2014-10-27ARM: OMAP2/3: CM: make cm_split_idlest_reg SoC calls staticTero Kristo
CM driver has a generic API which calls the SoC specific split function through cm_ll_data, so there is no need for the SoC specific functions to be publicly available.

2014-10-27ARM: OMAP2+: CM: add common API for cm_wait_module_readyTero Kristo
This patch consolidates the parameters provided for the SoC specific cm_*_wait_module_ready calls, adds the missing cm_ll_data function pointers and uses the now generic call from the mach-omap2 board code. SoC specific *_wait_module_ready calls are also made static so they can only be accessed through the generic CM driver API only.

2014-10-27s390/vdso: fix stack corruptionHeiko Carstens
The kernel provided vdso functions do not get a stack frame from the calling function and therefore may not change the stack contents, unless they allocate space on their own. This problem was exposed with 070b7be633dc "s390/vdso: replace stck with stcke" which writes 16 bytes instead of 8 bytes into the stack frame. These additional 8 bytes however were indeed used by the caller (glibc) to save data and therefore this data was corrupted by the vdso code.

2014-10-27mm: cma: Ensure that reservations never cross the low/high mem boundaryLaurent Pinchart
Commit 95b0e655f914 ("ARM: mm: don't limit default CMA region only to low memory") extended CMA memory reservation to allow usage of high memory. It relied on commit f7426b983a6a ("mm: cma: adjust address limit to avoid hitting low/high memory boundary") to ensure that the reserved block never crossed the low/high memory boundary. While the implementation correctly lowered the limit, it failed to consider the case where the base..limit range crossed the low/high memory boundary with enough space on each side to reserve the requested size on either low or high memory. Rework the base and limit adjustment to fix the problem. The function now starts by rejecting the reservation altogether for fixed reservations that cross the boundary, tries to reserve from high memory first and then falls back to low memory.

2014-10-27mm: cma: Always consider a 0 base address reservation as dynamicLaurent Pinchart
The fixed parameter to cma_declare_contiguous() tells the function whether the given base address must be honoured or should be considered as a hint only. The API considers a zero base address as meaning any base address, which must never be considered as a fixed value. Part of the implementation correctly checks both fixed and base != 0, but two locations check the fixed value only. Set fixed to false when base is 0 to fix that and simplify the code.

2014-10-27mm: cma: Don't crash on allocation if CMA area can't be activatedLaurent Pinchart
If activation of the CMA area fails its mutex won't be initialized, leading to an oops at allocation time when trying to lock the mutex. Fix this by setting the cma area count field to 0 when activation fails, leading to allocation returning NULL immediately.

2014-10-27drm/i915: Ignore long hpds on eDP portsVille Syrjälä
Turning vdd on/off can generate a long hpd pulse on eDP ports. In order to handle hpd we would need to turn on vdd to perform aux transfers. This would lead to an endless cycle of "vdd off -> long hpd -> vdd on -> detect -> vdd off -> ..." So ignore long hpd pulses on eDP ports. eDP panels should be physically tied to the machine anyway so they should not actually disappear and thus don't need long hpd handling. Short hpds are still needed for link re-train and whatnot so we can't just turn off the hpd interrupt entirely for eDP ports. Perhaps we could turn it off whenever the panel is disabled, but just ignoring the long hpd seems sufficient.

2014-10-27drm/i915: Do a dummy DPCD read before the actual readVille Syrjälä
Sometimes we seem to get utter garbage from DPCD reads. The resulting buffer is filled with the same byte, and the operation completed without errors. My HP ZR24w monitor seems particularly susceptible to this problem once it's gone into a sleep mode. The issue seems to happen only for the first AUX message that wakes the sink up. But as the first AUX read we often do is the DPCD receiver cap it does wreak a bit of havoc with subsequent link training etc. when the receiver cap bw/lane/etc. information is garbage. A sufficient workaround seems to be to perform a single byte dummy read before reading the actual data. I suppose that just wakes up the sink sufficiently and we can just throw away the returned data in case it's crap. DP_DPCD_REV seems like a sufficiently safe location to read here.
