Those same\nfilesystems use memory shrinkers that may be triggered by the\nhibernate memory preallocation.  If those memory shrinkers wait for\nthe frozen kernel threads, the hibernate process deadlocks (this\nhappens with XFS, for one example).\n\nApparently, it is not technically viable to redesign the filesystems\nin question to avoid the situation described above, so the only\npossible solution of this issue is to defer the freezing of kernel\nthreads until the hibernate memory preallocation is done, which is\nimplemented by this change.\n\nUnfortunately, this requires the memory preallocation to be done\nbefore the \"prepare\" stage of device freeze, so after this change the\nonly way drivers can allocate additional memory for their freeze\nroutines in a clean way is to use PM notifiers.\n\nReported-by: Christoph \u003ccr2005@u-club.de\u003e\nSigned-off-by: Rafael J.

      "message": "PM: Allow drivers to allocate memory from .prepare() callbacks safely\n\nIf device drivers allocate substantial amounts of memory (above 1 MB)\nin their hibernate .freeze() callbacks (or in their legacy suspend\ncallbcks during hibernation), the subsequent creation of hibernate\nimage may fail due to the lack of memory.  This is the case, because\nthe drivers\u0027 .freeze() callbacks are executed after the hibernate\nmemory preallocation has been carried out and the preallocated amount\nof memory may be too small to cover the new driver allocations.\nUnfortunately, the drivers\u0027 .prepare() callbacks also are executed\nafter the hibernate memory preallocation has completed, so they are\nnot suitable for allocating additional memory either.  Thus the only\nway a driver can safely allocate memory during hibernation is to use\na hibernate/suspend notifier.  However, the notifiers are called\nbefore the freezing of user space and the drivers wanting to use them\nfor allocating additional memory may not know how much memory needs\nto be allocated at that point.\n\nTo let device drivers overcome this difficulty rework the hibernation\nsequence so that the memory preallocation is carried out after the\ndrivers\u0027 .prepare() callbacks have been executed, so that the\n.prepare() callbacks can be used for allocating additional memory\nto be used by the drivers\u0027 .freeze() callbacks.  Update documentation\nto match the new behavior of the code.\n\nSigned-off-by: Rafael J. Wysocki \u003crjw@sisk.pl\u003e\n"

      "message": "PM / Hibernate: Add sysfs knob to control size of memory for drivers\n\nMartin reports that on his system hibernation occasionally fails due\nto the lack of memory, because the radeon driver apparently allocates\ntoo much of it during the device freeze stage.  It turns out that the\namount of memory allocated by radeon during hibernation (and\npresumably during system suspend too) depends on the utilization of\nthe GPU (e.g. hibernating while there are two KDE 4 sessions with\ncompositing enabled causes radeon to allocate more memory than for\none KDE 4 session).\n\nIn principle it should be possible to use image_size to make the\nmemory preallocation mechanism free enough memory for the radeon\ndriver, but in practice it is not easy to guess the right value\nbecause of the way the preallocation code uses image_size.  For this\nreason, it seems reasonable to allow users to control the amount of\nmemory reserved for driver allocations made after the hibernate\npreallocation, which currently is constant and amounts to 1 MB.\n\nIntroduce a new sysfs file, /sys/power/reserved_size, whose value\nwill be used as the amount of memory to reserve for the\npost-preallocation reservations made by device drivers, in bytes.\nFor backwards compatibility, set its default (and initial) value to\nthe currently used number (1 MB).\n\nReferences: https://bugzilla.kernel.org/show_bug.cgi?id\u003d34102\nReported-and-tested-by: Martin Steigerwald \u003cMartin@Lichtvoll.de\u003e\nSigned-off-by: Rafael J.

It complicated matters by\nadding a second swap allocation path, just for hibernation; without in any\nway fixing the issue that it was intended to address - page reclaim after\nfixing the hibernation image might free swap from a page already imaged as\nswapcache, letting its swap be reallocated to store a different page of\nthe image: resulting in data corruption if the imaged page were freed as\nclean then swapped back in.  Pages freed to si-\u003eswap_map were still in\ndanger of being reallocated by the alternative allocation path.\n\nI guess it inadvertently fixed slow SSD swap allocation for hibernation,\nas reported by Nigel Cunningham: by missing out the discards that occur on\nthe usual swap allocation path; but that was unintentional, and needs a\nseparate fix.\n\nSigned-off-by: Hugh Dickins \u003chughd@google.com\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: \"Rafael J.

