The fix adds special handling for that case.\n\n - One of recent commits changed the export of acpi_bus_get_device() to\n   EXPORT_SYMBOL_GPL(), which was technically correct but broke existing\n   binary modules using that function including one in particularly\n   widespread use.  Change it back to EXPORT_SYMBOL().\n\n - The intel_pstate driver sometimes fails to disable turbo if its\n   no_turbo sysfs attribute is set.

The interrupted call stack can be randomly deep already and\nthe softirq can dig through it even further.

      "message": "watchdog: update watchdog_thresh properly\n\nwatchdog_tresh controls how often nmi perf event counter checks per-cpu\nhrtimer_interrupts counter and blows up if the counter hasn\u0027t changed\nsince the last check.  The counter is updated by per-cpu\nwatchdog_hrtimer hrtimer which is scheduled with 2/5 watchdog_thresh\nperiod which guarantees that hrtimer is scheduled 2 times per the main\nperiod.  Both hrtimer and perf event are started together when the\nwatchdog is enabled.\n\nSo far so good.  But...\n\nBut what happens when watchdog_thresh is updated from sysctl handler?\n\nproc_dowatchdog will set a new sampling period and hrtimer callback\n(watchdog_timer_fn) will use the new value in the next round.  The\nproblem, however, is that nobody tells the perf event that the sampling\nperiod has changed so it is ticking with the period configured when it\nhas been set up.\n\nThis might result in an ear ripping dissonance between perf and hrtimer\nparts if the watchdog_thresh is increased.  And even worse it might lead\nto KABOOM if the watchdog is configured to panic on such a spurious\nlockup.\n\nThis patch fixes the issue by updating both nmi perf even counter and\nhrtimers if the threshold value has changed.\n\nThe nmi one is disabled and then reinitialized from scratch.  This has\nan unpleasant side effect that the allocation of the new event might\nfail theoretically so the hard lockup detector would be disabled for\nsuch cpus.  On the other hand such a memory allocation failure is very\nunlikely because the original event is deallocated right before.\n\nIt would be much nicer if we just changed perf event period but there\ndoesn\u0027t seem to be any API to do that right now.  It is also unfortunate\nthat perf_event_alloc uses GFP_KERNEL allocation unconditionally so we\ncannot use on_each_cpu() and do the same thing from the per-cpu context.\nThe update from the current CPU should be safe because\nperf_event_disable removes the event atomically before it clears the\nper-cpu watchdog_ev so it cannot change anything under running handler\nfeet.\n\nThe hrtimer is simply restarted (thanks to Don Zickus who has pointed\nthis out) if it is queued because we cannot rely it will fire\u0026adopt to\nthe new sampling period before a new nmi event triggers (when the\ntreshold is decreased).\n\n[akpm@linux-foundation.org: the UP version of __smp_call_function_single ended up in the wrong place]\nSigned-off-by: Michal Hocko \u003cmhocko@suse.cz\u003e\nAcked-by: Don Zickus \u003cdzickus@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@kernel.org\u003e\nCc: Fabio Estevam \u003cfestevam@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

RDPMC will be marked as unavailable\n   to old binaries but that\u0027s within the ABI, this is a capability bit.\n\n - Rename bit 1 to -\u003ecap_bit0_is_deprecated and always set it to 1, so new\n   libraries can reliably detect that bit 0 is deprecated and perma-zero\n   without having to check the kernel version.\n\n - Use bits 2, 3, 4 for the newly defined, correct functionality:\n\n\tcap_user_rdpmc\t\t: 1, /* The RDPMC instruction can be used to read counts */\n\tcap_user_time\t\t: 1, /* The time_* fields are used */\n\tcap_user_time_zero\t: 1, /* The time_zero field is used */\n\n - Rename all the bitfield names in perf_event.h to be different from the\n   old names, to make sure it\u0027s not possible to mis-compile it\n   accidentally with old assumptions.\n\nThe \u0027size\u0027 field can then be used in the future to add new fields and it\nwill act as a natural ABI version indicator as well.\n\nAlso adjust tools/perf/ userspace for the new definitions, noticed by\nAdrian Hunter.\n\nReported-by: Vince Weaver \u003cvincent.weaver@maine.edu\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAlso-Fixed-by: Adrian Hunter \u003cadrian.hunter@intel.com\u003e\nLink: http://lkml.kernel.org/n/tip-zr03yxjrpXesOzzupszqglbv@git.kernel.org\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\n"

