Pull compat time conversion changes from Peter Anvin: "Despite the branch name this is really neither an x86 nor an x32-specific patchset, although it the implementation of the discussions that followed the x32 security hole a few months ago. This removes get/put_compat_timespec/val() and replaces them with compat_get/put_timespec/val() which are savvy as to the current status of COMPAT_USE_64BIT_TIME. It removes several unused and/or incorrect/misleading functions (like compat_put_timeval_convert which doesn't in fact do any conversion) and also replaces several open-coded implementations what is now called compat_convert_timespec() with that function" * 'x86-x32-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: compat: Fix sparse address space warnings compat: Get rid of (get|put)_compat_time(val|spec)

Pull x86 vdso changes from Peter Anvin: "This is the revamp of the 32-bit vdso and the associated cleanups. This adds timekeeping support to the 32-bit vdso that we already have in the 64-bit vdso. Although 32-bit x86 is legacy, it is likely to remain in the embedded space for a very long time to come. This removes the traditional COMPAT_VDSO support; the configuration variable is reused for simply removing the 32-bit vdso, which will produce correct results but obviously suffer a performance penalty. Only one beta version of glibc was affected, but that version was unfortunately included in one OpenSUSE release. This is not the end of the vdso cleanups. Stefani and Andy have agreed to continue work for the next kernel cycle; in fact Andy has already produced another set of cleanups that came too late for this cycle. An incidental, but arguably important, change is that this ensures that unused space in the VVAR page is properly zeroed. It wasn't before, and would contain whatever garbage was left in memory by BIOS or the bootloader. Since the VVAR page is accessible to user space this had the potential of information leaks" * 'x86-vdso-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (23 commits) x86, vdso: Fix the symbol versions on the 32-bit vDSO x86, vdso, build: Don't rebuild 32-bit vdsos on every make x86, vdso: Actually discard the .discard sections x86, vdso: Fix size of get_unmapped_area() x86, vdso: Finish removing VDSO32_PRELINK x86, vdso: Move more vdso definitions into vdso.h x86: Load the 32-bit vdso in place, just like the 64-bit vdsos x86, vdso32: handle 32 bit vDSO larger one page x86, vdso32: Disable stack protector, adjust optimizations x86, vdso: Zero-pad the VVAR page x86, vdso: Add 32 bit VDSO time support for 64 bit kernel x86, vdso: Add 32 bit VDSO time support for 32 bit kernel x86, vdso: Patch alternatives in the 32-bit VDSO x86, vdso: Introduce VVAR marco for vdso32 x86, vdso: Cleanup __vdso_gettimeofday() x86, vdso: Replace VVAR(vsyscall_gtod_data) by gtod macro x86, vdso: __vdso_clock_gettime() cleanup x86, vdso: Revamp vclock_gettime.c mm: Add new func _install_special_mapping() to mmap.c x86, vdso: Make vsyscall_gtod_data handling x86 generic ...

Pull x86 boot changes from Peter Anvin: "This patchset is a set of cleanups aiming at librarize some of the common code from the boot environments. We currently have three different "little environments" (boot, boot/compressed, and realmode/rm) in x86, and we are likely to soon get a fourth one (kexec/purgatory, which will have to be integrated in the kernel to support secure kexec). This is primarily a cleanup in the anticipation of the latter. While Vivek implemented this, he ran into some bugs, in particular the memcmp implementation for when gcc punts from using the builtin would have a misnamed symbol, causing compilation errors if we were ever unlucky enough that gcc didn't want to inline the test" * 'x86/boot' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, boot: Move memset() definition in compressed/string.c x86, boot: Move memcmp() into string.h and string.c x86, boot: Move optimized memcpy() 32/64 bit versions to compressed/string.c x86, boot: Create a separate string.h file to provide standard string functions x86, boot: Undef memcmp before providing a new definition

Commit 2223f6f6 "x86: Clean up dumpstack_64.c code" changed the irq_stack processing a little from what it was before. The irq_stack_end variable needed to be cleared after its first use. By setting irq_stack to the per cpu irq_stack and passing that to analyze_stack(), and then clearing it after it is processed, we can get back the original behavior. Signed-off-by:

Commit 2223f6f6 "x86: Clean up dumpstack_64.c code" moved the used variable to a local within the loop, but the in_exception_stack() depended on being non-volatile with the ability to change it. By always re-initializing the "used" variable to zero, it would cause the in_exception_stack() to return the same thing each time, and cause the dump_stack loop to go into an infinite loop.

