      "message": "walk system ram range\n\nOriginally, walk_memory_resource() was introduced to traverse all memory\nof \"System RAM\" for detecting memory hotplug/unplug range.  For doing so,\nflags of IORESOUCE_MEM|IORESOURCE_BUSY was used and this was enough for\nmemory hotplug.\n\nBut for using other purpose, /proc/kcore, this may includes some firmware\narea marked as IORESOURCE_BUSY | IORESOUCE_MEM.  This patch makes the\ncheck strict to find out busy \"System RAM\".\n\nNote: PPC64 keeps their own walk_memory_resouce(), which walk through\nppc64\u0027s lmb informaton.  Because old kclist_add() is called per lmb, this\npatch makes no difference in behavior, finally.\n\nAnd this patch removes CONFIG_MEMORY_HOTPLUG check from this function.\nBecause pfn_valid() just show \"there is memmap or not* and cannot be used\nfor \"there is physical memory or not\", this function is useful in generic\nto scan physical memory range.\n\nSigned-off-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: WANG Cong \u003cxiyou.wangcong@gmail.com\u003e\nCc: Américo Wang \u003cxiyou.wangcong@gmail.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

But you get no\ninformation about the consumed stack memory of the the threads.\n\nThere is an enhancement in the /proc/\u003cpid\u003e/{task/*,}/*maps and which marks\nthe vm mapping where the thread stack pointer reside with \"[thread stack\nxxxxxxxx]\".  xxxxxxxx is the maximum size of stack.  This is a value\ninformation, because libpthread doesn\u0027t set the start of the stack to the\ntop of the mapped area, depending of the pthread usage.\n\nA sample output of /proc/\u003cpid\u003e/task/\u003ctid\u003e/maps looks like:\n\n08048000-08049000 r-xp 00000000 03:00 8312       /opt/z\n08049000-0804a000 rw-p 00001000 03:00 8312       /opt/z\n0804a000-0806b000 rw-p 00000000 00:00 0          [heap]\na7d12000-a7d13000 ---p 00000000 00:00 0\na7d13000-a7f13000 rw-p 00000000 00:00 0          [thread stack: 001ff4b4]\na7f13000-a7f14000 ---p 00000000 00:00 0\na7f14000-a7f36000 rw-p 00000000 00:00 0\na7f36000-a8069000 r-xp 00000000 03:00 4222       /lib/libc.so.6\na8069000-a806b000 r--p 00133000 03:00 4222       /lib/libc.so.6\na806b000-a806c000 rw-p 00135000 03:00 4222       /lib/libc.so.6\na806c000-a806f000 rw-p 00000000 00:00 0\na806f000-a8083000 r-xp 00000000 03:00 14462      /lib/libpthread.so.0\na8083000-a8084000 r--p 00013000 03:00 14462      /lib/libpthread.so.0\na8084000-a8085000 rw-p 00014000 03:00 14462      /lib/libpthread.so.0\na8085000-a8088000 rw-p 00000000 00:00 0\na8088000-a80a4000 r-xp 00000000 03:00 8317       /lib/ld-linux.so.2\na80a4000-a80a5000 r--p 0001b000 03:00 8317       /lib/ld-linux.so.2\na80a5000-a80a6000 rw-p 0001c000 03:00 8317       /lib/ld-linux.so.2\nafaf5000-afb0a000 rw-p 00000000 00:00 0          [stack]\nffffe000-fffff000 r-xp 00000000 00:00 0          [vdso]\n\nAlso there is a new entry \"stack usage\" in /proc/\u003cpid\u003e/{task/*,}/status\nwhich will you give the current stack usage in kb.\n\nA sample output of /proc/self/status looks like:\n\nName:\tcat\nState:\tR (running)\nTgid:\t507\nPid:\t507\n.\n.\n.\nCapBnd:\tfffffffffffffeff\nvoluntary_ctxt_switches:\t0\nnonvoluntary_ctxt_switches:\t0\nStack usage:\t12 kB\n\nI also fixed stack base address in /proc/\u003cpid\u003e/{task/*,}/stat to the base\naddress of the associated thread stack and not the one of the main\nprocess.

