      "message": "x86, nmi_watchdog: Remove ARCH_HAS_NMI_WATCHDOG and rely on CONFIG_HARDLOCKUP_DETECTOR\n\nThe x86 arch has shifted its use of the nmi_watchdog from a\nlocal implementation to the global one provide by\nkernel/watchdog.c.  This shift has caused a whole bunch of\ncompile problems under different config options.  I attempt to\nsimplify things with the patch below.\n\nIn order to simplify things, I had to come to terms with the\nmeaning of two terms ARCH_HAS_NMI_WATCHDOG and\nCONFIG_HARDLOCKUP_DETECTOR.  Basically they mean the same thing,\nthe former on a local level and the latter on a global level.\n\nWith the old x86 nmi watchdog gone, there is no need to rely on\ndefining the ARCH_HAS_NMI_WATCHDOG variable because it doesn\u0027t\nmake sense any more.  x86 will now use the global\nimplementation.\n\nThe changes below do a few things.  First it changes the few\nplaces that relied on ARCH_HAS_NMI_WATCHDOG to use\nCONFIG_X86_LOCAL_APIC (the former was an alias for the latter\nanyway, so nothing unusual here).  Those pieces of code were\nrelying more on local apic functionality the nmi watchdog\nfunctionality, so the change should make sense.\n\nSecond, I removed the x86 implementation of\ntouch_nmi_watchdog().  It isn\u0027t need now, instead x86 will rely\non kernel/watchdog.c\u0027s implementation.\n\nThird, I removed the #define ARCH_HAS_NMI_WATCHDOG itself from\nx86.  And tweaked the include/linux/nmi.h file to tell users to\nlook for an externally defined touch_nmi_watchdog in the case of\nARCH_HAS_NMI_WATCHDOG _or_ CONFIG_HARDLOCKUP_DETECTOR. This\nchanges removes some of the ugliness in that file.\n\nFinally, I added a Kconfig dependency for\nCONFIG_HARDLOCKUP_DETECTOR that said you can\u0027t have\nARCH_HAS_NMI_WATCHDOG _and_ CONFIG_HARDLOCKUP_DETECTOR.  You can\nonly have one nmi_watchdog.\n\nTested with\nARCH\u003di386: allnoconfig, defconfig, allyesconfig, (various broken\nconfigs) ARCH\u003dx86_64: allnoconfig, defconfig, allyesconfig,\n(various broken configs)\n\nHopefully, after this patch I won\u0027t get any more compile broken\nemails. :-)\n\nv3:\n  changed a couple of \u0027linux/nmi.h\u0027 -\u003e \u0027asm/nmi.h\u0027 to pick-up correct function\n  prototypes when CONFIG_HARDLOCKUP_DETECTOR is not set.\n\nSigned-off-by: Don Zickus \u003cdzickus@redhat.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: fweisbec@gmail.com\nLKML-Reference: \u003c1293044403-14117-1-git-send-email-dzickus@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "radix-tree: fix RCU bug\n\nSalman Qazi describes the following radix-tree bug:\n\nIn the following case, we get can get a deadlock:\n\n0.  The radix tree contains two items, one has the index 0.\n1.  The reader (in this case find_get_pages) takes the rcu_read_lock.\n2.  The reader acquires slot(s) for item(s) including the index 0 item.\n3.  The non-zero index item is deleted, and as a consequence the other item is\n    moved to the root of the tree. The place where it used to be is queued for\n    deletion after the readers finish.\n3b. The zero item is deleted, removing it from the direct slot, it remains in\n    the rcu-delayed indirect node.\n4.  The reader looks at the index 0 slot, and finds that the page has 0 ref\n    count\n5.  The reader looks at it again, hoping that the item will either be freed or\n    the ref count will increase. This never happens, as the slot it is looking\n    at will never be updated. Also, this slot can never be reclaimed because\n    the reader is holding rcu_read_lock and is in an infinite loop.\n\nThe fix is to re-use the same \"indirect\" pointer case that requires a slot\nlookup retry into a general \"retry the lookup\" bit.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\nReported-by: Salman Qazi \u003csqazi@google.com\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

For cases where we can we can automatically prove that\nthe file offset is always ignored, we use noop_llseek, which maintains\nthe current behavior of not returning an error from a seek.\n\nNew drivers should normally not use noop_llseek but instead use no_llseek\nand call nonseekable_open at open time.  Existing drivers can be converted\nto do the same when the maintainer knows for certain that no user code\nrelies on calling seek on the device file.\n\nThe generated code is often incorrectly indented and right now contains\ncomments that clarify for each added line why a specific variant was\nchosen. In the version that gets submitted upstream, the comments will\nbe gone and I will manually fix the indentation, because there does not\nseem to be a way to do that using coccinelle.\n\nSome amount of

