I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that. We'll find out anything that got broken and fix it.. * tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system: (38 commits) Delete all instances of asm/system.h Remove all #inclusions of asm/system.h Add #includes needed to permit the removal of asm/system.h Move all declarations of free_initmem() to linux/mm.h Disintegrate asm/system.h for OpenRISC Split arch_align_stack() out from asm-generic/system.h Split the switch_to() wrapper out of asm-generic/system.h Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h Create asm-generic/barrier.h Make asm-generic/cmpxchg.h #include asm-generic/cmpxchg-local.h Disintegrate asm/system.h for Xtensa Disintegrate asm/system.h for Unicore32 [based on ver #3, changed by gxt] Disintegrate asm/system.h for Tile Disintegrate asm/system.h for Sparc Disintegrate asm/system.h for SH Disintegrate asm/system.h for Score Disintegrate asm/system.h for S390 Disintegrate asm/system.h for PowerPC Disintegrate asm/system.h for PA-RISC Disintegrate asm/system.h for MN10300 ...

Essentially: - as we no longer support any other Acorn platforms other than RiscPC anymore, we can collect all that code into mach-rpc. - convert Acorn expansion card stuff to use IRQ allocation functions, and get rid of NO_IRQ from there. - cleanups to the ebsa110 platform to move some private stuff out of its header files. - large amount of SA11x0 updates: - conversion of private DMA implementation to DMA engine support (this actually gives us greater flexibility in drivers over the old API.) - re-worked ucb1x00 updates - convert to genirq, remove sa11x0 dependencies, fix various minor issues - move platform specific sa11x0 framebuffer data into platform files in arch/arm instead of keeping this in the driver itself - update sa11x0 IrDA driver for DMA engine, and allow it to use DMA for SIR transmissions as well as FIR - rework sa1111 support for genirq, and irq allocation - fix sa1111 IRQ support so it works again - use sparse IRQ support After this, I have one more pull request remaining from my current set, which I think is going to be the most problematical as it generates 8 conflicts."

| | * | | | ARM: sa1111: provide a generic way to prevent devices from registeringRussell King2012-03-243-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some platforms don't want certain devices to be registered, because, eg, the interface is not wired. Provide a way for platforms to prevent various devices from being registered via a devid bitmask in the platform data.

Create the neponset platform device in assabet.c, where we don't have to wrap it with machine_is_assabet() stuff. We also create this device dynamically rather than keeping it as a static device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Suspend and resume in the _noirq state, so that we're saving the state of the modem control signals as late as possible, and restoring them as early as possible. There's nothing to do in thaw/poweroff methods as we've already saved the necessary state. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the necessary allocation/freeing functionality to support sparse IRQs with the Neponset device. On non-sparse IRQ platforms, this allows us to dynamically allocate from within the available IRQ number space. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

It used to be that simple IRQs did not need an IRQ chip. This is no longer the case, and genirq barfs in irq_set_handler(). Fix this by introducing a dummy no-op chip, and registering it along with the flow handler. Neponset IRQs really don't have any masking ability - all we have is a status register to allow us to decode the source, and a three input OR gate inside a CPLD.

If GPIO27 is left as an input, it will float around mid-supply, which for CMOS inputs is the worst place for a pin to be. Ensure that this pin is driven.
