This is particularly important\nfor architectures adding device tree support because the current\nimplementation (excluding PowerPC and SPARC) cannot handle\ntranslation for more than a single interrupt controller. irq_domain\nsupports device tree translation for any number of interrupt\ncontrollers.\n\nThis patch converts x86, Microblaze, ARM and MIPS to use irq_domain\nfor device tree irq translation. x86 is untested beyond compiling it,\nirq_domain is enabled for MIPS and Microblaze, but the old behaviour is\npreserved until the core code is modified to actually register an\nirq_domain yet. On ARM it works and is required for much of the new\nARM device tree board support.\n\nPowerPC has /not/ been converted to use this new infrastructure.

It will eventually\nupdate those bits ... in the struct page, but not in the PTE.\n\nAdditionally, it will not handle the lazy TLB flushing that can be\nrequired by some architectures in the fault case.\n\nBasically, gup is the wrong interface for the job. The patch provides a\nmore appropriate one which boils down to just calling handle_mm_fault()\nsince what we are trying to do is simulate a real page fault.\n\nThe futex code currently attempts to write to user memory within a\npagefault disabled section, and if that fails, tries to fix it up using\nget_user_pages().\n\nThis doesn\u0027t work on archs where the dirty and young bits are maintained\nby software, since they will gate access permission in the TLB, and will\nnot be updated by gup().\n\nIn addition, there\u0027s an expectation on some archs that a spurious write\nfault triggers a local TLB flush, and that is missing from the picture as\nwell.\n\nI decided that adding those \"features\" to gup() would be too much for this\nalready too complex function, and instead added a new simpler\nfixup_user_fault() which is essentially a wrapper around handle_mm_fault()\nwhich the futex code can call.\n\n[akpm@linux-foundation.org: coding-style

It has no effect\nunless sig_kernel_stop() \u003d\u003d T after the tracer resumes us, and in the\nlatter case the pending STOP_DEQUEUED means no SIGCONT in between, we\nshould stop.\n\nNote also that if SIGCONT was sent, PT_SEIZED tracee will correctly\nreport PTRACE_EVENT_STOP/SIGTRAP and thus the tracer can notice the fact\nSIGSTOP was cancelled.\n\nAlso, move the current-\u003eptrace check from ptrace_signal() to its caller,\nget_signal_to_deliver(), this looks more natural.\n\nSigned-off-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nAcked-by: Tejun Heo \u003ctj@kernel.org\u003e\n" }, { "commit": "40bcea7bbe8fe452a2d272e2ffd3dea281eec9ff", "tree": "aedb6d02e53e3cf84cc32fd81db84032cee205e1", "parents": [ "492f73a303b488ffd67097b2351d54aa6e6c7c73", "14a8fd7ceea6915c613746203d6e9a2bf273f16c" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Jul 21 09:32:40 2011 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Jul 21 09:32:40 2011 +0200" }, "message": "Merge branch \u0027tip/perf/core\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-2.6-trace into perf/core\n" }, { "commit": "492f73a303b488ffd67097b2351d54aa6e6c7c73", "tree": "6e6c16fbd628bb5eb577cfc70a488ca286563e58", "parents": [ "e08fbb78f03fe2c4f88824faf6f51ce6af185e11", "f7bc8b61f65726ff98f52e286b28e294499d7a08" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Jul 21 09:29:14 2011 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Jul 21 09:29:21 2011 +0200" }, "message": "Merge branch \u0027perf/urgent\u0027 into perf/core\n\nMerge reason: pick up the latest fixes - they won\u0027t make v3.0.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "11b80f459adaf91a712f95e7734a17655a36bf30", "tree": "b325ce2cb09cbe9e7d98879c71054621dbb97c3c", "parents": [ "bd5fe6c5eb9c548d7f07fe8f89a150bb6705e8e3" ], "author": { "name": "Christoph Hellwig", "email": "hch@infradead.org", "time": "Fri Jun 24 14:29:44 2011 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Wed Jul 20 20:47:47 2011 -0400" }, "message": "rw_semaphore: remove up/down_read_non_owner\n\nNow that the last users is gone these can be removed.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "cf6ace16a3cd8b728fb0afa68368fd40bbeae19f", "tree": "489c64380668e8c5a29d3f36f37554e4b081a647", "parents": [ "acc11eab70591744369722280c9ce162a6193494", "d1e9ae47a0285d3f1699e8219ce50f656243b93f" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jul 20 15:56:25 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jul 20 15:56:25 2011 -0700" }, "message": "Merge branch \u0027core-urgent-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027core-urgent-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n signal: align __lock_task_sighand() irq disabling and RCU\n softirq,rcu: Inform RCU of irq_exit() activity\n sched: Add irq_{enter,exit}() to scheduler_ipi()\n rcu: protect __rcu_read_unlock() against scheduler-using irq handlers\n rcu: Streamline code produced by __rcu_read_unlock()\n rcu: Fix RCU_BOOST race handling current-\u003ercu_read_unlock_special\n rcu: decrease rcu_report_exp_rnp coupling with scheduler\n" }, { "commit": "cbaa51524b3224813814607177a00c350ee35d12", "tree": "34f0fabff444e5dde2ee2b92d841abb97daf41b1", "parents": [ "3dcad5ff08f65ae30832220a0e0ee2eac3502a1a" ], "author": { "name": "John Stultz", "email": "john.stultz@linaro.org", "time": "Wed Jul 20 15:42:55 2011 -0700" }, "committer": { "name": "John Stultz", "email": "john.stultz@linaro.org", "time": "Wed Jul 20 15:42:55 2011 -0700" }, "message": "time: Fix stupid KERN_WARN compile issue\n\nTerribly embarassing.

