Pull more ACPI and power management fixes and updates from Rafael Wysocki:
"This is PM and ACPI material that has emerged over the last two weeks
and one fix for a CPU hotplug regression introduced by the recent CPU
hotplug notifiers registration series.
Included are intel_idle and turbostat updates from Len Brown (these
have been in linux-next for quite some time), a new cpufreq driver for
powernv (that might spend some more time in linux-next, but BenH was
asking me so nicely to push it for 3.15 that I couldn't resist), some
cpufreq fixes and cleanups (including fixes for some silly breakage in
a couple of cpufreq drivers introduced during the 3.14 cycle),
assorted ACPI cleanups, wakeup framework documentation fixes, a new
sysfs attribute for cpuidle and a new command line argument for power
domains diagnostics.
Specifics:

kconfig: make allnoconfig disable options behind EMBEDDED and EXPERT
"make allnoconfig" exists to ease testing of minimal configurations. Documentation/SubmitChecklist includes a note to test with allnoconfig. This helps catch missing dependencies on common-but-not-required functionality, which might otherwise go unnoticed. However, allnoconfig still leaves many symbols enabled, because they're hidden behind CONFIG_EMBEDDED or CONFIG_EXPERT. For instance, allnoconfig still has CONFIG_PRINTK and CONFIG_BLOCK enabled, so drivers don't typically get build-tested with those disabled. To address this, introduce a new Kconfig option "allnoconfig_y", used on symbols which only exist to hide other symbols. Set it on CONFIG_EMBEDDED (which then selects CONFIG_EXPERT). allnoconfig will then disable all the symbols hidden behind those.

affs: add mount option to avoid filename truncates
Normal behavior for filenames exceeding specific filesystem limits is to refuse operation. AFFS standard name length being only 30 characters against 255 for usual Linux filesystems, original implementation does filename truncate by default with a define value AFFS_NO_TRUNCATE which can be enabled but needs module compilation. This patch adds 'nofilenametruncate' mount option so that user can easily activate that feature and avoid a lot of problems (eg overwrite files ...)

rapidio: rework device hierarchy and introduce mport class of devices
This patch removes an artificial RapidIO bus root device and establishes actual device hierarchy by providing reference to real parent devices. It also introduces device class for RapidIO controller devices (on-chip or an eternal bridge, known as "mport"). Existing implementation was sufficient for SoC-based platforms that have a single RapidIO controller. With introduction of devices using multiple RapidIO controllers and PCIe-to-RapidIO bridges the old scheme is very limiting or does not work at all. The implemented changes allow to properly reference platform's local RapidIO mport devices and provide device details needed for upper layers. This change to RapidIO device hierarchy does not break any known existing kernel or user space interfaces.

