Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq updates from Thomas Gleixner:
"The irq departement delivers:
- a cleanup series to get rid of mindlessly copied code.
- another bunch of new pointlessly different interrupt chip drivers.
Adding homebrewn irq chips (and timers) to SoCs must provide a
value add which is beyond the imagination of mere mortals.
- the usual SoC irq controller updates, IOW my second cat herding
project"

irqchip: add irq-omap-intc.h header
OMAP INTC irqchip driver will be moved under drivers/irqchip/ soon but we still have a dependency with mach-omap2 when it comes to idle functions. In order to make it easy to share those function prototypes with OMAP PM code, we introduce this new header. To avoid modifying several board-files and some of the PM-related code, we just include the new header from common.h which was already included by all users of IRQ-related PM code.

irqchip: gic: Preserve gic V2 bypass bits in cpu ctrl register
This change is made to preserve the GIC v2 bypass bits in the GIC_CPU_CTRL register (also known as the GICC_CTLR register in spec). This code will preserve all bits configured by the bootloader regarding v2 bypass group bits. In the X-Gene platform, the bypass functionality is not used and bypass bits should not be changed by the kernel gic code as it could lead to incorrect behavior.

arm64: gicv3: Allow GICv3 compilation with older binutils
GICv3 introduces new system registers accessible with the full msr/mrs syntax (e.g. mrs x0, Sop0_op1_CRm_CRn_op2). However, only recent binutils understand the new syntax. This patch introduces msr_s/mrs_s assembly macros which generate the equivalent instructions above and converts the existing GICv3 code (both drivers/irqchip/ and arch/arm64/kernel/).

irqchip: gic-v3: Initial support for GICv3
The Generic Interrupt Controller (version 3) offers services that are similar to GICv2, with a number of additional features: - Affinity routing based on the CPU MPIDR (ARE) - System register for the CPU interfaces (SRE) - Support for more that 8 CPUs - Locality-specific Peripheral Interrupts (LPIs) - Interrupt Translation Services (ITS) This patch adds preliminary support for GICv3 with ARE and SRE, non-secure mode only. It relies on higher exception levels to grant ARE and SRE access. Support for LPI and ITS will be added at a later time.

irqchip: support cascaded VICs
This adds support for a VIC to be cascaded off another IRQ. On the Integrator/AP logical module IM-PD1 there is a VIC cascaded off the central FPGA IRQ controller so this is needed for that to work out. In order for the plug-in board to be able to register all the devices with their IRQs relative to the offset of the base obtained for the cascaded VIC, the base IRQ number is passed back to the caller.

DRIVERS: IRQCHIP: CROSSBAR: Add support for Crossbar IP
Some socs have a large number of interrupts requests to service the needs of its many peripherals and subsystems. All of the interrupt lines from the subsystems are not needed at the same time, so they have to be muxed to the irq-controller appropriately. In such places a interrupt controllers are preceded by an CROSSBAR that provides flexibility in muxing the device requests to the controller inputs. This driver takes care a allocating a free irq and then configuring the crossbar IP as a part of the mpu's irqchip callbacks. crossbar_init should be called right before the irqchip_init, so that it is setup to handle the irqchip callbacks.

DRIVERS: IRQCHIP: IRQ-GIC: Add support for routable irqs
In some socs the gic can be preceded by a crossbar IP which routes the peripheral interrupts to the gic inputs. The peripheral interrupts are associated with a fixed crossbar input line and the crossbar routes that to one of the free gic input line. The DT entries for peripherals provides the fixed crossbar input line as its interrupt number and the mapping code should associate this with a free gic input line. This patch adds the support inside the gic irqchip to handle such routable irqs. The routable irqs are registered in a linear domain. The registered routable domain's callback should be implemented to get a free irq and to configure the IP to route it.

Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King:
"Included in this series are:
1. BE8 (modern big endian) changes for ARM from Ben Dooks
2. big.Little support from Nicolas Pitre and Dave Martin
3. support for LPAE systems with all system memory above 4GB
4. Perf updates from Will Deacon
5. Additional prefetching and other performance improvements from Will.
6. Neon-optimised AES implementation fro Ard.
7. A number of smaller fixes scattered around the place.
There is a rather horrid merge conflict in tools/perf - I was never
notified of the conflict because it originally occurred between Will's
tree and other stuff. Consequently I have a resolution which Will
forwarded me, which I'll forward on immediately after sending this
mail.
The other notable thing is I'm expecting some build breakage in the
crypto stuff on ARM only with Ard's AES patches. These were merged
into a stable git branch which others had already pulled, so there's
little I can do about this. The problem is caused because these
patches have a dependency on some code in the crypto git tree - I
tried requesting a branch I can pull to resolve these, and all I got
each time from the crypto people was "we'll revert our patches then"
which would only make things worse since I still don't have the
dependent patches. I've no idea what's going on there or how to
resolve that, and since I can't split these patches from the rest of
this pull request, I'm rather stuck with pushing this as-is or
reverting Ard's patches.
Since it should "come out in the wash" I've left them in - the only
build problems they seem to cause at the moment are with randconfigs,
and since it's a new feature anyway. However, if by -rc1 the
dependencies aren't in, I think it'd be best to revert Ard's patches"
I resolved the perf conflict roughly as per the patch sent by Russell,
but there may be some differences. Any errors are likely mine. Let's
see how the crypto issues work out..

