Pull MTD changes from David Woodhouse: - Artem's cleanup of the MTD API continues apace. - Fixes and improvements for ST FSMC and SuperH FLCTL NAND, amongst others. - More work on DiskOnChip G3, new driver for DiskOnChip G4. - Clean up debug/warning printks in JFFS2 to use pr_<level>. Fix up various trivial conflicts, largely due to changes in calling conventions for things like dmaengine_prep_slave_sg() (new inline wrapper to hide new parameter, clashing with rewrite of previously last parameter that used to be an 'append' flag, and is now a bitmap of 'unsigned long flags'). (Also some header file fallout - like so many merges this merge window - and silly conflicts with sparse fixes) * tag 'for-linus-3.4' of git://git.infradead.org/mtd-2.6: (120 commits) mtd: docg3 add protection against concurrency mtd: docg3 refactor cascade floors structure mtd: docg3 increase write/erase timeout mtd: docg3 fix inbound calculations mtd: nand: gpmi: fix function annotations mtd: phram: fix section mismatch for phram_setup mtd: unify initialization of erase_info->fail_addr mtd: support ONFI multi lun NAND mtd: sm_ftl: fix typo in major number. mtd: add device-tree support to spear_smi mtd: spear_smi: Remove default partition information from driver mtd: Add device-tree support to fsmc_nand mtd: fix section mismatch for doc_probe_device mtd: nand/fsmc: Remove sparse warnings and errors mtd: nand/fsmc: Add DMA support mtd: nand/fsmc: Access the NAND device word by word whenever possible mtd: nand/fsmc: Use dev_err to report error scenario mtd: nand/fsmc: Use devm routines mtd: nand/fsmc: Modify fsmc driver to accept nand timing parameters via platform mtd: fsmc_nand: add pm callbacks to support hibernation ...

2012-03-30ACPI throttling: fix endian bug in acpi_read_throttling_status()Dan Carpenter
Using a u64 here creates an endian bug. We store a u32 number in the top byte which is a larger number than intended on big endian systems. There is no reason to use a 64 bit data type here, I guess it was just an oversight. I removed the initialization to zero as well. It's needed with a u64 but with a u32, the variable gets initialized properly inside the call to acpi_os_read_port().

2012-03-30ACPI: Fix unprotected smp_processor_id() in acpi_processor_cst_has_changed()Paul E. McKenney
The acpi_processor_cst_has_changed() function is invoked from a CPU_ONLINE or CPU_DEAD function, which might well execute on CPU 0 even though the CPU being hotplugged is some other CPU. In addition, acpi_processor_cst_has_changed() invokes smp_processor_id() without protection, resulting in splats when onlining CPUs.

2012-03-30ACPI: processor_driver: add missing kfreeJulia Lawall
The function acpi_processor_add is stored in the ops.add field of a acpi_driver structure. This function is then called in acpi_bus_driver_init. On failure, this function clears the field device->driver_data, but does not free its contents. Thus the free has to be done by the add function. In acpi_processor_add, the corresponding value is pr. This value is currently freed on failure before storing it in device->driver_data, but not after. This free is added in the error handling code at the end of the function. The per_cpu variable processors is also cleared so that it does not refer to a dangling pointer. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Reviewed-by: Srivatsa S.

2012-03-30ACPI, APEI: Fix incorrect APEI register bit width check and usageGary Hade
The current code incorrectly assumes that (1) the APEI register bit width is always 8, 16, 32, or 64 and (2) the APEI register bit width is always equal to the APEI register access width.

2012-03-30ACPI, APEI, EINJ, new parameter to control trigger actionChen Gong
Some APEI firmware implementation will access injected address specified in param1 to trigger the error when injecting memory error, which means if one SRAR error is injected, the crash always happens because it is executed in kernel context. This new parameter can disable trigger action and control is taken over by the user. In this way, an SRAR error can happen in user context instead of crashing the system.

2012-03-30cpuidle: add a sysfs entry to disable specific C state for debug purpose.ShuoX Liu
Some C states of new CPU might be not good. One reason is BIOS might configure them incorrectly. To help developers root cause it quickly, the patch adds a new sysfs entry, so developers could disable specific C state manually. In addition, C state might have much impact on performance tuning, as it takes much time to enter/exit C states, which might delay interrupt processing. With the new debug option, developers could check if a deep C state could impact performance and how much impact it could cause. Also add this option in Documentation/cpuidle/sysfs.txt.

Then Dev0 is resumed first and it goes into D0 state. But Dev1 is left in D0_Uninitialised state. This is wrong. In this case, Dev1 must be resumed too. In order to hand this case, each power resource maintains a list of devices which relies on it. When power resource is ON, it will check if the devices on its list can be resumed.
