Pull regulator updates from Mark Brown: "Another release, another set of regulator updates. Not much of it is showing up in the code yet but there's been a lot of discussion going on about how to enhance the regulator API to work better with modern SoCs which have a microcontroller sitting between Linux and the hardware. I'm hopeful that'll start to come through into mainline for v4.2 but it's not quite there for v4.1 - what we do have (along with the usual small updates is) is: - work from Bjorn Andersson on refactoring the configuration of regulator loading interfaces to be useful for use with microcontrollers, the existing interfaces were never actually useful for anything as-is since nobody was willing to put enough data into public code. - a summary tree display in debugfs from Heiko Stübner. - support for act6000 regulators" * tag 'regulator-v4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (34 commits) regulator: max8660: Handle empty regulator data regulator: output current-limit for all regulators in summary regulator: add a summary tree in debugfs regulator: qcom: Tidy up probe() regulator: qcom: Rework to single platform device regulator: qcom: Refactor of-parsing code regulator: qcom: Don't enable DRMS in driver regulator: max8660: fix assignment of pdata to data that becomes dead regulator: Defer lookup of supply to regulator_get mfd: max77693: Remove unused structures regulator: max77693: Let core parse DT and drop board files support regulator: Ensure unique regulator debugfs directory names regulator: stw481x: Remove unused fields from struct stw481x regulator: palmas: Add has_regen3 check for TPS659038 regulator: constify of_device_id array regulator: fixes for regulator_set_optimum_mode name change regulator: Drop temporary regulator_set_optimum_mode wrapper usb: phy: phy-msm-usb: Rename regulator_set_optimum_mode usb: phy: ab8500-usb: Rename regulator_set_optimum_mode ufs: Rename of regulator_set_optimum_mode ...

Almost all arches define ELF_ET_DYN_BASE as 2/3 of TASK_SIZE. Though it seems that some architectures do this in a wrong way. The problem is that 2*TASK_SIZE may overflow 32-bits so the real ELF_ET_DYN_BASE becomes wrong. Fix this overflow by dividing TASK_SIZE prior to multiplying: (TASK_SIZE / 3 * 2) Signed-off-by:

Pull last-minute ASoC fix from Mark Brown: "This patch backs out a change that came in during the merge window which selects a configuration for GPIO4 on pcm512x CODECs that may not be suitable for all systems using the device. Changes for v4.1 will make this properly configurable but for now it's safest to revert to the v3.19 behaviour and leave the pin configuration alone. Sorry for sending this direct at the last minute but due to the GPIO misuse it'd be really good to get it in the release and I'd not realised it hadn't been sent yet - between some travel, a job change and other non-urgent fixes coming in I'd lost track of the urgency. It's been in -next for several weeks now, is isolated to the driver and fairly clear to inspection" * tag 'asoc-fix-v4.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound: ASoC: pcm512x: Remove hardcoding of pll-lock to GPIO4
