      "message": "[PATCH] lockdep: core\n\nDo \u0027make oldconfig\u0027 and accept all the defaults for new config options -\nreboot into the kernel and if everything goes well it should boot up fine and\nyou should have /proc/lockdep and /proc/lockdep_stats files.\n\nTypically if the lock validator finds some problem it will print out\nvoluminous debug output that begins with \"BUG: ...\" and which syslog output\ncan be used by kernel developers to figure out the precise locking scenario.\n\nWhat does the lock validator do?  It \"observes\" and maps all locking rules as\nthey occur dynamically (as triggered by the kernel\u0027s natural use of spinlocks,\nrwlocks, mutexes and rwsems).  Whenever the lock validator subsystem detects a\nnew locking scenario, it validates this new rule against the existing set of\nrules.  If this new rule is consistent with the existing set of rules then the\nnew rule is added transparently and the kernel continues as normal.  If the\nnew rule could create a deadlock scenario then this condition is printed out.\n\nWhen determining validity of locking, all possible \"deadlock scenarios\" are\nconsidered: assuming arbitrary number of CPUs, arbitrary irq context and task\ncontext constellations, running arbitrary combinations of all the existing\nlocking scenarios.  In a typical system this means millions of separate\nscenarios.  This is why we call it a \"locking correctness\" validator - for all\nrules that are observed the lock validator proves it with mathematical\ncertainty that a deadlock could not occur (assuming that the lock validator\nimplementation itself is correct and its internal data structures are not\ncorrupted by some other kernel subsystem).  [see more details and conditionals\nof this statement in include/linux/lockdep.h and\nDocumentation/lockdep-design.txt]\n\nFurthermore, this \"all possible scenarios\" property of the validator also\nenables the finding of complex, highly unlikely multi-CPU multi-context races\nvia single single-context rules, increasing the likelyhood of finding bugs\ndrastically.  In practical terms: the lock validator already found a bug in\nthe upstream kernel that could only occur on systems with 3 or more CPUs, and\nwhich needed 3 very unlikely code sequences to occur at once on the 3 CPUs.\nThat bug was found and reported on a single-CPU system (!).  So in essence a\nrace will be found \"piecemail-wise\", triggering all the necessary components\nfor the race, without having to reproduce the race scenario itself!  In its\nshort existence the lock validator found and reported many bugs before they\nactually caused a real deadlock.\n\nTo further increase the efficiency of the validator, the mapping is not per\n\"lock instance\", but per \"lock-class\".  For example, all struct inode objects\nin the kernel have inode-\u003einotify_mutex.  If there are 10,000 inodes cached,\nthen there are 10,000 lock objects.  But -\u003einotify_mutex is a single \"lock\ntype\", and all locking activities that occur against -\u003einotify_mutex are\n\"unified\" into this single lock-class.  The advantage of the lock-class\napproach is that all historical -\u003einotify_mutex uses are mapped into a single\n(and as narrow as possible) set of locking rules - regardless of how many\ndifferent tasks or inode structures it took to build this set of rules.  The\nset of rules persist during the lifetime of the kernel.\n\nTo see the rough magnitude of checking that the lock validator does, here\u0027s a\nportion of /proc/lockdep_stats, fresh after bootup:\n\n lock-classes:                            694 [max: 2048]\n direct dependencies:                  1598 [max: 8192]\n indirect dependencies:               17896\n all direct dependencies:             16206\n dependency chains:                    1910 [max: 8192]\n in-hardirq chains:                      17\n in-softirq chains:                     105\n in-process chains:                    1065\n stack-trace entries:                 38761 [max: 131072]\n combined max dependencies:         2033928\n hardirq-safe locks:                     24\n hardirq-unsafe locks:                  176\n softirq-safe locks:                     53\n softirq-unsafe locks:                  137\n irq-safe locks:                         59\n irq-unsafe locks:                      176\n\nThe lock validator has observed 1598 actual single-thread locking patterns,\nand has validated all possible 2033928 distinct locking scenarios.\n\nMore details about the design of the lock validator can be found in\nDocumentation/lockdep-design.txt, which can also found at:\n\n   http://redhat.com/~mingo/lockdep-patches/lockdep-design.txt\n\n[bunk@stusta.de: cleanups]\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] genirq: rename desc-\u003ehandler to desc-\u003echip\n\nThis patch-queue improves the generic IRQ layer to be truly generic, by adding\nvarious abstractions and features to it, without impacting existing\nfunctionality.\n\nWhile the queue can be best described as \"fix and improve everything in the\ngeneric IRQ layer that we could think of\", and thus it consists of many\nsmaller features and lots of cleanups, the one feature that stands out most is\nthe new \u0027irq chip\u0027 abstraction.\n\nThe irq-chip abstraction is about describing and coding and IRQ controller\ndriver by mapping its raw hardware capabilities [and quirks, if needed] in a\nstraightforward way, without having to think about \"IRQ flow\"\n(level/edge/etc.) type of details.\n\nThis stands in contrast with the current \u0027irq-type\u0027 model of genirq\narchitectures, which \u0027mixes\u0027 raw hardware capabilities with \u0027flow\u0027 details.\nThe patchset supports both types of irq controller designs at once, and\nconverts i386 and x86_64 to the new irq-chip design.\n\nAs a bonus side-effect of the irq-chip approach, chained interrupt controllers\n(master/slave PIC constructs, etc.) are now supported by design as well.\n\nThe end result of this patchset intends to be simpler architecture-level code\nand more consolidation between architectures.\n\nWe reused many bits of code and many concepts from Russell King\u0027s ARM IRQ\nlayer, the merging of which was one of the motivations for this patchset.\n\nThis patch:\n\nrename desc-\u003ehandler to desc-\u003echip.\n\nOriginally i did not want to do this, because it\u0027s a big patch.  But having\nboth \"desc-\u003ehandler\", \"desc-\u003ehandle_irq\" and \"action-\u003ehandler\" caused a\nlarge degree of confusion and made the code appear alot less clean than it\ntruly is.\n\nI have also attempted a dual approach as well by introducing a\ndesc-\u003echip alias - but that just wasnt robust enough and broke\nfrequently.\n\nSo lets get over with this quickly.  The conversion was done automatically\nvia scripts and converts all the code in the kernel.\n\nThis renaming patch is the first one amongst the patches, so that the\nremaining patches can stay flexible and can be merged and split up\nwithout having some big monolithic patch act as a merge barrier.\n\n[akpm@osdl.org: build fix]\n[akpm@osdl.org: another build fix]\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

Each event registered by poll() triggers\nan interrupt.  So, for each free_irq() we must remove the corresponding\nhost fd from the table, which we do via this -release() method.\n\nIn this patch we add an appropriate hook for this, and remove all uses of\nit by pointing the hook to the said procedure; this is safe to do since the\nsaid procedure.\n\nAlso some cosmetic improvements are included.\n\nThis is heavily based on some work by Chris Wedgwood, which however didn\u0027t\nget the patch merged for something I\u0027d call a \"misunderstanding\" (the need\nfor this patch wasn\u0027t cleanly explained, thus adding the generic hook was\nfelt as undesirable).\n\nSigned-off-by: Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\nCC: Ingo Molnar \u003cmingo@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
