Previously the cpu migration counts reported by perf\nstat were bogus, ranging from negative to several thousand for\na single \"lat_ctx 2 8 32\" run.  With this patch the cpu\nmigration count reported for \"lat_ctx 2 8 32\" is almost always\nbetween 35 and 44.\n\nThis fixes the problem by adding a call into the perf_counter\ncode from set_task_cpu when tasks are migrated.  This enables\nus to use the generic swcounter code (with some modifications)\nfor the cpu migration counter.\n\nThis modifies the swcounter code to allow a NULL regs pointer\nto be passed in to perf_swcounter_ctx_event() etc.  The cpu\nmigration counter does this because there isn\u0027t necessarily a\npt_regs struct for the task available.  In this case, the\ncounter will not have interrupt capability - but the migration\ncounter didn\u0027t have interrupt capability before, so this is no\nloss.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Corey Ashford \u003ccjashfor@linux.vnet.ibm.com\u003e\nCc: Marcelo Tosatti \u003cmtosatti@redhat.com\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: John Kacur \u003cjkacur@redhat.com\u003e\nLKML-Reference: \u003c18979.35006.819769.416327@cargo.ozlabs.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "perf_counter: Provide functions for locking and pinning the context for a task\n\nThis abstracts out the code for locking the context associated\nwith a task.  Because the context might get transferred from\none task to another concurrently, we have to check after\nlocking the context that it is still the right context for the\ntask and retry if not.  This was open-coded in\nfind_get_context() and perf_counter_init_task().\n\nThis adds a further function for pinning the context for a\ntask, i.e. marking it so it can\u0027t be transferred to another\ntask.  This adds a \u0027pin_count\u0027 field to struct\nperf_counter_context to indicate that a context is pinned,\ninstead of the previous method of setting the parent_gen count\nto all 1s.  Pinning the context with a pin_count is easier to\nundo and doesn\u0027t require saving the parent_gen value.  This\nalso adds a perf_unpin_context() to undo the effect of\nperf_pin_task_context() and changes perf_counter_init_task to\nuse it.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Corey Ashford \u003ccjashfor@linux.vnet.ibm.com\u003e\nCc: Marcelo Tosatti \u003cmtosatti@redhat.com\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: John Kacur \u003cjkacur@redhat.com\u003e\nLKML-Reference: \u003c18979.34748.755674.596386@cargo.ozlabs.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "perf_counter: Fix race in attaching counters to tasks and exiting\n\nCommit 564c2b21 (\"perf_counter: Optimize context switch between\nidentical inherited contexts\") introduced a race where it is possible\nthat a counter being attached to a task could get attached to the\nwrong task, if the task is one that has inherited its context from\nanother task via fork.  This happens because the optimized context\nswitch could switch the context to another task after find_get_context\nhas read task-\u003eperf_counter_ctxp.  In fact, it\u0027s possible that the\ncontext could then get freed, if the other task then exits.\n\nThis fixes the problem by protecting both the context switch and the\ncritical code in find_get_context with spinlocks.  The context switch\nlocks the cxt-\u003elock of both the outgoing and incoming contexts before\nswapping them.  That means that once code such as find_get_context\nhas obtained the spinlock for the context associated with a task,\nthe context can\u0027t get swapped to another task.  However, the context\nmay have been swapped in the interval between reading\ntask-\u003eperf_counter_ctxp and getting the lock, so it is necessary to\ncheck and retry.\n\nTo make sure that none of the contexts being looked at in\nfind_get_context can get freed, this changes the context freeing code\nto use RCU.  Thus an rcu_read_lock() is sufficient to ensure that no\ncontexts can get freed.  This part of the patch is lifted from a patch\nposted by Peter Zijlstra.\n\nThis also adds a check to make sure that we can\u0027t add a counter to a\ntask that is exiting.\n\nThere is also a race between perf_counter_exit_task and\nfind_get_context; this solves the race by moving the get_ctx that\nwas in perf_counter_alloc into the locked region in find_get_context,\nso that once find_get_context has got the context for a task, it\nwon\u0027t get freed even if the task calls perf_counter_exit_task.  