Although those\n      notifications are really spurious, we should be able to deal with\n      them nevertheless and that shouldn\u0027t introduce too much overhead.\n      Four commits to make that work properly.\n\n   2) Memory hotplug and hibernation mutual exclusion rework\n\n      This was maent to be a cleanup, but it happens to fix a classical\n      ABBA deadlock between system suspend/hibernation and ACPI memory\n      hotplug which is possible if they are started roughly at the same\n      time.  Three commits rework memory hotplug so that it doesn\u0027t\n      acquire pm_mutex and make hibernation use device_hotplug_lock\n      which prevents it from racing with memory hotplug.\n\n   3) ACPI Intel LPSS (Low-Power Subsystem) driver crash fix\n\n      The ACPI LPSS driver crashes during boot on Apple Macbook Air with\n      Haswell that has slightly unusual BIOS configuration in which one\n      of the LPSS device\u0027s _CRS method doesn\u0027t return all of the\n      information expected by the driver.  Fix from Mika Westerberg, for\n      stable.\n\n   4) ACPICA fix related to Store-\u003eArgX operation\n\n      AML interpreter fix for obscure breakage that causes AML to be\n      executed incorrectly on some machines (observed in practice).\n      From Bob Moore.\n\n   5) ACPI core fix for PCI ACPI device objects lookup\n\n      There still are cases in which there is more than one ACPI device\n      object matching a given PCI device and we don\u0027t choose the one\n      that the BIOS expects us to choose, so this makes the lookup take\n      more criteria into account in those cases.\n\n   6) Fix to prevent cpuidle from crashing in some rare cases\n\n      If the result of cpuidle_get_driver() is NULL, which can happen on\n      some systems, cpuidle_driver_ref() will crash trying to use that\n      pointer and the Daniel Fu\u0027s fix prevents that from happening.\n\n   7) cpufreq fixes related to CPU hotplug\n\n      Stephen Boyd reported a number of concurrency problems with\n      cpufreq related to CPU hotplug which are addressed by a series of\n      fixes from Srivatsa S Bhat and Viresh Kumar.\n\n   8) cpufreq fix for time conversion in time_in_state attribute\n\n      Time conversion carried out by cpufreq when user space attempts to\n      read /sys/devices/system/cpu/cpu*/cpufreq/stats/time_in_state\n      won\u0027t work correcty if cputime_t doesn\u0027t map directly to jiffies.\n      Fix from Andreas Schwab.\n\n   9) Revert of a troublesome cpufreq commit\n\n      Commit 7c30ed5 (cpufreq: make sure frequency transitions are\n      serialized) was intended to address some known concurrency\n      problems in cpufreq related to the ordering of transitions, but\n      unfortunately it introduced several problems of its own, so I\n      decided to revert it now and address the original problems later\n      in a more robust way.\n\n  10) Intel Haswell CPU models for intel_pstate from Nell Hardcastle.\n\n  11) cpufreq fixes related to system suspend/resume\n\n      The recent cpufreq changes that made it preserve CPU sysfs\n      attributes over suspend/resume cycles introduced a possible NULL\n      pointer dereference that caused it to crash during the second\n      attempt to suspend.  Three commits from Srivatsa S Bhat fix that\n      problem and a couple of related issues.\n\n  12) cpufreq locking fix\n\n      cpufreq_policy_restore() should acquire the lock for reading, but\n      it acquires it for writing.  