      "message": "modules: Fix module_bug_list list corruption race\n\nWith all the recent module loading cleanups, we\u0027ve minimized the code\nthat sits under module_mutex, fixing various deadlocks and making it\npossible to do most of the module loading in parallel.\n\nHowever, that whole conversion totally missed the rather obscure code\nthat adds a new module to the list for BUG() handling.  That code was\ndoubly obscure because (a) the code itself lives in lib/bugs.c (for\ndubious reasons) and (b) it gets called from the architecture-specific\n\"module_finalize()\" rather than from generic code.\n\nCalling it from arch-specific code makes no sense what-so-ever to begin\nwith, and is now actively wrong since that code isn\u0027t protected by the\nmodule loading lock any more.\n\nSo this commit moves the \"module_bug_{finalize,cleanup}()\" calls away\nfrom the arch-specific code, and into the generic code - and in the\nprocess protects it with the module_mutex so that the list operations\nare now safe.\n\nFuture fixups:\n - move the module list handling code into kernel/module.c where it\n   belongs.\n - get rid of \u0027module_bug_list\u0027 and just use the regular list of modules\n   (called \u0027modules\u0027 - imagine that) that we already create and maintain\n   for other reasons.\n\nReported-and-tested-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nCc: Adrian Bunk \u003cbunk@kernel.org\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: stable@kernel.org\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

The code walks down the tree\nsetting tags before it has fully resolved the path to the leaf under\nthe assumption there will be a leaf slot with the tag set in the\nrange it is searching.\n\nUnfortunately, this is not a valid assumption - we can abort after\nsetting a tag on an intermediate node if we overrun the number of\ntags we are allowed to set in a batch, or stop scanning because we\nwe have passed the last scan index before we reach a leaf slot with\nthe tag we are searching for set.\n\nAs a result, we can leave the function with tags set on intemediate\nnodes which can be tripped over later by tag-based lookups. The\nresult of these stale tags is that lookup may end prematurely or\nlivelock because the lookup cannot make progress.\n\nThe fix for the problem involves reocrding the traversal path we\ntake to the leaf nodes, and only propagating the tags back up the\ntree once the tag is set in the leaf node slot. We are already\nrecording the path for efficient traversal, so there is no\nadditional overhead to do the intermediately node tag setting in\nthis manner.\n\nThis fixes a radix tree lookup livelock triggered by the new\nwriteback sync livelock avoidance code introduced in commit\nf446daaea9d4a420d16c606f755f3689dcb2d0ce (\"mm: implement writeback\nlivelock avoidance using page tagging\").\n\nSigned-off-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nAcked-by: Jan Kara \u003cjack@suse.cz\u003e\n"

      "message": "rcu: Allow RCU CPU stall warnings to be off at boot, but manually enablable\n\nCurrently, if RCU CPU stall warnings are enabled, they are enabled\nimmediately upon boot.  They can be manually disabled via /sys (and\nalso re-enabled via /sys), and are automatically disabled upon panic.\nHowever, some users need RCU CPU stalls to be disabled at boot time,\nbut to be enabled without rebuilding/rebooting.  For example, someone\nrunning a real-time application in production might not want the\nadditional latency of RCU CPU stall detection in normal operation, but\nmight need to enable it at any point for fault isolation purposes.\n\nThis commit therefore provides a new CONFIG_RCU_CPU_STALL_DETECTOR_RUNNABLE\nkernel configuration parameter that maintains the current behavior\n(enable at boot) by default, but allows a kernel to be configured\nwith RCU CPU stall detection built into the kernel, but disabled at\nboot time.\n\nRequested-by: Clark Williams \u003cwilliams@redhat.com\u003e\nRequested-by: John Kacur \u003cjkacur@redhat.com\u003e\nSigned-off-by: Paul E.

Also when checking the active count, it is not\nactually necessary to increment it; this allows us to get rid of the read\nside undo code and simplify the calculation of the final rwsem count\nadjustment once we\u0027ve counted the reader threads to wake.\n\nThe basic observation is the following.  When there are waiter threads on\na rwsem and the spinlock is held, other threads can only increment the\nactive count by trying to grab the rwsem in down_xxxx().  However\ndown_xxxx() will notice there are waiter threads and take the down_failed\npath, blocking to acquire the spinlock on the way there.  Therefore, a\nthread observing an active count of zero with waiters queued and the\nspinlock held, is protected against other threads acquiring the rwsem\nuntil it wakes the last waiter or releases the spinlock.\n\nSigned-off-by: Michel Lespinasse \u003cwalken@google.com\u003e\nAcked-by: David Howells \u003cdhowells@redhat.com\u003e\nCc: Mike Waychison \u003cmikew@google.com\u003e\nCc: Suleiman Souhlal \u003csuleiman@google.com\u003e\nCc: Ying Han \u003cyinghan@google.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: \"H.