Pull sound updates from Takashi Iwai: "There have been lots of changes in ALSA core, HD-audio and ASoC, also most of PCI drivers touched by conversions of printks. All these resulted in a high volume and wide ranged patch sets in this release. Many changes are fairly trivial, but also lots of nice cleanups and refactors. There are a few new drivers, most notably, the Intel Haswell and Baytrail ASoC driver. Core changes: - A bit modernization; embed the device struct into snd_card struct, so that it may be referred from the beginning. A new snd_card_new() function is introduced for that, and all drivers have been converted. - Simplification in the device management code in ALSA core; now managed by a simple priority list instead - Converted many kernel messages to use the standard dev_err() & co; this would be the pretty visible difference, especially for HD-audio. HD-audio: - Conexant codecs use the auto-parser as default now; the old static code still remains in case of regressions. Some old quirks have been rewritten with the fixups for auto-parser. - C-Media codecs also use the auto-parser as default now, too. - A device struct is assigned to each HD-audio codec, and the formerly hwdep attributes are accessible over the codec sysfs, too. hwdep attributes still remain for compatibility. - Split the PCI-specific stuff for HD-audio controller into a separate module, ane make a helper module for the generic controller driver. This is a preliminary change for supporting Tegra HDMI controller in near future, which slipped from 3.15 merge. - Device-specific fixes: mute LED support for Lenovo Ideapad, mic LED fix for HP laptops, more ASUS subwoofer quirks, yet more Dell laptop headset quirks - Make the HD-audio codec response a bit more robust - A few improvements on Realtek ALC282 / 283 about the pop noises - A couple of Intel HDMI fixes ASoC: - Lots of cleanups for enumerations; refactored lots of error prone original codes to use more modern APIs - Elimination of the ASoC level wrappers for I2C and SPI moving us closer to converting to regmap completely and avoiding some randconfig hassle - Provide both manually and transparently locked DAPM APIs rather than a mix of the two fixing some concurrency issues - Start converting CODEC drivers to use separate bus interface drivers rather than having them all in one file helping avoid dependency issues - DPCM support for Intel Haswell and Bay Trail platforms, lots of fixes - Lots of work on improvements for simple-card, DaVinci and the Renesas rcar drivers. - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8 - Fixes for the simple-card DAI format DT mess - DT support for a couple more devices. - Use of the tdm_slot mapping in a few drivers Others: - Support of reset_resume callback for improved S4 in USB-audio driver; the device with boot quirks have been little tested, which we need to watch out in this development cycle - Add PM support for ICE1712 driver (finally!); it's still pretty partial support, only for M-Audio devices" * tag 'sound-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (610 commits) ALSA: ice1712: Add suspend support for M-Audio ICE1712-based cards ALSA: ice1712: add suspend support for ICE1712 chip ALSA: hda - Enable beep for ASUS 1015E ALSA: asihpi: fix some indenting in snd_card_asihpi_pcm_new() ALSA: hda - add headset mic detect quirks for three Dell laptops ASoC: tegra: move AC97 clock handling to the machine driver ASoC: simple-card: Handle many DAI links ASoC: simple-card: Add DT documentation for multi-DAI links ASoC: simple-card: dynamically allocate the DAI link and properties ASoC: imx-ssi: Add .xlate_tdm_slot_mask() support.