      "message": "proc connector: add event for process becoming session leader\n\nThe act of a process becoming a session leader is a useful signal to a\nsupervising init daemon such as Upstart.\n\nWhile a daemon will normally do this as part of the process of becoming a\ndaemon, it is rare for its children to do so.  When the children do, it is\nnearly always a sign that the child should be considered detached from the\nparent and not supervised along with it.\n\nThe poster-child example is OpenSSH; the per-login children call setsid()\nso that they may control the pty connected to them.  If the primary daemon\ndies or is restarted, we do not want to consider the per-login children\nand want to respawn the primary daemon without killing the children.\n\nThis patch adds a new PROC_SID_EVENT and associated structure to the\nproc_event event_data union, it arranges for this to be emitted when the\nspecial PIDTYPE_SID pid is set.\n\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: Scott James Remnant \u003cscott@ubuntu.com\u003e\nAcked-by: Matt Helsley \u003cmatthltc@us.ibm.com\u003e\nCc: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Evgeniy Polyakov \u003cjohnpol@2ka.mipt.ru\u003e\nAcked-by: \"David S.

      "message": "ksm: fix deadlock with munlock in exit_mmap\n\nRawhide users have reported hang at startup when cryptsetup is run: the\nsame problem can be simply reproduced by running a program int main() {\nmlockall(MCL_CURRENT | MCL_FUTURE); return 0; }\n\nThe problem is that exit_mmap() applies munlock_vma_pages_all() to\nclean up VM_LOCKED areas, and its current implementation (stupidly)\ntries to fault in absent pages, for example where PROT_NONE prevented\nthem being faulted in when mlocking.  Whereas the \"ksm: fix oom\ndeadlock\" patch, knowing there\u0027s a race by which KSM might try to fault\nin pages after exit_mmap() had finally zapped the range, backs out of\nsuch faults doing nothing when its ksm_test_exit() notices mm_users 0.\n\nSo revert that part of \"ksm: fix oom deadlock\" which moved the\nksm_exit() call from before exit_mmap() to the middle of exit_mmap();\nand remove those ksm_test_exit() checks from the page fault paths, so\nallowing the munlocking to proceed without interference.\n\nksm_exit, if there are rmap_items still chained on this mm slot, takes\nmmap_sem write side: so preventing KSM from working on an mm while\nexit_mmap runs.  And KSM will bail out as soon as it notices that\nmm_users is already zero, thanks to its internal ksm_test_exit checks.\nSo that when a task is killed by OOM killer or the user, KSM will not\nindefinitely prevent it from running exit_mmap to release its memory.\n\nThis does break a part of what \"ksm: fix oom deadlock\" was trying to\nachieve.  When unmerging KSM (echo 2 \u003e/sys/kernel/mm/ksm), and even\nwhen ksmd itself has to cancel a KSM page, it is possible that the\nfirst OOM-kill victim would be the KSM process being faulted: then its\nmemory won\u0027t be freed until a second victim has been selected (freeing\nmemory for the unmerging fault to complete).\n\nBut the OOM killer is already liable to kill a second victim once the\nintended victim\u0027s p-\u003emm goes to NULL: so there\u0027s not much point in\nrejecting this KSM patch before fixing that OOM behaviour.  It is very\nmuch more important to allow KSM users to boot up, than to haggle over\nan unlikely and poorly supported OOM case.\n\nWe also intend to fix munlocking to not fault pages: at which point\nthis patch _could_ be reverted; though that would be controversial, so\nwe hope to find a better solution.\n\nSigned-off-by: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nAcked-by: Justin M.

