2010-10-29MIPS: Convert DMA to use dma-mapping-common.hDavid Daney
Use asm-generic/dma-mapping-common.h to handle all DMA mapping operations and establish a default get_dma_ops() that forwards all operations to the existing code. Augment dev_archdata to carry a pointer to the struct dma_map_ops, allowing DMA operations to be overridden on a per device basis. Currently this is never filled in, so the default dma_map_ops are used. A follow-on patch sets this for Octeon PCI devices. Also initialize the dma_debug system as it is now used if it is configured.

2010-10-29MIPS: Get rid of branches to .subsections.Ralf Baechle
It was a nice optimization - on paper at least. In practice it results in branches that may exceed the maximum legal range for a branch. We can fight that problem with -ffunction-sections but -ffunction-sections again is incompatible with -pg used by the function tracer. By rewriting the loop around all simple LL/SC blocks to C we reduce the amount of inline assembler and at the same time allow GCC to often fill the branch delay slots with something sensible or whatever else clever optimization it may have up in its sleeve. With this optimization gone we also no longer need -ffunction-sections, so drop it. This optimization was originally introduced in 2.6.21, commit 5999eca25c1fd4b9b9aca7833b04d10fe4bc877d (linux-mips.org) rsp. f65e4fa8e0c6022ad58dc88d1b11b12589ed7f9f (kernel.org).

2010-10-29omap4: pandaboard: fix up mmc card detect logicMenon, Nishanth
For MMC1 Controller, card detect interrupt source is twl6030 which is non-gpio. The card detect call back function provides card present/absent status by reading MMC Control register present on twl6030. This functionality was introduced in mfd tree on track to kernel.org Sync pandaboard to the same and make mmc work.

2010-10-29mfd: Adding twl6030 mmc card detect support for MMC1kishore kadiyala
Adding card detect callback function and card detect configuration function for MMC1 Controller on OMAP4. Card detect configuration function does initial configuration of the MMC Control & PullUp-PullDown registers of Phoenix. For MMC1 Controller, card detect interrupt source is twl6030 which is non-gpio. The card detect call back function provides card present/absent status by reading MMC Control register present on twl6030. Since OMAP4 doesn't use any GPIO line as used in OMAP3 for card detect, the suspend/resume initialization which was done in omap_hsmmc_gpio_init previously is moved to the probe thus making it generic for both OMAP3 & OMAP4.

2010-10-29ARM: mach-shmobile: ap4evb: Fix hotplug for SDHI1Arnd Hannemann
On AP4EVB the card detect pin of the top SD/MMC slot is not directly connected to the tmio/mmcif controller but to a GPIO pin, so polling needs to be done for SDHI1 and MMCIF in order to support hotplug for that slot. SHDI1 and MMCIF share that slot, and the used controller is selected by a DIP switch. This patch adds a helper function to check if a card is present in that particular slot, registers this function with SDHI1 and MMCIF and enables polling for SDHI1.

2010-10-27alpha: remove dma64_addr_t usageFUJITA Tomonori
dma_addr_t is always 64 bit on alpha. So let's use dma_addr_t instead.

2010-10-27mips: remove dma64_addr_t usageFUJITA Tomonori
dma64_addr_t looks pointless (at least there is no point that an architecture has the own dma64_addr_t typedef). dma_addr_t is set to 32 or 64 bits appropriately. You can use u64 at places where you know that 64 bit address is always necessary. Let's use u64 instead for mips.

You can use u64 at places where you know that 64 bit address is always necessary. Let's use u64 instead for sparc32. Looks like PCI654_REQUIRED_MASK or PCI64_ADR_BASE isn't used. They can be removed?

2010-10-27taskstats: use real microsecond granularity for CPU timesMichael Holzheu
The taskstats interface uses microsecond granularity for the user and system time values. The conversion from cputime to the taskstats values uses the cputime_to_msecs primitive which effectively limits the granularity to milliseconds. Add the cputime_to_usecs primitive for architectures that have better, more precise CPU time values. Remove cputime_to_msecs primitive because there are no more users left.

2010-10-27rapidio: add handling of redundant routesAlexandre Bounine
Detects RIO link to the already enumerated device and properly sets links between device objects. Changes to the enumeration/discovery logic: 1. Use Master Enable bit to signal end of the enumeration - agents may start their discovery process as soon as they see this bit set (Component Tag register was used before for this purpose). 2. Enumerator sets Component Tag (!= 0) immediately during device setup. This allows to identify the device if the redundant route exists in a RIO system.