Pull ACPI and power management updates from Rafael Wysocki: "The majority of this material spent some time in linux-next, some of it even several weeks. There are a few relatively fresh commits in it, but they are mostly fixes and simple cleanups. ACPI took the lead this time, both in terms of the number of commits and the number of modified lines of code, cpufreq follows and there are a few changes in the PM core and in cpuidle too. A new feature that already got some LWN.net's attention is the device PM QoS extension allowing latency tolerance requirements to be propagated from leaf devices to their ancestors with hardware interfaces for specifying latency tolerance. That should help systems with hardware-driven power management to avoid going too far with it in cases when there are latency tolerance constraints. There also are some significant changes in the ACPI core related to the way in which hotplug notifications are handled. They affect PCI hotplug (ACPIPHP) and the ACPI dock station code too. The bottom line is that all those notification now go through the root notify handler and are propagated to the interested subsystems by means of callbacks instead of having to install a notify handler for each device object that we can potentially get hotplug notifications for. In addition to that ACPICA will now advertise "Windows 2013" compatibility for _OSI, because some systems out there don't work correctly if that is not done (some of them don't even boot). On the system suspend side of things, all of the device suspend and resume callbacks, except for ->prepare() and ->complete(), are now going to be executed asynchronously as that turns out to speed up system suspend and resume on some platforms quite significantly and we have a few more optimizations in that area. Apart from that, there are some new device IDs and fixes and cleanups all over. In particular, the system suspend and resume handling by cpufreq should be improved and the cpuidle menu governor should be a bit more robust now. Specifics: - Device PM QoS support for latency tolerance constraints on systems with hardware interfaces allowing such constraints to be specified. That is necessary to prevent hardware-driven power management from becoming overly aggressive on some systems and to prevent power management features leading to excessive latencies from being used in some cases. - Consolidation of the handling of ACPI hotplug notifications for device objects. This causes all device hotplug notifications to go through the root notify handler (that was executed for all of them anyway before) that propagates them to individual subsystems, if necessary, by executing callbacks provided by those subsystems (those callbacks are associated with struct acpi_device objects during device enumeration). As a result, the code in question becomes both smaller in size and more straightforward and all of those changes should not affect users. - ACPICA update, including fixes related to the handling of _PRT in cases when it is broken and the addition of "Windows 2013" to the list of supported "features" for _OSI (which is necessary to support systems that work incorrectly or don't even boot without it). Changes from Bob Moore and Lv Zheng. - Consolidation of ACPI _OST handling from Jiang Liu. - ACPI battery and AC fixes allowing unusual system configurations to be handled by that code from Alexander Mezin. - New device IDs for the ACPI LPSS driver from Chiau Ee Chew. - ACPI fan and thermal optimizations related to system suspend and resume from Aaron Lu. - Cleanups related to ACPI video from Jean Delvare. - Assorted ACPI fixes and cleanups from Al Stone, Hanjun Guo, Lan Tianyu, Paul Bolle, Tomasz Nowicki. - Intel RAPL (Running Average Power Limits) driver cleanups from Jacob Pan. - intel_pstate fixes and cleanups from Dirk Brandewie. - cpufreq fixes related to system suspend/resume handling from Viresh Kumar. - cpufreq core fixes and cleanups from Viresh Kumar, Stratos Karafotis, Saravana Kannan, Rashika Kheria, Joe Perches. - cpufreq drivers updates from Viresh Kumar, Zhuoyu Zhang, Rob Herring. - cpuidle fixes related to the menu governor from Tuukka Tikkanen. - cpuidle fix related to coupled CPUs handling from Paul Burton. - Asynchronous execution of all device suspend and resume callbacks, except for ->prepare and ->complete, during system suspend and resume from Chuansheng Liu. - Delayed resuming of runtime-suspended devices during system suspend for the PCI bus type and ACPI PM domain. - New set of PM helper routines to allow device runtime PM callbacks to be used during system suspend and resume more easily from Ulf Hansson. - Assorted fixes and cleanups in the PM core from Geert Uytterhoeven, Prabhakar Lad, Philipp Zabel, Rashika Kheria, Sebastian Capella. - devfreq fix from Saravana Kannan" * tag 'pm+acpi-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (162 commits) PM / devfreq: Rewrite devfreq_update_status() to fix multiple bugs PM / sleep: Correct whitespace errors in <linux/pm.h> intel_pstate: Set core to min P state during core offline cpufreq: Add stop CPU callback to cpufreq_driver interface cpufreq: Remove unnecessary braces cpufreq: Fix checkpatch errors and warnings cpufreq: powerpc: add cpufreq transition latency for FSL e500mc SoCs MAINTAINERS: Reorder maintainer addresses for PM and ACPI PM / Runtime: Update runtime_idle() documentation for return value meaning video / output: Drop display output class support fujitsu-laptop: Drop unneeded include acer-wmi: Stop selecting VIDEO_OUTPUT_CONTROL ACPI / gpu / drm: Stop selecting VIDEO_OUTPUT_CONTROL ACPI / video: fix ACPI_VIDEO dependencies cpufreq: remove unused notifier: CPUFREQ_{SUSPENDCHANGE|RESUMECHANGE} cpufreq: Do not allow ->setpolicy drivers to provide ->target cpufreq: arm_big_little: set 'physical_cluster' for each CPU cpufreq: arm_big_little: make vexpress driver depend on bL core driver ACPI / button: Add ACPI Button event via netlink routine ACPI: Remove duplicate definitions of PREFIX ...

Both are needed to replace the homebrewn thread handling in the mmc/sdhci code. - New irq chip callbacks to allow proper support for GPIO based irqs. The GPIO based interrupts need to request/release GPIO resources from request/free_irq. - A few new ARM interrupt chips.
