2011-12-01arm/imx: fix irq_base for gpioShawn Guo
When gpio core dynamically allocate gpio number for a port, it starts from the end of the total range, 0 ~ ARCH_NR_GPIOS. That said, the earlier a port gets probed, the bigger gpio number it gets assigned. To match this, the irq_base for gpio should be assigned from 'MXC_GPIO_IRQ_START + ARCH_NR_GPIOS' decreasingly.

2011-12-01arm/imx: fix return type of callback passed to of_irq_init()Shawn Guo
The of_irq_init() expects the callback passed by .data of of_device_id return 'int' instead of 'void'. This patch fixes it to have irq_init_cb() return the correct value, and in turn have the secondary interrupt controller (gpio in this case) initialized properly and also eliminate the error message 'of_irq_init: children remain, but no parents' which was overlooked before.

2011-11-30ARM: 7181/1: Restrict kprobes probing SWP instructions to ARMv5 and belowJon Medhurst (Tixy)
The SWP instruction is deprecated on ARMv6 and with ARMv7 it will be UNDEFINED when CONFIG_SWP_EMULATE is selected. In this case, probing a SWP instruction will cause an oops when the kprobes emulation code executes an undefined instruction. As the SWP instruction should be rare or non-existent in kernels for ARMv6 and later, we can simply avoid these problems by not allowing probing of these.

2011-11-30ARM: 7180/1: Change kprobes testcase with unpredictable STRD instructionJon Medhurst (Tixy)
There is a kprobes testcase for the instruction "strd r2, [r3], r4". This has unpredictable behaviour as it uses r3 for register writeback addressing and also stores it to memory. On a cortex A9, this testcase would fail because the instruction writes the updated value of r3 to memory, whereas the kprobes emulation code writes the original value. Fix this by changing testcase to used r5 instead of r3.

2011-11-26ARM: 7177/1: GIC: avoid skipping non-existent PPIs in irq_start calculationWill Deacon
Commit 4294f8baa ("ARM: gic: add irq_domain support") defines irq_start as irq_start = (irq_start & ~31) + 16; On a platform with a GIC and a CPU without PPIs, this results in irq_start being off by 16. This patch fixes gic_init so that we only carve out a PPI space when PPIs exist for the GIC being initialised.

2011-11-26ARM: 7176/1: cpu_pm: register GIC PM notifier only onceMarc Zyngier
When multiple GICs exist on a platform (RealView PB1176/11MP), we must make sure the PM notifier block is only registered once, otherwise we end up corrupting the PM notifier list. The fix is to only register the notifier when initializing the first GIC, as the power management functions seem to iterate over all the registered GICs. Tested on PB11MP and PB1176.

2011-11-26ARM: 7174/1: Fix build error in kprobes test code on Thumb2 kernelsJon Medhurst
When compiling kprobes-test-thumb.c an error like below may occur: /tmp/ccKcuJcG.s:19179: Error: offset out of range This is caused by the compiler underestimating the size of the inline assembler instructions containing ".space 0x1000" and failing to spill the literal pool in time to prevent the generation of PC relative load instruction with invalid offsets. The fix implemented by this patch is to replace a single large .space directive by a number of 4 byte .space's. This requires splitting the macros which generate test cases for branch instructions into two forms: one with, and one without support for inserting extra code between branch and target.

2011-11-26ARM: 7171/1: unwind: add unwind directives to bitops assembly macrosWill Deacon
The bitops functions (e.g. _test_and_set_bit) on ARM do not have unwind annotations and therefore the kernel cannot backtrace out of them on a fatal error (for example, NULL pointer dereference). This patch annotates the bitops assembly macros with UNWIND annotations so that we can produce a meaningful backtrace on error. Callers of the macros are modified to pass their function name as a macro parameter, enforcing that the macros are used as standalone function implementations.

2011-11-23ARM: OMAP: hwmod: Fix the addr space, irq, dma count APIssricharan
The address spaces, irqs and dma reqs count APIs return the number of corresponding entries in a hwmod including a additional null value or a -1 terminator in the structure introduced recently. More information here: - 212738a4: omap_hwmod: use a terminator record with omap_hwmod_mpu_irqs arrays - 78183f3f: omap_hwmod: use a null structure record to terminate omap_hwmod_addr_space arrays - bc614958: omap_hwmod: use a terminator record with omap_hwmod_dma_info arrays The issue with irqs and dma info was originally reported by Benoit Cousson. The devices which have multiple hwmods and use device_build_ss are broken with this, as their resources are populated with a extra null value, subsequently the probe fails. So fix the API not to include the array terminator in the count.