Fix from Lan Tianyu\"\n\n* tag \u0027pm+acpi-fixes-3.12-rc1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (25 commits)\n  cpufreq: Acquire the lock in cpufreq_policy_restore() for reading\n  cpufreq: Prevent problems in update_policy_cpu() if last_cpu \u003d\u003d new_cpu\n  cpufreq: Restructure if/else block to avoid unintended behavior\n  cpufreq: Fix crash in cpufreq-stats during suspend/resume\n  intel_pstate: Add Haswell CPU models\n  Revert \"cpufreq: make sure frequency transitions are serialized\"\n  cpufreq: Use signed type for \u0027ret\u0027 variable, to store negative error values\n  cpufreq: Remove temporary fix for race between CPU hotplug and sysfs-writes\n  cpufreq: Synchronize the cpufreq store_*() routines with CPU hotplug\n  cpufreq: Invoke __cpufreq_remove_dev_finish() after releasing cpu_hotplug.lock\n  cpufreq: Split __cpufreq_remove_dev() into two parts\n  cpufreq: Fix wrong time unit conversion\n  cpufreq: serialize calls to __cpufreq_governor()\n  cpufreq: don\u0027t allow governor limits to be changed when it is disabled\n  ACPI / bind: Prefer device objects with _STA to those without it\n  ACPI / hotplug / PCI: Avoid parent bus rescans on spurious device checks\n  ACPI / hotplug / PCI: Use _OST to notify firmware about notify status\n  ACPI / hotplug / PCI: Avoid doing too much for spurious notifies\n  ACPICA: Fix for a Store-\u003eArgX when ArgX contains a reference to a field.\n  ACPI / hotplug / PCI: Don\u0027t trim devices before scanning the namespace\n  ...\n"

      "message": "kprobes: unify insn caches\n\nThe current kpropes insn caches allocate memory areas for insn slots\nwith module_alloc().  The assumption is that the kernel image and module\narea are both within the same +/- 2GB memory area.\n\nThis however is not true for s390 where the kernel image resides within\nthe first 2GB (DMA memory area), but the module area is far away in the\nvmalloc area, usually somewhere close below the 4TB area.\n\nFor new pc relative instructions s390 needs insn slots that are within\n+/- 2GB of each area.  That way we can patch displacements of\npc-relative instructions within the insn slots just like x86 and\npowerpc.\n\nThe module area works already with the normal insn slot allocator,\nhowever there is currently no way to get insn slots that are within the\nfirst 2GB on s390 (aka DMA area).\n\nTherefore this patch set modifies the kprobes insn slot cache code in\norder to allow to specify a custom allocator for the insn slot cache\npages.  In addition architecure can now have private insn slot caches\nwithhout the need to modify common code.\n\nPatch 1 unifies and simplifies the current insn and optinsn caches\n        implementation. This is a preparation which allows to add more\n        insn caches in a simple way.\n\nPatch 2 adds the possibility to specify a custom allocator.\n\nPatch 3 makes s390 use the new insn slot mechanisms and adds support for\n        pc-relative instructions with long displacements.\n\nThis patch (of 3):\n\nThe two insn caches (insn, and optinsn) each have an own mutex and\nalloc/free functions (get_[opt]insn_slot() / free_[opt]insn_slot()).\n\nSince there is the need for yet another insn cache which satifies dma\nallocations on s390, unify and simplify the current implementation:\n\n- Move the per insn cache mutex into struct kprobe_insn_cache.\n- Move the alloc/free functions to kprobe.h so they are simply\n  wrappers for the generic __get_insn_slot/__free_insn_slot functions.\n  The implementation is done with a DEFINE_INSN_CACHE_OPS() macro\n  which provides the alloc/free functions for each cache if needed.\n- move the struct kprobe_insn_cache to kprobe.h which allows to generate\n  architecture specific insn slot caches outside of the core kprobes\n  code.\n\nSigned-off-by: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nCc: Masami Hiramatsu \u003cmasami.hiramatsu.pt@hitachi.com\u003e\nCc: Ananth N Mavinakayanahalli \u003cananth@in.ibm.com\u003e\nCc: Ingo Molnar \u003cmingo@kernel.org\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "fs: bump inode and dentry counters to long\n\nThis series reworks our current object cache shrinking infrastructure in\ntwo main ways:\n\n * Noticing that a lot of users copy and paste their own version of LRU\n   lists for objects, we put some effort in providing a generic version.