2010-03-06mc13783: rename mc13783_{{un,}mask,ack_irq} to have a mc13783_irq prefixUwe Kleine-König
In the source file group these functions together. The mc13783 header file provides fallback implementations for the old names to prevent build failures. When all users of the old names are fixed to use the new names these can go away.

This patch is setting some max_ variables for the IO elevator, so the elevator will put requests for large data blocks to the driver. This is critical for a) speed and b) wear leveling of the flash chip controller: Otherwise the controller will treat the SD card badly with millions of single 4 KByte write commands.

2010-03-06s3cmci: initialize default platform data no_wprotect and no_detect with 1Lars-Peter Clausen
If no platform_data was givin to the device it's going to use it's default platform data struct which has all fields initialized to zero. As a result the driver is going to try to request gpio0 both as write protect and card detect pin. Which of course will fail and makes the driver unusable Previously to the introduction of no_wprotect and no_detect the behavior was to assume that if no platform data was given there is no write protect or card detect pin. This patch restores that behavior.

2010-03-06sdio: introduce API for special power management featuresNicolas Pitre
This patch series provides the core changes needed to allow SDIO cards to remain powered and active while the host system is suspended, and let them wake up the host system when needed. This is used to implement wake-on-lan with SDIO wireless cards at the moment. Patches to add that support to the libertas driver will be posted separately. This patch: Some SDIO cards have the ability to keep on running autonomously when the host system is suspended, and wake it up when needed. This however requires that the host controller preserve power to the card, and configure itself appropriately for wake-up. There is however 4 layers of abstractions involved: the host controller driver, the MMC core code, the SDIO card management code, and the actual SDIO function driver. To make things simple and manageable, host drivers must advertise their PM capabilities with a feature bitmask, then function drivers can query and set those features from their suspend method. Then each layer in the suspend call chain is expected to act upon those bits accordingly.

2010-03-06sdhci: improve sdhci sdhci_set_adma_desc() codeBen Dooks
sdhci_set_adma_desc() is using byte-writes to write data in a specified order into memory. Change to using __le16 for the two byte and __le32 for the four byte cases and use the cpu_to_{le16,le32} to do the conversion before writing. This will reduce the size of the code and the number of writes as we no longer need to chop the data up before writing. As an example on ARM S3C64XX SoC, in little-endian configuration: 000000d4 <sdhci_set_adma_desc>: - d8: e1a0c423 lsr ip, r3, #8 - dc: e1a0ec21 lsr lr, r1, #24 - e0: e1a04821 lsr r4, r1, #16 - e4: e1a05421 lsr r5, r1, #8 - e8: e1a06442 asr r6, r2, #8 - ec: e5c0c001 strb ip, [r0, #1] - f0: e5c0e007 strb lr, [r0, #7] - f4: e5c04006 strb r4, [r0, #6] - f8: e5c05005 strb r5, [r0, #5] - fc: e5c01004 strb r1, [r0, #4] - 100: e5c06003 strb r6, [r0, #3] - 104: e5c02002 strb r2, [r0, #2] - 108: e5c03000 strb r3, [r0] + d4: e5801004 str r1, [r0, #4] + d8: e1c030b0 strh r3, [r0] + dc: e1c020b2 strh r2, [r0, #2] Signed-off-by: Ben Dooks <ben-linux@fluff.org> Cc: Pierre Ossman <pierre@ossman.eu> Cc: <linux-mmc@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2010-03-06ricoh_mmc: port from driver to pci quirkMaxim Levitsky
This patch solves nasty problem original driver has. Original goal of the ricoh_mmc was to disable this device because then, mmc cards can be read using standard SDHCI controller, thus avoiding writing of yet another driver. However, the act of disablement, makes other pci functions that belong to this controller (xD and memstick) shift up one level, thus pci core has now wrong idea about these devices. To fix this issue, this patch moves the driver into the pci quirk section, thus it is executes before the pci is enumerated, and therefore solving that issue, also same sequence of commands is performed on resume for same reasons. Also regardless of the above, this way is cleaner.

2010-03-06drivers/misc/iwmc3200top/main.c: eliminate useless codeJulia Lawall
The variable priv is initialized twice to the same (side effect-free) expression. Drop one initialization. A simplified version of the semantic match that finds this problem is: (http://coccinelle.lip6.fr/) // <smpl> @forall@ idexpression *x; identifier f!=ERR_PTR; @@ x = f(...) ... when != x ( x = f(...,<+...x...+>,...) | * x = f(...) ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2010-03-06MFGPT: move clocksource menuRandy Dunlap
Move the CS5535 MFGPT hrtimer kconfig option to be with the other MFGPT options. This makes it easier to find and also removes it from the main "Device Drivers" menu, where it should not have been.

Reorder struct menu_device to remove 8 bytes of padding on 64 bit builds. Size drops from 136 to 128 bytes, so possibly needing one fewer cache lines.

2010-03-06memory-hotplug: create /sys/firmware/memmap entry for new memoryakpm@linux-foundation.org
A memmap is a directory in sysfs which includes 3 text files: start, end and type. For example: start: 0x100000 end: 0x7e7b1cff type: System RAM Interface firmware_map_add was not called explicitly. Remove it and add function firmware_map_add_hotplug as hotplug interface of memmap. Each memory entry has a memmap in sysfs, When we hot-add new memory, sysfs does not export memmap entry for it. We add a call in function add_memory to function firmware_map_add_hotplug. Add a new function add_sysfs_fw_map_entry() to create memmap entry, it will be called when initialize memmap and hot-add memory.

2010-03-06bitops: rename for_each_bit() to for_each_set_bit()Akinobu Mita
Rename for_each_bit to for_each_set_bit in the kernel source tree. To permit for_each_clear_bit(), should that ever be added. The patch includes a macro to map the old for_each_bit() onto the new for_each_set_bit(). This is a (very) temporary thing to ease the migration.

2010-03-05dquot: cleanup dquot transfer routineChristoph Hellwig
Get rid of the transfer dquot operation - it is now always called from the filesystem and if a filesystem really needs it's own (which none currently does) it can just call into it's own routine directly. Rename the now static low-level dquot_transfer helper to __dquot_transfer and vfs_dq_transfer to dquot_transfer to have a consistent namespace, and make the new dquot_transfer return a normal negative errno value which all callers expect.
