      "message": "hrtimers: allow the hot-unplugging of all cpus\n\nImpact: fix CPU hotplug hang on Power6 testbox\n\nOn architectures that support offlining all cpus (at least powerpc/pseries),\nhot-unpluging the tick_do_timer_cpu can result in a system hang.\n\nThis comes from the fact that if the cpu going down happens to be the\ncpu doing the tick, then as the tick_do_timer_cpu handover happens after the\ncpu is dead (via the CPU_DEAD notification), we\u0027re left without ticks,\njiffies are frozen and any task relying on timers (msleep, ...) is stuck.\nThat\u0027s particularly the case for the cpu looping in __cpu_die() waiting\nfor the dying cpu to be dead.\n\nThis patch addresses this by having the tick_do_timer_cpu handover happen\nearlier during the CPU_DYING notification. For this, a new clockevent\nnotification type is introduced (CLOCK_EVT_NOTIFY_CPU_DYING) which is triggered\nin hrtimer_cpu_notify().\n\nSigned-off-by: Sebastien Dugue \u003csebastien.dugue@bull.net\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "hrtimers: increase clock min delta threshold while interrupt hanging\n\nImpact: avoid timer IRQ hanging slow systems\n\nWhile using the function graph tracer on a virtualized system, the\nhrtimer_interrupt can hang the system on an infinite loop.\n\nThis can be caused in several situations:\n\n - the hardware is very slow and HZ is set too high\n\n - something intrusive is slowing the system down (tracing under emulation)\n\n... and the next clock events to program are always before the current time.\n\nThis patch implements a reasonable compromise: if such a situation is\ndetected, we share the CPUs time in 1/4 to process the hrtimer interrupts.\nThis is enough to let the system running without serious starvation.\n\nIt has been successfully tested under VirtualBox with 1000 HZ and 100 HZ\nwith function graph tracer launched. On both cases, the clock events were\nincreased until about 25 ms periodic ticks, which means 40 HZ.\n\nSo we change a hard to debug hang into a warning message and a system that\nstill manages to limp along.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

If this timer is a\nperiodic timer (which should use hrtimer_forward() to advance its time)\nthen it might be possible to end up in an inf. recursive loop due to the\nfact that hrtimer_forward() doesn\u0027t round up to the next timer\ngranularity, and therefore keeps on calling the callback - obviously\nthis needs a fix.\n\nAside from that, this seems to compile and actually boot on my dual core\ntest box - although I\u0027m sure there are some bugs in, me not hitting any\nmakes me certain :-)\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "hrtimer: prevent migration for raising softirq\n\nDue to a possible deadlock, the waking of the softirq was pushed outside\nof the hrtimer base locks. See commit 0c96c5979a522c3323c30a078a70120e29b5bdbc\n\nUnfortunately this allows the task to migrate after setting up the softirq\nand raising it. Since softirqs run a queue that is per-cpu we may raise the\nsoftirq on the wrong CPU and this will keep the queued softirq task from\nrunning.\n\nTo solve this issue, this patch disables preemption around the releasing\nof the hrtimer lock and raising of the softirq.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
