      "message": "stop_machine: implement stop_machine_from_inactive_cpu()\n\nCurrently, mtrr wants stop_machine functionality while a CPU is being\nbrought up.  As stop_machine() requires the calling CPU to be active,\nmtrr implements its own stop_machine using stop_one_cpu() on each\nonline CPU.  This doesn\u0027t only unnecessarily duplicate complex logic\nbut also introduces a possibility of deadlock when it races against\nthe generic stop_machine().\n\nThis patch implements stop_machine_from_inactive_cpu() to serve such\nuse cases.  Its functionality is basically the same as stop_machine();\nhowever, it should be called from a CPU which isn\u0027t active and doesn\u0027t\ndepend on working scheduling on the calling CPU.\n\nThis is achieved by using busy loops for synchronization and\nopen-coding stop_cpus queuing and waiting with direct invocation of\nfn() for local CPU inbetween.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nLink: http://lkml.kernel.org/r/20110623182056.982526827@sbsiddha-MOBL3.sc.intel.com\nSigned-off-by: Suresh Siddha \u003csuresh.b.siddha@intel.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: H.

The system seems\nto be hung at a point where migration_call() tries to kill the\nmigration_thread of the dying CPU, which just got moved to the current\nCPU. This migration thread does not get a chance to run (and die) since\nrt_throttled is set to 1 on current, and it doesn\u0027t get cleared as the\nhrtimer which is supposed to reset the rt bandwidth\n(sched_rt_period_timer) is tied to the CPU which we just marked dead!\n\nSolution: This patch pushes the killing of migration thread to\n\"CPU_POST_DEAD\" event.

      "message": "sched: replace migration_thread with cpu_stop\n\nCurrently migration_thread is serving three purposes - migration\npusher, context to execute active_load_balance() and forced context\nswitcher for expedited RCU synchronize_sched.  All three roles are\nhardcoded into migration_thread() and determining which job is\nscheduled is slightly messy.\n\nThis patch kills migration_thread and replaces all three uses with\ncpu_stop.  The three different roles of migration_thread() are\nsplitted into three separate cpu_stop callbacks -\nmigration_cpu_stop(), active_load_balance_cpu_stop() and\nsynchronize_sched_expedited_cpu_stop() - and each use case now simply\nasks cpu_stop to execute the callback as necessary.\n\nsynchronize_sched_expedited() was implemented with private\npreallocated resources and custom multi-cpu queueing and waiting\nlogic, both of which are provided by cpu_stop.\nsynchronize_sched_expedited_count is made atomic and all other shared\nresources along with the mutex are dropped.\n\nsynchronize_sched_expedited() also implemented a check to detect cases\nwhere not all the callback got executed on their assigned cpus and\nfall back to synchronize_sched().  If called with cpu hotplug blocked,\ncpu_stop already guarantees that and the condition cannot happen;\notherwise, stop_machine() would break.  However, this patch preserves\nthe paranoid check using a cpumask to record on which cpus the stopper\nran so that it can serve as a bisection point if something actually\ngoes wrong theree.\n\nBecause the internal execution state is no longer visible,\nrcu_expedited_torture_stats() is removed.\n\nThis patch also renames cpu_stop threads to from \"stopper/%d\" to\n\"migration/%d\".  The names of these threads ultimately don\u0027t matter\nand there\u0027s no reason to make unnecessary userland visible changes.\n\nWith this patch applied, stop_machine() and sched now share the same\nresources.  stop_machine() is faster without wasting any resources and\nsched migration users are much cleaner.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nAcked-by: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Dipankar Sarma \u003cdipankar@in.ibm.com\u003e\nCc: Josh Triplett \u003cjosh@freedesktop.org\u003e\nCc: Paul E.

These are patterned after the\n    node_to_cpumask_ptr macros.\n\n    In general terms, if there is a cpumask_of_cpu_map[] then a pointer to\n    the cpumask_of_cpu_map[cpu] entry is used.  The cpumask_of_cpu_map\n    is provided when there is a large NR_CPUS count, reducing\n    greatly the amount of code generated and stack space used for\n    cpumask_of_cpu().  The pointer to the cpumask_t value is needed for\n    calling set_cpus_allowed_ptr() to reduce the amount of stack space\n    needed to pass the cpumask_t value.\n\n    If there isn\u0027t a cpumask_of_cpu_map[], then a temporary variable is\n    declared and filled in with value from cpumask_of_cpu(cpu) as well as\n    a pointer variable pointing to this temporary variable.  Afterwards,\n    the pointer is used to reference the cpumask value.

I could also reproduce the problem on a 4 way z/VM host with\na 64 way guest.\n\nIt turned out that the guest was consuming all available cpus mostly for\nspinning on scheduler locks like rq-\u003elock. This is expected as the threads are\ncalling yield all the time.\nThe problem is now, that the host scheduling decisings together with the guest\nscheduling decisions and spinlocks not being fair managed to create an\ninteresting scenario similar to a live lock. (Sometimes the hang resolved\nitself after some minutes)\n\nChanging stop_machine to yield the cpu to the hypervisor when yielding inside\nthe guest fixed the problem for me. While I am not completely happy with this\npatch, I think it causes no harm and it really improves the situation for me.\n\nI used cpu_relax for yielding to the hypervisor, does that work on all\narchitectures?\n\np.s.: If you want to reproduce the problem, cpu hotplug and kprobes use\nstop_machine_run and both triggered the problem after some retries.\n\nSigned-off-by: Christian Borntraeger \u003cborntraeger@de.ibm.com\u003e\nCC: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\n"

      "message": "[PATCH] stop_machine() vs. synchronous IPI send deadlock\n\nThis fixes deadlock of stop_machine() vs.  synchronous IPI send.  The\nproblem is that stop_machine() disables interrupts before disabling\npreemption on other CPUs.  So if another CPU is preempted and then calls\nsomething like flush_tlb_all() it will deadlock with CPU doing\nstop_machine() and which can\u0027t process IPI due to disabled IRQs.\n\nI changed stop_machine() to do the same things exactly as it does on other\nCPUs, i.e.  it should disable preemption first on _all_ CPUs including\nitself and only after that disable IRQs.\n\nSigned-off-by: Kirill Korotaev \u003cdev@sw.ru\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nCc: \"Andrey Savochkin\" \u003csaw@sawoct.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

Replaces all existing\n   uses of _smp_processor_id() and __smp_processor_id(). Defined\n   by every SMP architecture in include/asm-*/smp.h.\n\nThere is one new internal symbol, dependent on DEBUG_PREEMPT:\n\n - debug_smp_processor_id(): internal debug variant, mapped to\n                             smp_processor_id().\n\nAlso, i moved debug_smp_processor_id() from lib/kernel_lock.c into a new\nlib/smp_processor_id.c file.  All related comments got updated and/or\nclarified.\n\nI have build/boot tested the following 8 .config combinations on x86:\n\n {SMP,UP} x {PREEMPT,!PREEMPT} x {DEBUG_PREEMPT,!DEBUG_PREEMPT}\n\nI have also build/boot tested x64 on UP/PREEMPT/DEBUG_PREEMPT.