zram: add multi stream functionality
Existing zram (zcomp) implementation has only one compression stream (buffer and algorithm private part), so in order to prevent data corruption only one write (compress operation) can use this compression stream, forcing all concurrent write operations to wait for stream lock to be released. This patch changes zcomp to keep a compression streams list of user-defined size (via sysfs device attr). Each write operation still exclusively holds compression stream, the difference is that we can have N write operations (depending on size of streams list) executing in parallel. See TEST section later in commit message for performance data. Introduce struct zcomp_strm_multi and a set of functions to manage zcomp_strm stream access. zcomp_strm_multi has a list of idle zcomp_strm structs, spinlock to protect idle list and wait queue, making it possible to perform parallel compressions. The following set of functions added: - zcomp_strm_multi_find()/zcomp_strm_multi_release() find and release a compression stream, implement required locking - zcomp_strm_multi_create()/zcomp_strm_multi_destroy() create and destroy zcomp_strm_multi zcomp ->strm_find() and ->strm_release() callbacks are set during initialisation to zcomp_strm_multi_find()/zcomp_strm_multi_release() correspondingly. Each time zcomp issues a zcomp_strm_multi_find() call, the following set of operations performed: - spin lock strm_lock - if idle list is not empty, remove zcomp_strm from idle list, spin unlock and return zcomp stream pointer to caller - if idle list is empty, current adds itself to wait queue. it will be awaken by zcomp_strm_multi_release() caller. zcomp_strm_multi_release(): - spin lock strm_lock - add zcomp stream to idle list - spin unlock, wake up sleeper Minchan Kim reported that spinlock-based locking scheme has demonstrated a severe perfomance regression for single compression stream case, comparing to mutex-based (see https://lkml.org/lkml/2014/2/18/16) base spinlock mutex ==Initial write ==Initial write ==Initial write records: 5 records: 5 records: 5 avg: 1642424.35 avg: 699610.40 avg: 1655583.71 std: 39890.95(2.43%) std: 232014.19(33.16%) std: 52293.96 max: 1690170.94 max: 1163473.45 max: 1697164.75 min: 1568669.52 min: 573429.88 min: 1553410.23 ==Rewrite ==Rewrite ==Rewrite records: 5 records: 5 records: 5 avg: 1611775.39 avg: 501406.64 avg: 1684419.11 std: 17144.58(1.06%) std: 15354.41(3.06%) std: 18367.42 max: 1641800.95 max: 531356.78 max: 1706445.84 min: 1593515.27 min: 488817.78 min: 1655335.73 When only one compression stream available, mutex with spin on owner tends to perform much better than frequent wait_event()/wake_up(). This is why single stream implemented as a special case with mutex locking. Introduce and document zram device attribute max_comp_streams. This attr shows and stores current zcomp's max number of zcomp streams (max_strm). Extend zcomp's zcomp_create() with `max_strm' parameter. `max_strm' limits the number of zcomp_strm structs in compression backend's idle list (max_comp_streams). max_comp_streams used during initialisation as follows: -- passing to zcomp_create() max_strm equals to 1 will initialise zcomp using single compression stream zcomp_strm_single (mutex-based locking). -- passing to zcomp_create() max_strm greater than 1 will initialise zcomp using multi compression stream zcomp_strm_multi (spinlock-based locking). default max_comp_streams value is 1, meaning that zram with single stream will be initialised. Later patch will introduce configuration knob to change max_comp_streams on already initialised and used zcomp.

mm: introduce vm_ops->map_pages()
Here's new version of faultaround patchset. It took a while to tune it and collect performance data. First patch adds new callback ->map_pages to vm_operations_struct. ->map_pages() is called when VM asks to map easy accessible pages. Filesystem should find and map pages associated with offsets from "pgoff" till "max_pgoff". ->map_pages() is called with page table locked and must not block. If it's not possible to reach a page without blocking, filesystem should skip it. Filesystem should use do_set_pte() to setup page table entry. Pointer to entry associated with offset "pgoff" is passed in "pte" field in vm_fault structure. Pointers to entries for other offsets should be calculated relative to "pte". Currently VM use ->map_pages only on read page fault path. We try to map FAULT_AROUND_PAGES a time. FAULT_AROUND_PAGES is 16 for now. Performance data for different FAULT_AROUND_ORDER is below. TODO: - implement ->map_pages() for shmem/tmpfs; - modify get_user_pages() to be able to use ->map_pages() and implement mmap(MAP_POPULATE|MAP_NONBLOCK) on top. ========================================================================= Tested on 4-socket machine (120 threads) with 128GiB of RAM.

On read page fault, if filesystem provides ->map_pages(), we try to map up to FAULT_AROUND_PAGES pages around page fault address in hope to reduce number of minor page faults. We call ->map_pages first and use ->fault() as fallback if page by the offset is not ready to be mapped (cold page cache or something). Signed-off-by: Kirill A.