It\ndoesn\u0027t matter if new top-level (non-inherited) counters get attached\nto the context after perf_counter_exit_task has detached the context\nfrom the task.  They will just stay there and never get scheduled in\nuntil the counters\u0027 fds get closed, and then perf_release will remove\nthem from the context and eventually free the context.\n\nWith this, we are now doing the unclone in find_get_context rather\nthan when a counter was added to or removed from a context (actually,\nwe were missing the unclone_ctx() call when adding a counter to a\ncontext).  We don\u0027t need to unclone when removing a counter from a\ncontext because we have no way to remove a counter from a cloned\ncontext.\n\nThis also takes out the smp_wmb() in find_get_context, which Peter\nZijlstra pointed out was unnecessary because the cmpxchg implies a\nfull barrier anyway.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Corey Ashford \u003ccjashfor@linux.vnet.ibm.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Marcelo Tosatti \u003cmtosatti@redhat.com\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: John Kacur \u003cjkacur@redhat.com\u003e\nLKML-Reference: \u003c18974.33033.667187.273886@cargo.ozlabs.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "perf_counter: Optimize context switch between identical inherited contexts\n\nWhen monitoring a process and its descendants with a set of inherited\ncounters, we can often get the situation in a context switch where\nboth the old (outgoing) and new (incoming) process have the same set\nof counters, and their values are ultimately going to be added together.\nIn that situation it doesn\u0027t matter which set of counters are used to\ncount the activity for the new process, so there is really no need to\ngo through the process of reading the hardware counters and updating\nthe old task\u0027s counters and then setting up the PMU for the new task.\n\nThis optimizes the context switch in this situation.  Instead of\nscheduling out the perf_counter_context for the old task and\nscheduling in the new context, we simply transfer the old context\nto the new task and keep using it without interruption.  The new\ncontext gets transferred to the old task.  This means that both\ntasks still have a valid perf_counter_context, so no special case\nis introduced when the old task gets scheduled in again, either on\nthis CPU or another CPU.\n\nThe equivalence of contexts is detected by keeping a pointer in\neach cloned context pointing to the context it was cloned from.\nTo cope with the situation where a context is changed by adding\nor removing counters after it has been cloned, we also keep a\ngeneration number on each context which is incremented every time\na context is changed.  When a context is cloned we take a copy\nof the parent\u0027s generation number, and two cloned contexts are\nequivalent only if they have the same parent and the same\ngeneration number.  In order that the parent context pointer\nremains valid (and is not reused), we increment the parent\ncontext\u0027s reference count for each context cloned from it.\n\nSince we don\u0027t have individual fds for the counters in a cloned\ncontext, the only thing that can make two clones of a given parent\ndifferent after they have been cloned is enabling or disabling all\ncounters with prctl.  To account for this, we keep a count of the\nnumber of enabled counters in each context.  Two contexts must have\nthe same number of enabled counters to be considered equivalent.\n\nHere are some measurements of the context switch time as measured with\nthe lat_ctx benchmark from lmbench, comparing the times obtained with\nand without this patch series:\n\n\t\t-----Unmodified-----\t\tWith this patch series\nCounters:\tnone\t2 HW\t4H+4S\tnone\t2 HW\t4H+4S\n\n2 processes:\nAverage\t\t3.44\t6.45\t11.24\t3.12\t3.39\t3.60\nSt dev\t\t0.04\t0.04\t0.13\t0.05\t0.17\t0.19\n\n8 processes:\nAverage\t\t6.45\t8.79\t14.00\t5.57\t6.23\t7.57\nSt dev\t\t1.27\t1.04\t0.88\t1.42\t1.46\t1.42\n\n32 processes:\nAverage\t\t5.56\t8.43\t13.78\t5.28\t5.55\t7.15\nSt dev\t\t0.41\t0.47\t0.53\t0.54\t0.57\t0.81\n\nThe numbers are the mean and standard deviation of 20 runs of\nlat_ctx.

