2011-12-21sched: Fix cgroup movement of waking processDaisuke Nishimura
There is a small race between try_to_wake_up() and sched_move_task(), which is trying to move the process being woken up. try_to_wake_up() on CPU0 sched_move_task() on CPU1 --------------------------------+--------------------------------- raw_spin_lock_irqsave(p->pi_lock) task_waking_fair() ->p.se.vruntime -= cfs_rq->min_vruntime ttwu_queue() ->send reschedule IPI to CPU1 raw_spin_unlock_irqsave(p->pi_lock) task_rq_lock() -> tring to aquire both p->pi_lock and rq->lock with IRQ disabled task_move_group_fair() -> p.se.vruntime -= (old)cfs_rq->min_vruntime += (new)cfs_rq->min_vruntime task_rq_unlock() (via IPI) sched_ttwu_pending() raw_spin_lock(rq->lock) ttwu_do_activate() ... enqueue_entity() child.se->vruntime += cfs_rq->min_vruntime raw_spin_unlock(rq->lock) As a result, vruntime of the process becomes far bigger than min_vruntime, if (new)cfs_rq->min_vruntime >> (old)cfs_rq->min_vruntime. This patch fixes this problem by just ignoring such process in task_move_group_fair(), because the vruntime has already been normalized in task_waking_fair().

2011-12-21sched: Remove cfs bandwidth period check in tg_set_cfs_period()Kamalesh Babulal
Remove cfs bandwidth period check from tg_set_cfs_period. Invalid bandwidth period's lower/upper limits are denoted by min_cfs_quota_period/max_cfs_quota_period repsectively, and are checked against valid period in tg_set_cfs_bandwidth(). As pjt pointed out, negative input will result in very large unsigned numbers and will be caught by the max allowed period test.

2011-12-21sched: Fix load-balance lock-breakingPeter Zijlstra
The current lock break relies on contention on the rq locks, something which might never come because we've got IRQs disabled. Or will be very likely because on anything with more than 2 cpus a synchronized load-balance pass will very likely cause contention on the rq locks. Also the sched_nr_migrate thing fails when it gets trapped the loops of either the cgroup muck in load_balance_fair() or the move_tasks() load condition. Instead, use the new lb_flags field to propagate break/abort conditions for all these loops and create a new loop outside the irq disabled on the break being required.

2011-12-21perf events: Add PERF_COUNT_HW_REF_CPU_CYCLES generic PMU eventStephane Eranian
This event counts the number of reference core cpu cycles. Reference means that the event increments at a constant rate which is not subject to core CPU frequency adjustments. The event may not count when the processor is in halted (low power) state. As such, it may not be equivalent to wall clock time. However, when the processor is not halted state, the event keeps a constant correlation with wall clock time.

2011-12-21x86: Simplify code by removing a !SMP #ifdefs from 'struct cpuinfo_x86'Kevin Winchester
Several fields in struct cpuinfo_x86 were not defined for the !SMP case, likely to save space. However, those fields still have some meaning for UP, and keeping them allows some #ifdef removal from other files. The additional size of the UP kernel from this change is not significant enough to worry about keeping up the distinction: text data bss dec hex filename 4737168 506459 972040 6215667 5ed7f3 vmlinux.o.before 4737444 506459 972040 6215943 5ed907 vmlinux.o.after for a difference of 276 bytes for an example UP config. If someone wants those 276 bytes back badly then it should be implemented in a cleaner way.

Moreover, with the recent move of RX/TX to workqueues per device the global hci_task_lock was causing starvation between different HCI devices.

2011-12-20wl12xx: mark no sched scan only after FW eventEyal Shapira
stop sched scan isn't an immediate operation and we need to wait for PERIODIC_SCAN_COMPLETE_EVENT_ID after sending a stop before changing internal state and notifying upper layers. Not doing this caused problems when canceling an existing sched scan and immediately requesting to start a new one with a different configuration as the FW was still in the middle of the previous sched scan.
