2014-03-26gpio: add IRQ chip helpers in gpiolibLinus Walleij
This provides a function gpiochip_irqchip_add() to set up an irqchip for a GPIO controller, and a function gpiochip_set_chained_irqchip() to chain it to a parent irqchip. Most GPIOs are of the type where a number of lines form a cascaded interrupt controller chained onto the primary system interrupt controller (or further down the chain) so let's add this helper and factor the code to request the lines to be used as IRQs, the .to_irq() function and the irqdomain into the core as well.

2014-03-26ARC: switch to generic ENTRY/END assembler annotationsVineet Gupta
With commit 9df62f054406 "arch: use ASM_NL instead of ';'" the generic macros can handle the arch specific newline quirk. Hence we can get rid of ARC asm macros and use the "C" style macros. Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

2014-03-26mtd: nand: fix mention to CONFIG_MTD_NAND_ECC_BCHErico Nunes
Mention to CONFIG_MTD_ECC_BCH in the warning message can be confusing as this doesn't match the exact name of the configuration option. This warning showed up once to me when I was starting to set up BCH. After checking my .config file, it took a moment before realizing it is CONFIG_MTD_NAND_ECC_BCH instead of CONFIG_MTD_ECC_BCH.

2014-03-25mtd: devices: elm: configure parallel channels based on ecc_stepsPekon Gupta
ELM hardware can process up to maximum of 8 hannels in parallel for ECC error detection. Currently the number of channels getting configured for processing is static determined by macro ERROR_VECTOR_MAX. However, the actual number of channels that need to be processed is the ECC step number. This patch just avoids configuring extra unused channels.

2014-03-25mtd: devices: elm: check for hardware engine's design constraintsPekon Gupta
ELM hardware engine is used by BCH ecc-schemes for detecting and locating ECC errors. This patch adds the following checks for ELM hardware engine: - ELM internal buffers are of 1K, so it cannot process data with ecc-step-size > 1K. - ELM engine can execute upto maximum of 8 threads in parallel, so in *page-mode* (when complete page is processed in single iteration), ELM cannot support ecc-steps > 8.

2014-03-26drm/nouveau/bios: fetch the vbios from PROM using only aligned 32-bit accessesMartin Peres
Other kind of accesses are unreliable on Kepler cards. As advised by NVIDIA, let's only use 32-bit accesses to fetch the vbios from PROM. This fixes vbios fetching on my nve7 which failed in certain specific conditions. I suggest we Cc stable, for all kernels they still maintain after the big rewrite.

2014-03-26drm/nouveau: fix small thinko in vblank timestamping.Mario Kleiner
*hpos horizontal scanout position doesn't need to be corrected to count the pixels between hactive end and htotal negative. That is only needed for *vpos to count lines until end of vblank for the vblank timestamping. Use hpos as is without correction. Removes occassional spikes in timestamps of up to 1 scanline duration, thereby improves accuracy to about +/- 2 usecs instead of +/- 12 usecs, wrt. true onset time as measured with high precision equipment on NV-A5.