      "message": "perf_counter: Dynamically allocate tasks\u0027 perf_counter_context struct\n\nThis replaces the struct perf_counter_context in the task_struct with\na pointer to a dynamically allocated perf_counter_context struct.  The\nmain reason for doing is this is to allow us to transfer a\nperf_counter_context from one task to another when we do lazy PMU\nswitching in a later patch.\n\nThis has a few side-benefits: the task_struct becomes a little smaller,\nwe save some memory because only tasks that have perf_counters attached\nget a perf_counter_context allocated for them, and we can remove the\ninclusion of \u003clinux/perf_counter.h\u003e in sched.h, meaning that we don\u0027t\nend up recompiling nearly everything whenever perf_counter.h changes.\n\nThe perf_counter_context structures are reference-counted and freed\nwhen the last reference is dropped.  A context can have references\nfrom its task and the counters on its task.  Counters can outlive the\ntask so it is possible that a context will be freed well after its\ntask has exited.\n\nContexts are allocated on fork if the parent had a context, or\notherwise the first time that a per-task counter is created on a task.\nIn the latter case, we set the context pointer in the task struct\nlocklessly using an atomic compare-and-exchange operation in case we\nraced with some other task in creating a context for the subject task.\n\nThis also removes the task pointer from the perf_counter struct.  The\ntask pointer was not used anywhere and would make it harder to move a\ncontext from one task to another.  Anything that needed to know which\ntask a counter was attached to was already using counter-\u003ectx-\u003etask.\n\nThe __perf_counter_init_context function moves up in perf_counter.c\nso that it can be called from find_get_context, and now initializes\nthe refcount, but is otherwise unchanged.\n\nWe were potentially calling list_del_counter twice: once from\n__perf_counter_exit_task when the task exits and once from\n__perf_counter_remove_from_context when the counter\u0027s fd gets closed.\nThis adds a check in list_del_counter so it doesn\u0027t do anything if\nthe counter has already been removed from the lists.\n\nSince perf_counter_task_sched_in doesn\u0027t do anything if the task doesn\u0027t\nhave a context, and leaves cpuctx-\u003etask_ctx \u003d NULL, this adds code to\n__perf_install_in_context to set cpuctx-\u003etask_ctx if necessary, i.e. in\nthe case where the current task adds the first counter to itself and\nthus creates a context for itself.\n\nThis also adds similar code to __perf_counter_enable to handle a\nsimilar situation which can arise when the counters have been disabled\nusing prctl; that also leaves cpuctx-\u003etask_ctx \u003d NULL.\n\n[ Impact: refactor counter context management to prepare for new feature ]\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Corey Ashford \u003ccjashfor@linux.vnet.ibm.com\u003e\nCc: Marcelo Tosatti \u003cmtosatti@redhat.com\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nLKML-Reference: \u003c18966.10075.781053.231153@cargo.ozlabs.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "[ARM] Double check memmap is actually valid with a memmap has unexpected holes V2\n\npfn_valid() is meant to be able to tell if a given PFN has valid memmap\nassociated with it or not. In FLATMEM, it is expected that holes always\nhave valid memmap as long as there is valid PFNs either side of the hole.\nIn SPARSEMEM, it is assumed that a valid section has a memmap for the\nentire section.\n\nHowever, ARM and maybe other embedded architectures in the future free\nmemmap backing holes to save memory on the assumption the memmap is never\nused. The page_zone linkages are then broken even though pfn_valid()\nreturns true. A walker of the full memmap must then do this additional\ncheck to ensure the memmap they are looking at is sane by making sure the\nzone and PFN linkages are still valid. This is expensive, but walkers of\nthe full memmap are extremely rare.\n\nThis was caught before for FLATMEM and hacked around but it hits again for\nSPARSEMEM because the page_zone linkages can look ok where the PFN linkages\nare totally screwed. This looks like a hatchet job but the reality is that\nany clean solution would end up consumning all the memory saved by punching\nthese unexpected holes in the memmap. For example, we tried marking the\nmemmap within the section invalid but the section size exceeds the size of\nthe hole in most cases so pfn_valid() starts returning false where valid\nmemmap exists. Shrinking the size of the section would increase memory\nconsumption offsetting the gains.