      "message": "PM / Sleep: Introduce \"late suspend\" and \"early resume\" of devices\n\nThe current device suspend/resume phases during system-wide power\ntransitions appear to be insufficient for some platforms that want\nto use the same callback routines for saving device states and\nrelated operations during runtime suspend/resume as well as during\nsystem suspend/resume.  In principle, they could point their\n.suspend_noirq() and .resume_noirq() to the same callback routines\nas their .runtime_suspend() and .runtime_resume(), respectively,\nbut at least some of them require device interrupts to be enabled\nwhile the code in those routines is running.\n\nIt also makes sense to have device suspend-resume callbacks that will\nbe executed with runtime PM disabled and with device interrupts\nenabled in case someone needs to run some special code in that\ncontext during system-wide power transitions.\n\nApart from this, .suspend_noirq() and .resume_noirq() were introduced\nas a workaround for drivers using shared interrupts and failing to\nprevent their interrupt handlers from accessing suspended hardware.\nIt appears to be better not to use them for other porposes, or we may\nhave to deal with some serious confusion (which seems to be happening\nalready).\n\nFor the above reasons, introduce new device suspend/resume phases,\n\"late suspend\" and \"early resume\" (and analogously for hibernation)\nwhose callback will be executed with runtime PM disabled and with\ndevice interrupts enabled and whose callback pointers generally may\npoint to runtime suspend/resume routines.\n\nSigned-off-by: Rafael J.

However,\nthat also would cause the hibernate interfaces for user space to be\nenabled, which might confuse user space, because the Xen kernels\ndon\u0027t support hibernation.  Moreover, it would be wasteful, as it\nwould make the Xen kernels include a substantial amount of code that\nthey would never use.\n\nTo address this issue introduce new power management Kconfig option\nCONFIG_HIBERNATE_CALLBACKS, such that it will only select the code\nthat is necessary for the hibernate device callbacks to work and make\nCONFIG_HIBERNATION select it.  Then, Xen save/restore will be able to\nselect CONFIG_HIBERNATE_CALLBACKS without dragging the entire\nhibernate code along with 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"

When the suspend\nprocess calls xs_suspend it tries to take the request_mutex but if a write is\nin progress it could be looping in xenbus_xs.c:read_reply() waiting for\nsomething to arrive on \u0026xs_state.reply_list while holding the request_mutex\n(taken in the caller of read_reply).\n\nHowever if we have done dpm_suspend_noirq before xs_suspend then we won\u0027t get\nany more xenstore interrupts and process_msg() will never be woken up to add\nanything to the reply_list.\n\nFix this by calling xs_suspend before dpm_suspend_noirq. If dpm_suspend_noirq\nfails then make sure we go through the xs_suspend_cancel() code path.\n\nSigned-off-by: Ian Campbell \u003cian.campbell@citrix.com\u003e\nAcked-by: Jeremy Fitzhardinge \u003cjeremy.fitzhardinge@citrix.com\u003e\nCc: Stable Kernel \u003cstable@kernel.org\u003e\n"