      "message": "PM: Make it possible to avoid races between wakeup and system sleep\n\nOne of the arguments during the suspend blockers discussion was that\nthe mainline kernel didn\u0027t contain any mechanisms making it possible\nto avoid races between wakeup and system suspend.\n\nGenerally, there are two problems in that area.  First, if a wakeup\nevent occurs exactly when /sys/power/state is being written to, it\nmay be delivered to user space right before the freezer kicks in, so\nthe user space consumer of the event may not be able to process it\nbefore the system is suspended.  Second, if a wakeup event occurs\nafter user space has been frozen, it is not generally guaranteed that\nthe ongoing transition of the system into a sleep state will be\naborted.\n\nTo address these issues introduce a new global sysfs attribute,\n/sys/power/wakeup_count, associated with a running counter of wakeup\nevents and three helper functions, pm_stay_awake(), pm_relax(), and\npm_wakeup_event(), that may be used by kernel subsystems to control\nthe behavior of this attribute and to request the PM core to abort\nsystem transitions into a sleep state already in progress.\n\nThe /sys/power/wakeup_count file may be read from or written to by\nuser space.  Reads will always succeed (unless interrupted by a\nsignal) and return the current value of the wakeup events counter.\nWrites, however, will only succeed if the written number is equal to\nthe current value of the wakeup events counter.  If a write is\nsuccessful, it will cause the kernel to save the current value of the\nwakeup events counter and to abort the subsequent system transition\ninto a sleep state if any wakeup events are reported after the write\nhas returned.\n\n[The assumption is that before writing to /sys/power/state user space\nwill first read from /sys/power/wakeup_count.  Next, user space\nconsumers of wakeup events will have a chance to acknowledge or\nveto the upcoming system transition to a sleep state.  Finally, if\nthe transition is allowed to proceed, /sys/power/wakeup_count will\nbe written to and if that succeeds, /sys/power/state will be written\nto as well.  Still, if any wakeup events are reported to the PM core\nby kernel subsystems after that point, the transition will be\naborted.]\n\nAdditionally, put a wakeup events counter into struct dev_pm_info and\nmake these per-device wakeup event counters available via sysfs,\nso that it\u0027s possible to check the activity of various wakeup event\nsources within the kernel.\n\nTo illustrate how subsystems can use pm_wakeup_event(), make the\nlow-level PCI runtime PM wakeup-handling code use it.\n\nSigned-off-by: Rafael J.

      "message": "include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h\n\npercpu.h is included by sched.h and module.h and thus ends up being\nincluded when building most .c files.  percpu.h includes slab.h which\nin turn includes gfp.h making everything defined by the two files\nuniversally available and complicating inclusion dependencies.\n\npercpu.h -\u003e slab.h dependency is about to be removed.  Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability.  As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n  http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n  only the necessary includes are there.  ie. if only gfp is used,\n  gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n  blocks and try to put the new include such that its order conforms\n  to its surrounding.  It\u0027s put in the include block which contains\n  core kernel includes, in the same order that the rest are ordered -\n  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n  doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n  because the file doesn\u0027t have fitting include block), it prints out\n  an error message indicating which .h file needs to be added to the\n  file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n   over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n   and ~3000 slab.h inclusions.  The script emitted errors for ~400\n   files.\n\n2. Each error was manually checked.  Some didn\u0027t need the inclusion,\n   some needed manual addition while adding it to implementation .h or\n   embedding .c file was more appropriate for others.  This step added\n   inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n   from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n   e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n   APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n   editing them as sprinkling gfp.h and slab.h inclusions around .h\n   files could easily lead to inclusion dependency hell.  Most gfp.h\n   inclusion directives were ignored as stuff from gfp.h was usually\n   wildly available and often used in preprocessor macros.  Each\n   slab.h inclusion directive was examined and added manually as\n   necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my\n   distributed build env didn\u0027t work with gcov compiles) and a few\n   more options had to be turned off depending on archs to make things\n   build (like ipr on powerpc/64 which failed due to missing writeq).\n\n   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n   * powerpc and powerpc64 SMP allmodconfig\n   * sparc and sparc64 SMP allmodconfig\n   * ia64 SMP allmodconfig\n   * s390 SMP allmodconfig\n   * alpha SMP allmodconfig\n   * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n   a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n"

      "message": "Suspend-related patches for 2.6.27\n\nACPI PM: Add possibility to change suspend sequence\n\nThere are some systems out there that don\u0027t work correctly with\nour current suspend/hibernation code ordering.  Provide a workaround\nfor these systems allowing them to pass \u0027acpi_sleep\u003dold_ordering\u0027 in\nthe kernel command line so that it will use the pre-ACPI 2.0 (\"old\")\nsuspend code ordering.\n\nUnfortunately, this requires us to add a platform hook to the\nresuming of devices for recovering the platform in case one of the\ndevice drivers\u0027 .suspend() routines returns error code.  Namely,\nACPI 1.0 specifies that _PTS should be called before suspending\ndevices, but _WAK still should be called before resuming them in\norder to undo the changes made by _PTS.  However, if there is an\nerror during suspending devices, they are automatically resumed\nwithout returning control to the PM core, so the _WAK has to be\ncalled from within device_resume() in that cases.\n\nThe patch also reorders and refactors the ACPI suspend/hibernation\ncode to avoid duplication as far as reasonably possible.\n\nSigned-off-by: Rafael J.

This has been requested for multiple\ntimes by many people, including Linus himself, and the reason is that\nwithin the current scheme if -\u003eresume() is called, for example, it\u0027s\ndifficult to say why it\u0027s been called (ie. is it a resume from RAM or\nfrom hibernation or a suspend/hibernation failure etc.?).\n\nThe second purpose is to make the suspend/hibernation callbacks more\nflexible so that device drivers can handle more than they can within\nthe current scheme.  For example, some drivers may need to prevent\nnew children of the device from being registered before their\n-\u003esuspend() callbacks are executed or they may want to carry out some\noperations requiring the availability of some other devices, not\ndirectly bound via the parent-child relationship, in order to prepare\nfor the execution of -\u003esuspend(), etc.\n\nUltimately, we\u0027d like to stop using the freezing of tasks for suspend\nand therefore the drivers\u0027 suspend/hibernation code will have to take\ncare of the handling of the user space during suspend/hibernation.\nThat, in turn, would be difficult within the current scheme, without\nthe new -\u003eprepare() and -\u003ecomplete() callbacks.\n\nSigned-off-by: Rafael J.