\n\nThis patch identifies when an architecture is punching unexpected holes\nin the memmap that the memory model cannot automatically detect and sets\nARCH_HAS_HOLES_MEMORYMODEL. At the moment, this is restricted to EP93xx\nwhich is the model sub-architecture this has been reported on but may expand\nlater. When set, walkers of the full memmap must call memmap_valid_within()\nfor each PFN and passing in what it expects the page and zone to be for\nthat PFN. If it finds the linkages to be broken, it assumes the memmap is\ninvalid for that PFN.\n\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\n"

      "message": "perf_counter: allow arch to supply event misc flags and instruction pointer\n\nAt present the values we put in overflow events for the misc\nflags indicating processor mode and the instruction pointer are\nobtained using the standard user_mode() and\ninstruction_pointer() functions. Those functions tell you where\nthe performance monitor interrupt was taken, which might not be\nexactly where the counter overflow occurred, for example\nbecause interrupts were disabled at the point where the\noverflow occurred, or because the processor had many\ninstructions in flight and chose to complete some more\ninstructions beyond the one that caused the counter overflow.\n\nSome architectures (e.g. powerpc) can supply more precise\ninformation about where the counter overflow occurred and the\nprocessor mode at that point.  This introduces new functions,\nperf_misc_flags() and perf_instruction_pointer(), which arch\ncode can override to provide more precise information if\navailable.  They have default implementations which are\nidentical to the existing code.\n\nThis also adds a new misc flag value,\nPERF_EVENT_MISC_HYPERVISOR, for the case where a counter\noverflow occurred in the hypervisor.  We encode the processor\nmode in the 2 bits previously used to indicate user or kernel\nmode; the values for user and kernel mode are unchanged and\nhypervisor mode is indicated by both bits being set.\n\n[ Impact: generalize perfcounter core facilities ]\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Corey Ashford \u003ccjashfor@linux.vnet.ibm.com\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nLKML-Reference: \u003c18956.1272.818511.561835@cargo.ozlabs.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

Now all platform_driver is registered by platform_driver_register,\n\t   which makes probe()/release()/... of platform_driver passed parameter\n\t   of platform_device *, so platform driver can get platform_data from\n\t   platform_device;\n\n\t2. Other kind of devices do not need to use platform_data, we can\n\t   decrease size of device if moving it to platform_device.\n\n\tTaking into consideration of thousands of files to be fixed and they\n\tcan\u0027t be finished in one night(maybe it will take a long time), so we\n\tkeep platform_data in device to allow two kind of cases coexist until\n\tall platform devices pass its platfrom data from\n\tplatform_device-\u003eplatform_data.\n\n\tAll patches to do this kind of conversion are welcome.\n\nAs we don\u0027t really want to do it, it was a bad idea.\n\nCc: David Brownell \u003cdavid-b@pacbell.net\u003e\nCc: Ming Lei \u003ctom.leiming@gmail.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n\n"

That happens because aout binary\nhandler gets on the top of the binfmt list due to late registration, and\nkernel attempts to execute the binary without preparatory work that must\nbe done by binfmt_loader.\n\nFixed by changing the registration order of the default binfmt handlers\nusing list_add_tail() and introducing insert_binfmt() function which\nplaces new handler on the top of the binfmt list.  This might be generally\nuseful for installing arch-specific frontends for default handlers or just\nfor overriding them.\n\nSigned-off-by: Ivan Kokshaysky \u003cink@jurassic.park.msu.ru\u003e\nCc: Al Viro \u003cviro@ZenIV.linux.org.uk\u003e\nCc: Richard Henderson \u003crth@twiddle.net\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