\n   It is modeled after the filesystem users: dentries, inodes, and xfs\n   (for various tasks), but we expect that other users could benefit in\n   the near future with little or no modification.  Let us know if you\n   have any issues.\n\n * The underlying list_lru being proposed automatically and\n   transparently keeps the elements in per-node lists, and is able to\n   manipulate the node lists individually.  Given this infrastructure, we\n   are able to modify the up-to-now hammer called shrink_slab to proceed\n   with node-reclaim instead of always searching memory from all over like\n   it has been doing.\n\nPer-node lru lists are also expected to lead to less contention in the lru\nlocks on multi-node scans, since we are now no longer fighting for a\nglobal lock.  The locks usually disappear from the profilers with this\nchange.\n\nAlthough we have no official benchmarks for this version - be our guest to\nindependently evaluate this - earlier versions of this series were\nperformance tested (details at\nhttp://permalink.gmane.org/gmane.linux.kernel.mm/100537) yielding no\nvisible performance regressions while yielding a better qualitative\nbehavior in NUMA machines.\n\nWith this infrastructure in place, we can use the list_lru entry point to\nprovide memcg isolation and per-memcg targeted reclaim.  Historically,\nthose two pieces of work have been posted together.  This version presents\nonly the infrastructure work, deferring the memcg work for a later time,\nso we can focus on getting this part tested.  You can see more about the\nhistory of such work at http://lwn.net/Articles/552769/\n\nDave Chinner (18):\n  dcache: convert dentry_stat.nr_unused to per-cpu counters\n  dentry: move to per-sb LRU locks\n  dcache: remove dentries from LRU before putting on dispose list\n  mm: new shrinker API\n  shrinker: convert superblock shrinkers to new API\n  list: add a new LRU list type\n  inode: convert inode lru list to generic lru list code.\n  dcache: convert to use new lru list infrastructure\n  list_lru: per-node list infrastructure\n  shrinker: add node awareness\n  fs: convert inode and dentry shrinking to be node aware\n  xfs: convert buftarg LRU to generic code\n  xfs: rework buffer dispose list tracking\n  xfs: convert dquot cache lru to list_lru\n  fs: convert fs shrinkers to new scan/count API\n  drivers: convert shrinkers to new count/scan API\n  shrinker: convert remaining shrinkers to count/scan API\n  shrinker: Kill old -\u003eshrink API.\n\nGlauber Costa (7):\n  fs: bump inode and dentry counters to long\n  super: fix calculation of shrinkable objects for small numbers\n  list_lru: per-node API\n  vmscan: per-node deferred work\n  i915: bail out earlier when shrinker cannot acquire mutex\n  hugepage: convert huge zero page shrinker to new shrinker API\n  list_lru: dynamically adjust node arrays\n\nThis patch:\n\nThere are situations in very large machines in which we can have a large\nquantity of dirty inodes, unused dentries, etc.  This is particularly true\nwhen umounting a filesystem, where eventually since every live object will\neventually be discarded.\n\nDave Chinner reported a problem with this while experimenting with the\nshrinker revamp patchset.  So we believe it is time for a change.  This\npatch just moves int to longs.  Machines where it matters should have a\nbig long anyway.\n\nSigned-off-by: Glauber Costa \u003cglommer@openvz.org\u003e\nCc: Dave Chinner \u003cdchinner@redhat.com\u003e\nCc: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nCc: Adrian Hunter \u003cadrian.hunter@intel.com\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Artem Bityutskiy \u003cartem.bityutskiy@linux.intel.com\u003e\nCc: Arve Hjønnevåg \u003carve@android.com\u003e\nCc: Carlos Maiolino \u003ccmaiolino@redhat.com\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nCc: Daniel Vetter \u003cdaniel.vetter@ffwll.ch\u003e\nCc: Dave Chinner \u003cdchinner@redhat.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Gleb Natapov \u003cgleb@redhat.com\u003e\nCc: Greg Thelen \u003cgthelen@google.com\u003e\nCc: J.

