2011-11-21ARM: restart: remove poodle restart handlerRussell King
The poodle restart handler was added in 74617fb6b8 (3593/1: Add reboot and shutdown handlers for Zaurus handhelds), and at that time it was necessary to deal with the RCSR register. This commit also forced all restarts to use the 'hard' restart method. In dc38e2ad53 (pxa: Fix RCSR handling), the RCSR handling was removed, leaving just the forcing to use a 'hard' restart. As hard restarts are the default (in the absense of a reboot= command line argument), this seems pointless. In any case, Richard Purdie says: > From what I remember that hardware either always reboots or always > halts. I think the option was therefore left hardcoded to make it clear > it wasn't expected to work. Later Zaurii models could do either but > required some manual poking of registers to make it happen iirc. > > Regardless, you can probably clean this up as you suggest now. So, lets remove the unnecessary interception and rely on the default restart mode.

2011-11-21ARM: restart: only perform setup for restart when soft-restartingRussell King
We only need to set the system up for a soft-restart if we're going to be doing a soft-restart. Provide a new function (soft_restart()) which does the setup and final call for this, and make platforms use it. Eliminate the call to setup_restart() from the default handler. This means that platforms arch_reset() function is no longer called with the page tables prepared for a soft-restart, and caches will still be enabled.

2011-11-15ARM: Make global handler and CONFIG_MULTI_IRQ_HANDLER mutually exclusiveMarc Zyngier
Even when CONFIG_MULTI_IRQ_HANDLER is selected, the core code requires the arch_irq_handler_default macro to be defined as a fallback. It turns out nobody is using that particular feature as both PXA and shmobile have all their machine descriptors populated with the interrupt handler, leaving unused code (or empty macros) in their entry-macro.S file just to be able to compile entry-armv.S. Make CONFIG_MULTI_IRQ_HANDLER exclusive wrt arch_irq_handler_default, which allows to remove one test from the hot path. Also cleanup both PXA and shmobile entry-macro.S.

2011-11-15ARM: gic: allow GIC to support non-banked setupsMarc Zyngier
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).
