources will still have to fiddle with the nr_irqs setting, but they can continue doing so through the machvec as before. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Add set_irq_wake() support to intc using sysdev and suspend. The intc controllers are put on a list at registration time and registered as sysdev devices later on during the boot. The sysdev class suspend callback is used to find irqs with wakeup enabled belonging to our intc controller. Such irqs are simply enabled so wakeup interrupts may reach the cpu.

Modify the intc code to install a disable callback. The current solution without a disable callback results in use of the generic default_disable() function. This function is a no-op so suspend_device_irqs() will not disable any intc interrupts at suspend time without this patch. Also, install enable and shutdown callbacks while at it.

Instead of keeping the single vector -> single linux irq mapping we extend the intc code to support merging of vectors to a single linux irq. This helps processors such as sh7750, sh7780 and sh7785 which have more vectors than masking ability. With this patch in place we can modify the intc tables to use one irq per maskable irq source. Please note the following: - If multiple vectors share the same enum then only the first vector will be available as a linux irq. - Drivers may need to be rewritten to get pending irq source from the hardware block instead of irq number. This patch together with the sh7785 specific intc tables solves DMA controller irq issues related to buggy interrupt masking.

This patch updates the maple bus to support asynchronous block reads and writes as well as generally improving the quality of the code and supporting concurrency (all needed to support the Dreamcast visual memory unit - a driver will also be posted for that). Changes in the bus driver necessitate some changes in the two maple bus input drivers that are currently in mainline. As well as supporting block reads and writes this code clean up removes some poor handling of locks, uses an atomic status variable to serialise access to devices and more robusly handles the general performance problems of the bus.

The maple bus driver that went into the kernel mainline in September 2007 contained some bugs which were revealed by the update of the kobj code for the current release series. Unfortunately those bugs also helped ensure maple devices were properly detected. This patch (against the current git) now ensures that devices are properly detected again. (A previous attempt to fix this by delaying initialisation only partially fixed this - as became apparent when the bus was fully loaded) Signed-off-by: NAdrian McMenamin <adrian@mcmen.demon.co.uk> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

The Maple bus is SEGA's proprietary serial bus for peripherals (keyboard, mouse, controller etc). The bus is capable of some (limited) hotplugging and operates at up to 2 M/bits. Drivers of one sort or another existed/exist for 2.4 and a rudimentary port, which didn't support the 2.6 device driver model was also in existence. This driver - for the bus logic itself and for the keyboard (other drivers will follow) are based on the code and concepts of those old drivers but have lots of completely rewritten parts. I have the maple bus code as a built in now as that seems the sane and rational way to handle something like that - you either want the bus or you don't.

This extends the API somewhat to allow for platform-specific VCR reading and writing. Some platforms (like SH4-202) implement the VCR in a split VCRL and VCRH, but end up being in reverse order or have other quirks that need to be dealt with, so we add a set of superhyway_ops per-bus to accomodate this. We also have to extend the per-device resources somewhat, as some devices now conveniently split control and data blocks. So we allow a platform to register its set of SuperHyway devices via superhyway_add_devices() with the control block always ordered as the first resource (as this is the one that userspace cares about).

I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