But the newly\nintroduced code doesn\u0027t do so, it returns 0 instead of 1.\n\nThis introduces performance regression, reported by Dave Chinner:\n\n                        v4 filesystem           v5 filesystem\n3.11+xfsdev:            220k files/s            225k files/s\n3.12-git                180k files/s            185k files/s\n3.12-git-revert         245k files/s            247k files/s\n\nYou can find more detailed information at:\n\n  https://lkml.org/lkml/2013/9/10/1\n\nThis patch corrects the return value of should_we_balance()\nfunction as orignally intended.\n\nWith this patch, Dave Chinner reports that the regression is gone:\n\n                        v4 filesystem           v5 filesystem\n3.11+xfsdev:            220k files/s            225k files/s\n3.12-git                180k files/s            185k files/s\n3.12-git-revert         245k files/s            247k files/s\n3.12-git-fix            249k files/s            248k files/s\n\nReported-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nTested-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nSigned-off-by: Joonsoo Kim \u003ciamjoonsoo.kim@lge.com\u003e\nCc: Paul Turner \u003cpjt@google.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Dave Chinner \u003cdavid@fromorbit.com\u003e\nLink: http://lkml.kernel.org/r/20130910065448.GA20368@lge.com\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\n"

Most changes aren\u0027t visible\n  to userland at all at this point and are laying foundation for the\n  planned unified hierarchy.\n\n   - The biggest change is decoupling the lifetime management of css\n     (cgroup_subsys_state) from that of cgroup\u0027s.  Because controllers\n     (cpu, memory, block and so on) will need to be dynamically enabled\n     and disabled, css which is the association point between a cgroup\n     and a controller may come and go dynamically across the lifetime of\n     a cgroup.  Till now, css\u0027s were created when the associated cgroup\n     was created and stayed till the cgroup got destroyed.\n\n     Assumptions around this tight coupling permeated through cgroup\n     core and controllers.  These assumptions are gradually removed,\n     which consists bulk of patches, and css destruction path is\n     completely decoupled from cgroup destruction path.  Note that\n     decoupling of creation path is relatively easy on top of these\n     changes and the patchset is pending for the next window.\n\n   - cgroup has its own event mechanism cgroup.event_control, which is\n     only used by memcg.  It is overly complex trying to achieve high\n     flexibility whose benefits seem dubious at best.  Going forward,\n     new events will simply generate file modified event and the\n     existing mechanism is being made specific to memcg.

That is, when only one callback is registered to the function\ntracer, it gets called directly by the mcount trampoline. But if this\nfunction has filters, it may be called by the wrong functions.\n\nAs the list ops callback that handles multiple callbacks that are\nregistered to ftrace, it also handles what functions they call. While\nthe transaction is taking place, use the list function always, and\nafter all the updates are finished (only the functions that should be\ntraced are being traced), then we can update the trampoline to call\nthe function directly.\n\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n"

