2012-03-25mmc: sdhci: Add platform suspend/resume hooks.Chris Ball
Some platforms require saving/restoring registers across suspend/resume; this hook allows them to do that inside their driver. Signed-off-by: Chris Ball <cjb@laptop.org>
2012-03-25mmc: dw_mmc: Override blk_settings with platdata on IDMACJaehoon Chung
When use the IDMAC, we can also want to use the pdata->blk-setting. So if pdata->blk-setting is unset, use the default value. if not, use the pdata->blk-setting.

2012-03-25mmc: Support of PCI mode in the dw_mmc driverShashidhar Hiremath
Support of PCI mode for the dw_mmc driver. This Patch adds the support for the scenario where the Synopsys Designware IP is present on the PCI bus. The patch adds the minimal modifications necessary for the driver to work on PCI platform. Also added separate files for PCI and PLATFORM modes of operation.

2012-03-25ARM: 7343/1: sa11x0: convert to sparse IRQRussell King
Now that Neponset, UCB1x00 and SA1111 are all converted to use the IRQ allocation interfaces, we can enable sparse IRQ support for SA11x0 platforms.
2012-03-25ARM: 7342/2: sa1100: prepare for sparse irq conversionRob Herring
In preparation to convert SA1100 to sparse irq, set .nr_irqs for each machine and explicitly include mach/irqs.h as needed. Signed-off-by: Rob Herring <rob.herring@calxeda.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-25ARM: 7341/1: input: prepare jornada720 keyboard and ts for sa11x0 sparse irqRob Herring

2012-03-25ARM: 7340/1: rtc: sa1100: include mach/irqs.h instead of asm/irq.hRob Herring

2012-03-25ARM: sa11x0: remove unused DMA controller definitionsRussell King
Remove the new unused DMA controller definitions from mach/SA-1100.h. These are now private to the SA-11x0 DMA engine driver and contained within the driver. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-03-25ARM: sa11x0: remove old SoC private DMA driverRussell King
Now that all users are converted over to using the DMA engine API, we can get rid of the old platform dependent DMA driver. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2012-03-25ARM: pxa: use common IOMEM definitionRob Herring
pxa was missed in the moving of IOMEM to a common definition, so lots of IOMEM redefined warnings were introduced. So remove pxa IOMEM definition and fix all the fallout.

2012-03-25ARM: dma-mapping: convert ARCH_HAS_DMA_SET_COHERENT_MASK to kconfig symbolRob Herring
The only users of ARCH_HAS_DMA_SET_COHERENT_MASK are 2 ARM platforms: ixp4xx and pxa cm_x2xx. We've been getting lucky that the define is implicitly included before dma-mapping.h, but the removal of io.h broke things (c334bc1 ARM: make mach/io.h include optional). Since memory.h is the correct place, but no longer exists, convert the define to a kconfig entry.

2012-03-25net: add a truesize parameter to skb_add_rx_frag()Eric Dumazet
skb_add_rx_frag() API is misleading. Network skbs built with this helper can use uncharged kernel memory and eventually stress/crash machine in OOM.

2012-03-25um: Switch to large mcmodel on x86_64Richard Weinberger
x86_64 UML is unable to load modules if more than 504MiB of memory are used. This happens because on x86_64 the UML process has a quite high start address (typically around 0x6000000). If UML's memory is larger than 504MiB VMALLOC_START happens to be after 0x8000000. This is no problem unless one loads a module which was built with R_X86_64_32S relocations. Symbols with a location > 0x8000000 cannot be used with R_X86_64_32S To deal with this x86_64 UML has to be compiled with -mcmodel=large such that no R_X86_64_32S relocations are used.

2012-03-25um: Serve io_remap_pfn_range()Richard Weinberger

2012-03-25Introduce CONFIG_GENERIC_IORichard Weinberger
There are situations where CONFIG_HAS_IOMEM is too restrictive. For example CONFIG_MTD_NAND_NANDSIM depends on CONFIG_HAS_IOMEM but it works perfectly fine if an architecture without io memory just includes asm-generic/io.h or implements everything defined in it. UML is such a corner case. Signed-off-by: Richard Weinberger <richard@nod.at>

2012-03-25um: switch line.c tty drivers to dynamic device creationAl Viro
Current code doesn't update the symlinks in /sys/dev/char when we add/remove tty lines. Fixing that allows to stop messing with ->valid before the driver registration, which is a Good Thing(tm) - we shouldn't have it set before we really have the things set up and ready for line_open(). We need tty_driver available to call tty_{un,}register_device(), so we just stash a reference to it into struct line_driver.