This situation can cause\nthe instance of __rcu_read_unlock() invoked from interrupt to do some\nof the processing that would otherwise have been carried out by the\ntask-level instance of __rcu_read_unlock(). When the interrupt-level\ninstance of __rcu_read_unlock() is called with a scheduler lock held\nfrom interrupt-entry/exit situations where in_irq() returns false,\ndeadlock can result.\n\nThis commit resolves these deadlocks by using negative values of\nthe per-task -\u003ercu_read_lock_nesting counter to indicate that an\ninstance of __rcu_read_unlock() is in flight, which in turn prevents\ninstances from interrupt handlers from doing any special processing.\nThis patch is inspired by Steven Rostedt\u0027s earlier patch that similarly\nmade __rcu_read_unlock() guard against interrupt-mediated recursion\n(see https://lkml.org/lkml/2011/7/15/326), but this commit refines\nSteven\u0027s approach to avoid the need for preemption disabling on the\n__rcu_read_unlock() fastpath and to also avoid the need for manipulating\na separate per-CPU variable.\n\nThis patch avoids need for preempt_disable() by instead using negative\nvalues of the per-task -\u003ercu_read_lock_nesting counter. Note that nested\nrcu_read_lock()/rcu_read_unlock() pairs are still permitted, but they will\nnever see -\u003ercu_read_lock_nesting go to zero, and will therefore never\ninvoke rcu_read_unlock_special(), thus preventing them from seeing the\nRCU_READ_UNLOCK_BLOCKED bit should it be set in -\u003ercu_read_unlock_special.\nThis patch also adds a check for -\u003ercu_read_unlock_special being negative\nin rcu_check_callbacks(), thus preventing the RCU_READ_UNLOCK_NEED_QS\nbit from being set should a scheduling-clock interrupt occur while\n__rcu_read_unlock() is exiting from an outermost RCU read-side critical\nsection.\n\nOf course, __rcu_read_unlock() can be preempted during the time that\n-\u003ercu_read_lock_nesting is negative. This could result in the setting\nof the RCU_READ_UNLOCK_BLOCKED bit after __rcu_read_unlock() checks it,\nand would also result it this task being queued on the corresponding\nrcu_node structure\u0027s blkd_tasks list. Therefore, some later RCU read-side\ncritical section would enter rcu_read_unlock_special() to clean up --\nwhich could result in deadlock if that critical section happened to be in\nthe scheduler where the runqueue or priority-inheritance locks were held.\n\nThis situation is dealt with by making rcu_preempt_note_context_switch()\ncheck for negative -\u003ercu_read_lock_nesting, thus refraining from\nqueuing the task (and from setting RCU_READ_UNLOCK_BLOCKED) if we are\nalready exiting from the outermost RCU read-side critical section (in\nother words, we really are no longer actually in that RCU read-side\ncritical section). In addition, rcu_preempt_note_context_switch()\ninvokes rcu_read_unlock_special() to carry out the cleanup in this case,\nwhich clears out the -\u003ercu_read_unlock_special bits and dequeues the task\n(if necessary), in turn avoiding needless delay of the current RCU grace\nperiod and needless RCU priority boosting.\n\nIt is still illegal to call rcu_read_unlock() while holding a scheduler\nlock if the prior RCU read-side critical section has ever had either\npreemption or irqs enabled. However, the common use case is legal,\nnamely where then entire RCU read-side critical section executes with\nirqs disabled, for example, when the scheduler lock is held across the\nentire lifetime of the RCU read-side critical section.\n\nSigned-off-by: Paul E.

