2010-03-19ARM: 5962/1: ux500: move system timer to cpu fileRabin Vincent
There is nothing board-specific about the system timer, so move it to the CPU file.

2010-03-19ARM: 5972/1: nomadik-gpio: convert to platform driverRabin Vincent
On the U8500 platform there are four GPIO blocks, each with a 4K address space, including the peripheral identification. However, each of these blocks have a varying number of banks, each of which have 32 GPIOs and an interrupt line. The current nomadik-gpio driver implementation can handle each of these sub-banks easily with one instance each, but cannot as-is be hooked up to them because it is an AMBA driver and it expects to see a peripheral with the appropriate peripheral ids but having only one bank and only one interrupt. Solve this by converting the driver to a platform driver.

2010-03-19ARM: 5971/1: nomadik-gpio: mask/ack/unmask the parent irqRabin Vincent
Since we register as a chained handler, we need to take care of acking the parent irq. Current code had the acking disabled because just acking the interrupt disables it on some interrupt controllers (like the VIC used on Nomadik). However, not acking at all is incorrect because interrupt controllers like the GIC need an EOI indication, which is done in the ack routine. Solve this by maskacking and unmasking it appropriately, similar to how handle_level_irq operates.

2010-03-19ARM: 5969/1: nomadik: move gpio to plat-nomadikRabin Vincent
Move the Nomadik GPIO driver to plat-nomadik so that it can also be used on the Ux500 platform. The mach-nomadik include/mach/gpio.h is replaced by one that includes the one now in plat-nomadik, so that code doesn't need to include the one in plat specifically, and can instead use <linux/gpio.h> as usual.

2010-03-13ARM: 5960/1: ARM: perf-events: fix v7 event selection maskWill Deacon
The event selection mask for ARMv7 cores [ARMV7_EVTSEL_MASK] is incorrectly set to 0x7f. This means that the top bit of an event ID is ignored, so counting branch misses (id=0x10) and ISBs (id=0x90) give the same results. This patch sets the event selection mask to the correct value of 0xff.

2010-03-13ARM: 5959/1: ARM: perf-events: request PMU interrupts with IRQF_NOBALANCINGWill Deacon
If IRQ balancing is used on a multicore ARM system, PMU interrupt lines may be relocated onto CPUs other than the one causing the counter overflow. This can result in misattribution of events to the wrong core and, in the case that the CPU handling the interrupt has not experience counter overflow, the interrupt can be disabled because the handler returns IRQ_NONE. This patch adds the IRQF_NOBALANCING flag to the request_irq call in perf_events.c.

2010-03-13ARM: 5988/1: pgprot_dmacoherent() for non-mmu buildsGreg Ungerer
Commit 26a26d329688ab018e068b412b03d43d7c299f0a ("dma-mapping: switch ARMv7 DMA mappings to retain 'memory' attribute") added a new macro, pgprot_dmacoherent(), to correctly map DMA memory. The non-mmu pgtable support code also needs to implement this macro, otherwise when compiling you get: CC arch/arm/mm/dma-mapping.o arch/arm/mm/dma-mapping.c: In function 'dma_alloc_coherent': arch/arm/mm/dma-mapping.c:320: error: implicit declaration of function 'pgprot_dmacoherent' arch/arm/mm/dma-mapping.c:320: error: 'pgprot_kernel' undeclared (first use in this function) arch/arm/mm/dma-mapping.c:320: error: (Each undeclared identifier is reported only once arch/arm/mm/dma-mapping.c:320: error: for each function it appears in.)

2010-03-13ARM: 5987/1: fix warning in kernel/elfcore.c from ARM's elf.hMikael Pettersson
2.6.34-rc1 added kernel/elfcore.c which includes <asm/elf.h>. On ARM, this results in: In file included from include/linux/elf.h:7, from kernel/elfcore.c:1: /tmp/linux-2.6.34-rc1/arch/arm/include/asm/elf.h:101: warning: 'struct task_struct' declared inside parameter list /tmp/linux-2.6.34-rc1/arch/arm/include/asm/elf.h:101: warning: its scope is only this definition or declaration, which is probably not what you want Including <linux/sched.h> seems a bit heavyweight, so this patch just adds a tentative declaration of struct task_struct in <asm/elf.h>.

2010-03-13ARM: 5986/1: at91sam9g20-ek: Correct braces in I2C registration codeRob Alley
The change introduced in patch 5596/1 used incorrect bracing which resulted in the AT24 EEPROM no longer being registered. This patch corrects the bracing and allows both the WM8731 audio device and AT24 EEPROM device to be registered.

2010-03-13ARM: 5985/2: ARM: Fix Samsung build after "ARM: Eliminate decompressor ↵Mark Brown
-Dstatic= PIC hack" Commit 5de813b6 (ARM: Eliminate decompressor -Dstatic= PIC hack) among other things changed the declared type of the error() function to an extern, conflicting with the forward declartion in the Samsung plat/uncompress.h which appears to have been relying on the static being defined away, causing build failures since error() ends up with a GOT relocation but the linker script discards all GOT relocated data and functions: arch/arm/boot/compressed/decompress.o: In function `gunzip': /home/broonie/git/linux-2.6/arch/arm/boot/compressed/../../../../lib/decompress_ +inflate.c:68: undefined reference to `error' and so on. Fix this by moving the declaration into uncompress/misc.c where it is shared with the rest of the code, correcting the definition as we go.