CPU hotplug notifiers registration fixes for 3.15-rc1
The purpose of this single series of commits from Srivatsa S Bhat (with a small piece from Gautham R Shenoy) touching multiple subsystems that use CPU hotplug notifiers is to provide a way to register them that will not lead to deadlocks with CPU online/offline operations as described in the changelog of commit |

sched: remove sleep_on() and friends
This is the final piece in the puzzle, as all patches to remove the last users of \(interruptible_\|\)sleep_on\(_timeout\|\) have made it into the 3.15 merge window. The work was long overdue, and this interface in particular should not have survived the BKL removal that was done a couple of years ago. Citing Jon Corbet from http://lwn.net/2001/0201/kernel.php3": "[...] it was suggested that the janitors look for and fix all code that calls sleep_on() [...] since (1) almost all such code is incorrect, and (2) Linus has agreed that those functions should be removed in the 2.5 development series". We haven't quite made it for 2.5, but maybe we can merge this for 3.15.

PM / wakeup: Correct presence vs. emptiness of wakeup_* attributes
According to the documentation, the various wakeup_* attributes in sysfs are not present if the device is not enabled to wake up the system. This is not correct: the attributes are not present if the device is not capable to wake up the system. They are empty if the device is not enabled to wake up the system.

f2fs: introduce f2fs_issue_flush to avoid redundant flush issue
Some storage devices show relatively high latencies to complete cache_flush commands, even though their normal IO speed is prettry much high. In such the case, it needs to merge cache_flush commands as much as possible to avoid issuing them redundantly. So, this patch introduces a mount option, "-o flush_merge", to mitigate such the overhead. If this option is enabled by user, F2FS merges the cache_flush commands and then issues just one cache_flush on behalf of them. Once the single command is finished, F2FS sends a completion signal to all the pending threads. Note that, this option can be used under a workload consisting of very intensive concurrent fsync calls, while the storage handles cache_flush commands slowly.

Fix corruption due to non-atomic transaction commit which allowed a metadata superblock to be written before all other metadata was successfully written -- this is common to all targets that use the persistent-data library's transaction manager (dm-thinp, dm-cache and dm-era). . Various small cleanups in the DM core . Add the dm-era target which is useful for keeping track of which blocks were written within a user defined period of time called an 'era'.

Improve the on-disk layout of multithreaded writes to the dm-thin-pool by splitting the pool's deferred bio list to be a per-thin device list and then sorting that list using an rb_tree. The subsequent read throughput of the data written via multiple threads improved by ~70%. .

* Device-tree support for OMAP IOMMU
* Convert OMAP IOMMU to use devm_* interfaces
* Fixed PASID support for AMD IOMMU
* Other random cleanups and fixes for OMAP, ARM-SMMU

Most of the changes are in the VT-d driver because some rework was
necessary for better hotplug and ACPI device support.

ARM: SoC: late cleanups
These could not be part of the first cleanup branch, because they either
came too late in the cycle, or they have dependencies on other branches.
Important changes are:
* The integrator platform is almost multiplatform capable after
some reorganization (Linus Walleij)
* Minor cleanups on Zynq (Michal Simek)
* Lots of changes for Exynos and other Samsung platforms, including
further preparations for multiplatform support and the clocks bindings
are rearranged.