These deadlocks would result from RCU incorrectly\nbelieving that the just-ended RCU read-side critical section had been\npreempted and/or boosted. If that RCU read-side critical section was\nexecuted with either rq or pi locks held, RCU\u0027s ensuing (incorrect)\ncalls to the scheduler would cause the scheduler to attempt to once\nagain acquire the rq and pi locks, resulting in deadlock. More complex\ndeadlock cycles are also possible, involving multiple rq and pi locks\nas well as locks from multiple rcu_node structures.\n\nThis commit fixes synchronization by creating -\u003ercu_boosted field in\ntask_struct that is accessed and modified only when holding the -\u003elock\nin the rcu_node structure on which the task is queued (on that rcu_node\nstructure\u0027s -\u003eblkd_tasks list). This results in tasks accessing only\ntheir own current-\u003ercu_read_unlock_special fields, making unsynchronized\naccess once again legal, and keeping the rcu_read_unlock() fastpath free\nof atomic instructions and memory barriers.\n\nThe reason that the rcu_read_unlock() fastpath does not need to access\nthe new current-\u003ercu_boosted field is that this new field cannot\nbe non-zero unless the RCU_READ_UNLOCK_BLOCKED bit is set in the\ncurrent-\u003ercu_read_unlock_special field. Therefore, rcu_read_unlock()\nneed only test current-\u003ercu_read_unlock_special: if that is zero, then\ncurrent-\u003ercu_boosted must also be zero.\n\nThis bug does not affect TINY_PREEMPT_RCU because this implementation\nof RCU accesses current-\u003ercu_read_unlock_special with irqs disabled,\nthus preventing races on the !SMP systems that TINY_PREEMPT_RCU runs on.\n\nMaybe-reported-by: Dave Jones \u003cdavej@redhat.com\u003e\nMaybe-reported-by: Sergey Senozhatsky \u003csergey.senozhatsky@gmail.com\u003e\nReported-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nSigned-off-by: Paul E.

It may\nwant to wakeup the system after a predefined amount of time or at a\npredefined event decided while entering suspend for polling or delayed\nwork. Then, it may want to enter suspend again if its predefined wakeup\ncondition is the only wakeup reason and there is no outstanding events;\nthus, it does not wakeup the userspace unnecessary or unnecessary\ndevices and keeps suspended as long as possible (saving the power).\n\nEnabling a system to wakeup after a specified time can be easily\nachieved by using RTC. However, to enter suspend again immediately\nwithout invoking userland and unrelated devices, we need additional\nfeatures in the suspend framework.\n\nSuch need comes from:\n\n 1. Monitoring a critical device status without interrupts that can\nwakeup the system. (in-suspend polling)\n An example is ambient temperature monitoring that needs to shut down\nthe system or a specific device function if it is too hot or cold. The\ntemperature of a specific device may be needed to be monitored as well;\ne.g., a charger monitors battery temperature in order to stop charging\nif overheated.\n\n 2. Execute critical \"delayed work\" at suspend.\n A driver or a system/board may have a delayed work (or any similar\nthings) that it wants to execute at the requested time.\n For example, some chargers want to check the battery voltage some\ntime (e.g., 30 seconds) after the battery is fully charged and the\ncharger has stopped. Then, the charger restarts charging if the voltage\nhas dropped more than a threshold, which is smaller than \"restart-charger\"\nvoltage, which is a threshold to restart charging regardless of the\ntime passed.\n\nThis patch allows to add \"suspend_again\" callback at struct\nplatform_suspend_ops and let the \"suspend_again\" callback return true if\nthe system is required to enter suspend again after the current instance\nof wakeup. Device-wise suspend_again implemented at dev_pm_ops or\nsyscore is not done because: a) suspend_again feature is usually under\nplatform-wise decision and controls the behavior of the whole platform\nand b) There are very limited devices related to the usage cases of\nsuspend_again; chargers and temperature sensors are mentioned so far.\n\nWith suspend_again callback registered at struct platform_suspend_ops\nsuspend_ops in kernel/power/suspend.c with suspend_set_ops by the\nplatform, the suspend framework tries to enter suspend again by\nlooping suspend_enter() if suspend_again has returned true and there has\nbeen no errors in the suspending sequence or pending wakeups (by\npm_wakeup_pending).\n\nTested at Exynos4-NURI.\n\n[rjw: Fixed up kerneldoc comment for suspend_enter().]\n\nSigned-off-by: MyungJoo Ham \u003cmyungjoo.ham@samsung.com\u003e\nSigned-off-by: Kyungmin Park \u003ckyungmin.park@samsung.com\u003e\nAcked-by: Pavel Machek \u003cpavel@ucw.cz\u003e\nSigned-off-by: Rafael J.