drivers: irq-chip: irq-gic: introduce gic_cpu_if_down()
When processors are about to hit low power states, the assertion of standbywfi signal, triggered by the wfi instruction, is essential to entering low power modes. If an IRQ is pending on the processor at the time wfi is issued, the wfi instruction completes and the processor restarts execution without asserting the standbywfi signal. Depending on the platform power controller HW this behaviour can be acceptable or not; if this behaviour must be prevented software should be provided with a way to disable the routing of interrupts to the core IRQ pins. On systems where raw GIC distributor interrupts are connected to the power controller as wake-up events (hence the power controller still senses IRQs and can wake up cores upon IRQ pending), the GIC CPU interface can be disabled on power down, so that the GIC CPU IF output is gated and wfi cannot complete, thereby preventing the standbywfi issue. This patch adds a simple function to the GIC driver that allows to disable the GIC CPU IF from power down procedures.

ARM: bL_switcher: do not hardcode GIC IDs in the code
Currently, GIC IDs are hardcoded making the code dependent on the 4+4 b.L configuration. Let's allow for GIC IDs to be discovered upon switcher initialization to support other b.L configurations such as the 1+1 one, or 2+3 as on the VExpress TC2. Signed-off-by: Nicolas Pitre <nico@linaro.org> |

ARM: gic: add CPU migration support
This is required by the big.LITTLE switcher code. The gic_migrate_target() changes the CPU interface mapping for the current CPU to redirect SGIs to the specified interface, and it also updates the target CPU for each interrupts to that CPU interface if they were targeting the current interface. Finally, pending SGIs for the current CPU are forwarded to the new interface. Because Linux does not use it, the SGI source information for the forwarded SGIs is not preserved. Neither is the source information for the SGIs sent by the current CPU to other CPUs adjusted to match the new CPU interface mapping. The required registers are banked so only the target CPU could do it. Signed-off-by: Nicolas Pitre <nico@linaro.org> |

metag: Internal and external irqchips
Meta core internal interrupts (from HWSTATMETA and friends) are vectored onto the TR1 core trigger for the current thread. This is demultiplexed in irq-metag.c to individual Linux IRQs for each internal interrupt. External SoC interrupts (from HWSTATEXT and friends) are vectored onto the TR2 core trigger for the current thread. This is demultiplexed in irq-metag-ext.c to individual Linux IRQs for each external SoC interrupt. The external irqchip has devicetree bindings for configuring the number of irq banks and the type of masking available.

ARM: plat-versatile: move FPGA irq driver to drivers/irqchip
This moves the Versatile FPGA interrupt controller driver, used in the Integrator/AP, Integrator/CP and some Versatile boards, out of arch/arm/plat-versatile and down to drivers/irqchip where we have consensus that such drivers belong. The header file is consequently moved to <linux/platform_data/irq-versatile-fpga.h>. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> |

ARM: bcm2835: add interrupt controller driver
The BCM2835 contains a custom interrupt controller, which supports 72 interrupt sources using a 2-level register scheme. The interrupt controller, or the HW block containing it, is referred to occasionally as "armctrl" in the SoC documentation, hence the symbol naming in the code. This patch was extracted from git://github.com/lp0/linux.git branch rpi-split as of 2012/09/08, and modified as follows: * s/bcm2708/bcm2835/. * Modified device tree vendor prefix. * Moved implementation to drivers/irchip/. * Added devicetree documentation, and hence removed list of IRQs from bcm2835.dtsi. * Changed shift in MAKE_HWIRQ() and HWIRQ_BANK() from 8 to 5 to reduce the size of the hwirq space, and pass the total size of the hwirq space to irq_domain_add_linear(), rather than just the number of valid hwirqs; the two are different due to the hwirq space being sparse. * Added the interrupt controller DT node to the top-level of the DT, rather than nesting it inside a /axi node. Hence, changed the reg value since /axi had a ranges property. This seems simpler to me, but I'm not sure if everyone will like this change or not. * Don't set struct irq_domain_ops.map = irq_domain_simple_map, hence removing the need to patch include/linux/irqdomain.h or kernel/irq/irqdomain.c. * Simplified armctrl_of_init() using of_iomap(). * Removed unused IS_VALID_BANK()/IS_VALID_IRQ() macros. * Renamed armctrl_handle_irq() to prevent possible symbol clashes. * Made armctrl_of_init() static. * Removed comment "Each bank is registered as a separate interrupt controller" since this is no longer true. * Removed FSF address from license header. * Added my name to copyright header.
