Add ->tmu_initialize method to struct exynos_tmu_data and use it in exynos_tmu_initialize(). Then add ->tmu_initialize implementations for Exynos4210, Exynos4412+ and Exynos5440. Finally remove no longer needed reg->threshold_th[0,1], reg->intclr_[fall,rise]_shift and reg->intclr_[rise,fall]_mask abstractions. There are more improvements available in the future on top of this patch like merging HW_TRIP level setting with setting of other levels for Exynos4412+ or adding separate method for clearing IRQs using INTCLEAR register (for Exynos5420, Exynos5260 and Exynos4412+). There should be no functional changes caused by this patch.

Different drivers request API extensions in of-thermal. For this reason, additional callbacks are required to fit the new drivers needs. The current API implementation expects the registering sensor driver to provide a get_temp and get_trend callbacks as function parameters. As the amount of callbacks is growing, this patch changes the existing implementation to use a .ops field to hold all the of thermal callbacks to sensor drivers. This patch also changes the existing of-thermal users to fit the new API design. No functional change is introduced in this patch.

This patch introduces a new thermal cooling device based on common clock framework. The original motivation to write this cooling device is to be able to cool down thermal zones using clocks that feed co-processors, such as GPUs, DSPs, Image Processing Co-processors, etc. But it is written in a way that it can be used on top of any clock. The implementation is pretty straight forward. The code creates a thermal cooling device based on a pair of a struct device and a clock name. The struct device is assumed to be usable by the OPP layer. The OPP layer is used as source of the list of possible frequencies. The (cpufreq) frequency table is then used as a map from frequencies to cooling states. Cooling states are indexes to the frequency table. The logic sits on top of common clock framework, specifically on clock pre notifications. Any PRE_RATE_CHANGE is hijacked, and the transition is only allowed when the new rate is within the thermal limit (cooling state -> freq). When a thermal cooling device state transition is requested, the clock is also checked to verify if the current clock rate is within the new thermal limit.

md_check_recovery will skip any recovery and also clear MD_RECOVERY_NEEDED if MD_RECOVERY_FROZEN is set. So when we clear _FROZEN, we must set _NEEDED and ensure that md_check_recovery gets run. Otherwise we could miss out on something that is needed. In particular, this can make it impossible to remove a failed device from an array is the 'recovery-needed' processing didn't happen.

Al Viro pointed out that the x86-64 csum_partial_copy_from_user() is somewhat confused about what it should do on errors, notably it mostly clears the uncopied end result buffer, but misses that for the initial alignment case. All users should check for errors, so it's dubious whether the clearing is even necessary, and Al also points out that we should probably clean up the calling conventions, but regardless of any future changes to this function, the fact that it is inconsistent is just annoying. So make the __get_user() failure path use the same error exit as all the other errors do.

Pull ARM fixes from Russell King: "Two fixes this time, one to ensure that the kuser helper option depends on MMU as they aren't available for noMMU targets (and if the option is selected, we end up oopsing.) The second fix plugs a corner case with the decompressor, ensuring that the instruction stream can see the relocated code in every case on ARMv7 CPUs" * 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: ARM: 8198/1: make kuser helpers depend on MMU ARM: 8191/1: decompressor: ensure I-side picks up relocated code
