[ARM] Separate VIC (vectored interrupt controller) support from Versatile Other machines may wish to make use of the VIC support code, so move it to arch/arm/common. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

config ARM_GIC
ARM: gic: add irq_domain support Convert the gic interrupt controller to use irq domains in preparation for device-tree binding and MULTI_IRQ. This allows for translation between GIC interrupt IDs and Linux irq numbers. The meaning of irq_offset has changed. It now is just the number of skipped GIC interrupt IDs for the controller. It will be 16 for primary GIC and 32 for secondary GICs.

Linux-2.6.12-rc2 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!

bool
ARM: gic: allow GIC to support non-banked setups The GIC support code is heavily using the fact that hardware implementations are exposing banked registers. Unfortunately, it looks like at least one GIC implementation (EXYNOS) offers both the distributor and the CPU interfaces at different addresses, depending on the CPU. This problem is solved by allowing the distributor and CPU interface addresses to be per-cpu variables for the platforms that require it. The EXYNOS code is updated not to mess with the GIC internals while handling interrupts, and struct gic_chip_data is back to being private. The DT binding for the gic is updated to allow an optional "cpu-offset" value, which is used to compute the various base addresses. Finally, a new config option (GIC_NON_BANKED) is used to control this feature, so the overhead is only present on kernels compiled with support for EXYNOS. Tested on Origen (EXYNOS4) and Panda (OMAP4).

ARM: vic: device tree binding This adds a device tree binding for the VIC based on the of_irq_init() support. This adds an irqdomain to the vic and always registers all vics in the static vic array rather than for pm only to keep track of the irq domain. struct irq_data::hwirq is used where appropriate rather than runtime masking. v3: - include linux/export.h for THIS_MODULE v2: - use irq_domain_simple_ops - remove stub implementation of vic_of_init for !CONFIG_OF - Make VIC select IRQ_DOMAIN Reviewed-by: Rob Herring <robherring2@gmail.com> Reviewed-by: Grant Likely <grant.likely@secretlab.ca> Tested-by: Thomas Abraham <thomas.abraham@linaro.org> Signed-off-by: Jamie Iles <jamie@jamieiles.com>

[ARM] VIC: Add power management device Add power management support to the VIC by registering each VIC as a system device to get suspend/resume events going.