ARM: SoC: driver changes
These changes are mostly for ARM specific device drivers that either don't have an upstream maintainer, or that had the maintainer ask us to pick up the changes to avoid conflicts. A large chunk of this are clock drivers (bcm281xx, exynos, versatile, shmobile), aside from that, reset controllers for STi as well as a large rework of the Marvell Orion/EBU watchdog driver are notable. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUz/1+GCrR//JCVInAQJmfg/9GyqHatDjjUPUBjUQRIEtKgGdmQwdbDqF x+OrS/q5B5zYbpIWkbkt1IUYJfU+89Z5ev9jxI4rV824Nu9Y92mHPDnv+N/ptkIh q2OVP3bQDpWs3aEVV2B1HBNcWrNUuwco9BJu05eegEePii/cto0/wKwWIgUmrmjy xOLthsnp2YmeplGs7ctC6Dz8XbmELebpawejTGylARXei/SwmzB/YYDgJbYjRL2I WSCVa8Vo+MZaGC/yxdKVTtvsKVQenxGoMO3ojikJeRdvuVRJds48Cw+UBdzWYNeJ 3Ssvbdx6Xltf9jy/7H0btOUgxPetZuUV+2XpbWfGu0Zr9FcGDv3q9hrxA+UYKnkY GIGU0otSsmpHnX5Ms3E2xnHiV/fihxA3qohqts5kYRBDr5uc+IpW6SbDymQliCGG OO4XmIVM3pmsqAqP3Zuseemt9CeSW2yC0XlfXkzjO74yY39c+WLBbtGI40Z5W6i0 mM1C8RD3QSNijYCEC8eqz06BQfRImsPs+jllsnJTZaHfbOsib718uvandjfG26lN 616YMcqq0Sp51HIQ4qW7f2dQr7vOyNqbukdkrwF5JgkY/nVki5kdciRg/yeipRy6 Ey80a+OTq0GQljM0F2dcH/A1eHH9KsuI1L6NdSMJsl0h6guIBORPTwTw3qJ13OkR wpJyM+Gm+Fk= =u/FI -----END PGP SIGNATURE----- Merge tag 'drivers-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver changes from Arnd Bergmann: "These changes are mostly for ARM specific device drivers that either don't have an upstream maintainer, or that had the maintainer ask us to pick up the changes to avoid conflicts.

ARM: SoC: device tree changes
A large part of the arm-soc patches are nowadays DT changes, adding support for new SoCs, boards and devices without changing kernel source. The plan is still to move the devicetree files out of the kernel tree and reduce the amount of churn going on here, but we keep finding reasons to delay doing that. Changes are really all over the place, with little sticking out particularly. We have contributions from a total of 116 people in this branch. Unfortunately, the size of this branch also causes a significant number of conflicts at the moment, typically when subsystem maintainers merge patches that change the driver at the same time as the dts files. In most cases this could be avoided because the dts changes are supposed to be compatible in both ways, and we are asking everyone to send ARM dts changes through our tree only. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUz/11WCrR//JCVInAQIIyRAA0DjdNNQ/A4G2i1nZCiTFH6a4oZy4JarN ATVPkW/V8avhh+yVNe5FWA44Xe6CDC5TXwMaIsbK+w3Iclj3fplh/MsBkQ9ZT9Sl LAjJoOjuYucCeDy0WLVioRKZ4PJEDoCu/oZTauIMnmWCOCRxLYpOM3FkAT9oN/Ti lswpTSLiV1/U3ZSI4M3qn+Sx1VJL8c/hAIWbvf5if2diYkWPk3VOSKyxmD9zLWdD Iqtb79J+ETVeOIM4sHnx79cG4ZCdpOfRAl7qx6hkJu0YATXESxWhpXVE2McTJuzM qHKsRRNSfsfSWPeF4angll9o06X/qgdT6C4P2dfH49lGeG7llOttw3OaCx3hWCTe U5bt26qtbwG2ZbzocaqvideP+rbpQrCH2vdO1embPv5Lu6peMoBWjxy6twSVXJBG LIymJ0IbiGYxL7BReGqRXt6ehy0BDWBeTSTdsGqgEl2TnxHuS/kgGfJc4D5riiEk aRPVq10p/k+yo4BZtq2GqXIOG6cqkIQ5lhl5Tg9+MfUlquAONqJP70FgRJDBIw9L 9uJp71bgSsA6eYg2tXoqJtpdjKplDWavgtACzIkFg2qFLyYmKvx+F0AXbeTIsrri /mIchTyG+dgiIjWvj/Xsf7jhrdzRcl3uKsJwFmk927pIsh24HV8T+LKgHrf+sVcO qEsEnKGYA6s= =zl/N -----END PGP SIGNATURE----- Merge tag 'dt-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device tree changes from Arnd Bergmann: "A large part of the arm-soc patches are nowadays DT changes, adding support for new SoCs, boards and devices without changing kernel source.