This also should make ACPIPHP work in\n    some cases in which it was known to have problems.  From\n    Rafael J Wysocki, Mika Westerberg and Kirill A Shutemov.\n\n 2) ACPI core code cleanups and dock station support cleanups from\n    Jiang Liu and Rafael J Wysocki.\n\n 3) Fixes for locking problems related to ACPI device hotplug from\n    Rafael J Wysocki.\n\n 4) ACPICA update to version 20130725 includig fixes, cleanups, support\n    for more than 256 GPEs per GPE block and a change to make the ACPI\n    PM Timer optional (we\u0027ve seen systems without the PM Timer in the\n    field already).  One of the fixes, related to the DeRefOf operator,\n    is necessary to prevent some Windows 8 oriented AML from causing\n    problems to happen.  From Bob Moore, Lv Zheng, and Jung-uk Kim.\n\n 5) Removal of the old and long deprecated /proc/acpi/event interface\n    and related driver changes from Thomas Renninger.\n\n 6) ACPI and Xen changes to make the reduced hardware sleep work with\n    the latter from Ben Guthro.\n\n 7) ACPI video driver cleanups and a blacklist of systems that should\n    not tell the BIOS that they are compatible with Windows 8 (or ACPI\n    backlight and possibly other things will not work on them).  From\n    Felipe Contreras.\n\n 8) Assorted ACPI fixes and cleanups from Aaron Lu, Hanjun Guo,\n    Kuppuswamy Sathyanarayanan, Lan Tianyu, Sachin Kamat, Tang Chen,\n    Toshi Kani, and Wei Yongjun.\n\n 9) cpufreq ondemand governor target frequency selection change to\n    reduce oscillations between min and max frequencies (essentially,\n    it causes the governor to choose target frequencies proportional\n    to load) from Stratos Karafotis.\n\n10) cpufreq fixes allowing sysfs attributes file permissions to be\n    preserved over suspend/resume cycles Srivatsa S Bhat.\n\n11) Removal of Device Tree parsing for CPU device nodes from multiple\n    cpufreq drivers that required some changes related to\n    of_get_cpu_node() to be made in a few architectures and in the\n    driver core.  From Sudeep KarkadaNagesha.\n\n12) cpufreq core fixes and cleanups related to mutual exclusion and\n    driver module references from Viresh Kumar, Lukasz Majewski and\n    Rafael J Wysocki.\n\n13) Assorted cpufreq fixes and cleanups from Amit Daniel Kachhap,\n    Bartlomiej Zolnierkiewicz, Hanjun Guo, Jingoo Han, Joseph Lo,\n    Julia Lawall, Li Zhong, Mark Brown, Sascha Hauer, Stephen Boyd,\n    Stratos Karafotis, and Viresh Kumar.\n\n14) Fixes to prevent race conditions in coupled cpuidle from happening\n    from Colin Cross.\n\n15) cpuidle core fixes and cleanups from Daniel Lezcano and\n    Tuukka Tikkanen.\n\n16) Assorted cpuidle fixes and cleanups from Daniel Lezcano,\n    Geert Uytterhoeven, Jingoo Han, Julia Lawall, Linus Walleij,\n    and Sahara.\n\n17) System sleep tracing changes from Todd E Brandt and Shuah Khan.\n\n18) PNP subsystem conversion to using struct dev_pm_ops for power\n    management from Shuah Khan.\n\n* tag \u0027pm+acpi-3.12-rc1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (217 commits)\n  cpufreq: Don\u0027t use smp_processor_id() in preemptible context\n  cpuidle: coupled: fix race condition between pokes and safe state\n  cpuidle: coupled: abort idle if pokes are pending\n  cpuidle: coupled: disable interrupts after entering safe state\n  ACPI / hotplug: Remove containers synchronously\n  driver core / ACPI: Avoid device hot remove locking issues\n  cpufreq: governor: Fix typos in comments\n  cpufreq: governors: Remove duplicate check of target freq in supported range\n  cpufreq: Fix timer/workqueue corruption due to double queueing\n  ACPI / EC: Add ASUSTEK L4R to quirk list in order to validate ECDT\n  ACPI / thermal: Add check of \"_TZD\" availability and evaluating result\n  cpufreq: imx6q: Fix clock enable balance\n  ACPI: blacklist win8 OSI for buggy laptops\n  cpufreq: tegra: fix the wrong clock name\n  cpuidle: Change struct menu_device field types\n  cpuidle: Add a comment warning about possible overflow\n  cpuidle: Fix variable domains in get_typical_interval()\n  cpuidle: Fix menu_device-\u003eintervals type\n  cpuidle: CodingStyle: Break up multiple assignments on single line\n  cpuidle: Check called function parameter in get_typical_interval()\n  ...\n"
