* sched: Remove member rt_se from struct rt_rqYong Zhang2010-02-04
| | | | | | | | | | | | It's a duplicate of tg->rt_se[cpu] and the only usage is sched_rt_rq_dequeue() and sched_rt_rq_enqueue(). After the first patch to those two function. rt_se can be removed.

| | | | | | | | | | | | This is the first step to remove rt_rq member rt_se because it have the same meaning with tg->rt_se[cpu]. And the latter style is also used by the fair scheduling class.

* sched: Queue a deboosted task to the head of the RT prio queueThomas Gleixner2010-01-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rtmutex_set_prio() is used to implement priority inheritance for futexes. When a task is deboosted it gets enqueued at the tail of its RT priority list. This is violating the POSIX scheduling semantics: rt priority list X contains two runnable tasks A and B task A runs with priority X and holds mutex M task C preempts A and is blocked on mutex M -> task A is boosted to priority of task C (Y) task A unlocks the mutex M and deboosts itself -> A is dequeued from rt priority list Y -> A is enqueued to the tail of rt priority list X task C schedules away task B runs This is wrong as task A did not schedule away and therefor violates the POSIX scheduling semantics. Enqueue the task to the head of the priority list instead.

| | | | | | | | | | | | | | | We want to update the sched_group_powers when balance_cpu == this_cpu.

* sched: Remove load_balance_newidle()Peter Zijlstra2010-01-21
| | | | | | | | | | | | | | | | | | The two functions: load_balance{,_newidle}() are very similar, with the following differences: - rq->lock usage - sb->balance_interval updates - *balance check So remove the load_balance_newidle() call with load_balance(.idle = CPU_NEWLY_IDLE), explicitly unlock the rq->lock before calling (would be done by double_lock_balance() anyway), and ignore the other differences for now.

* sched: Unify load_balance{,_newidle}()Peter Zijlstra2010-01-21
| | | | | | | | | | | | | | | | load_balance() and load_balance_newidle() look remarkably similar, one key point they differ in is the condition on when to active balance. So split out that logic into a separate function. One side effect is that previously load_balance_newidle() used to fail and return -1 under these conditions, whereas now it doesn't. I've not yet fully figured out the whole -1 return case for either load_balance{,_newidle}().

This way there is a guarantee the syslog won't be flooded for any sane program. The original attempt at this made the tables non const and stored the flag inline. Linus suggested using a separate hash table for this, this is based on a code snippet from him. The hash implies this is not exact and can sometimes not print a new sysctl due to a hash collision, but in practice this should not be a problem I used a FNV32 hash over the binary string with a 32byte bitmap. This gives relatively little collisions when all the predefined binary sysctls are hashed: size 256 bucket length number 0: [25] 1: [67] 2: [88] 3: [47] 4: [22] 5: [6] 6: [1] The worst case is a single collision of 6 hash values.

Also: - changed to platform_driver_probe() since the device is created right there with the driver; - added __devexit annotation to remove method; - fixed memory leak on module unload - named platform_device_del() is not enough to free platform device, need platform_device_unregister().

Moreover SN06 should be called with only the descriptor offset to make sure we hit the rfkill controlling function (F124 or F135) with a 0 argument to get a full list of features.