And bumping mm_users won\u0027t\nhelp at all, that just ensures that the pages the OOM killer assumes\nare on their way to being freed will not be freed.\n\nThe best answer seems to be, to move the ksm_exit callout from just\nbefore exit_mmap, to the middle of exit_mmap: after the mm\u0027s pages\nhave been freed (if the mmu_gather is flushed), but before its page\ntables and vma structures have been freed; and down_write,up_write\nmmap_sem there to serialize with KSM\u0027s own reliance on mmap_sem.\n\nBut KSM then needs to be careful, whenever it downs mmap_sem, to\ncheck that the mm is not already exiting: there\u0027s a danger of using\nfind_vma on a layout that\u0027s being torn apart, or writing into page\ntables which have been freed for reuse; and even do_anonymous_page\nand __do_fault need to check they\u0027re not being called by break_ksm\nto reinstate a pte after zap_pte_range has zapped that page table.\n\nThough it might be clearer to add an exiting flag, set while holding\nmmap_sem in __ksm_exit, that wouldn\u0027t cover the issue of reinstating\na zapped pte.  All we need is to check whether mm_users is 0 - but\nmust remember that ksmd may detect that before __ksm_exit is reached.\nSo, ksm_test_exit(mm) added to comment such checks on mm-\u003emm_users.\n\n__ksm_exit now has to leave clearing up the rmap_items to ksmd,\nthat needs ksm_thread_mutex; but shift the exiting mm just after the\nksm_scan cursor so that it will soon be dealt with.  __ksm_enter raise\nmm_count to hold the mm_struct, ksmd\u0027s exit processing (exactly like\nits processing when it finds all VM_MERGEABLEs unmapped) mmdrop it,\nsimilar procedure for KSM_RUN_UNMERGE (which has stopped ksmd).\n\nBut also give __ksm_exit a fast path: when there\u0027s no complication\n(no rmap_items attached to mm and it\u0027s not at the ksm_scan cursor),\nit can safely do all the exiting work itself.  This is not just an\noptimization: when ksmd is not running, the raised mm_count would\notherwise leak mm_structs.\n\nSigned-off-by: Hugh Dickins \u003chugh.dickins@tiscali.co.uk\u003e\nAcked-by: Izik Eidus \u003cieidus@redhat.com\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "perf: Do the big rename: Performance Counters -\u003e Performance Events\n\nBye-bye Performance Counters, welcome Performance Events!\n\nIn the past few months the perfcounters subsystem has grown out its\ninitial role of counting hardware events, and has become (and is\nbecoming) a much broader generic event enumeration, reporting, logging,\nmonitoring, analysis facility.\n\nNaming its core object \u0027perf_counter\u0027 and naming the subsystem\n\u0027perfcounters\u0027 has become more and more of a misnomer. With pending\ncode like hw-breakpoints support the \u0027counter\u0027 name is less and\nless appropriate.\n\nAll in one, we\u0027ve decided to rename the subsystem to \u0027performance\nevents\u0027 and to propagate this rename through all fields, variables\nand API names. (in an ABI compatible fashion)\n\nThe word \u0027event\u0027 is also a bit shorter than \u0027counter\u0027 - which makes\nit slightly more convenient to write/handle as well.\n\nThanks goes to Stephane Eranian who first observed this misnomer and\nsuggested a rename.\n\nUser-space tooling and ABI compatibility is not affected - this patch\nshould be function-invariant. (Also, defconfigs were not touched to\nkeep the size down.)\n\nThis patch has been generated via the following script:\n\n  FILES\u003d$(find * -type f | grep -vE \u0027oprofile|[^K]config\u0027)\n\n  sed -i \\\n    -e \u0027s/PERF_EVENT_/PERF_RECORD_/g\u0027 \\\n    -e \u0027s/PERF_COUNTER/PERF_EVENT/g\u0027 \\\n    -e \u0027s/perf_counter/perf_event/g\u0027 \\\n    -e \u0027s/nb_counters/nb_events/g\u0027 \\\n    -e \u0027s/swcounter/swevent/g\u0027 \\\n    -e \u0027s/tpcounter_event/tp_event/g\u0027 \\\n    $FILES\n\n  for N in $(find . -name perf_counter.[ch]); do\n    M\u003d$(echo $N | sed \u0027s/perf_counter/perf_event/g\u0027)\n    mv $N $M\n  done\n\n  FILES\u003d$(find . -name perf_event.*)\n\n  sed -i \\\n    -e \u0027s/COUNTER_MASK/REG_MASK/g\u0027 \\\n    -e \u0027s/COUNTER/EVENT/g\u0027 \\\n    -e \u0027s/\\\u003cevent\\\u003e/event_id/g\u0027 \\\n    -e \u0027s/counter/event/g\u0027 \\\n    -e \u0027s/Counter/Event/g\u0027 \\\n    $FILES\n\n... to keep it as correct as possible. This script can also be\nused by anyone who has pending perfcounters patches - it converts\na Linux kernel tree over to the new naming. We tried to time this\nchange to the point in time where the amount of pending patches\nis the smallest: the end of the merge window.\n\nNamespace clashes were fixed up in a preparatory patch - and some\nstylistic fallout will be fixed up in a subsequent patch.\n\n( NOTE: \u0027counters\u0027 are still the proper terminology when we deal\n  with hardware registers - and these sed scripts are a bit\n  over-eager in renaming them. I\u0027ve undone some of that, but\n  in case there\u0027s something left where \u0027counter\u0027 would be\n  better than \u0027event\u0027 we can undo that on an individual basis\n  instead of touching an otherwise nicely automated patch. )\n\nSuggested-by: Stephane Eranian \u003ceranian@google.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nReviewed-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: \"David S.
