migration_call() will do all the things that update_runtime() does. So let's remove it. Furthermore, there is potential risk that the current code will catch BUG_ON at line 689 of rt.c when do cpu hotplug while there are realtime threads running because of enabling runtime twice while the rt_runtime may already changed.

In autogroup_create(), a tg is allocated and added to the task_groups list. If CONFIG_RT_GROUP_SCHED is set, this tg is then modified while on the list, without locking. This can race with someone walking the list, like __enable_runtime() during CPU unplug, and result in a use-after-free bug. To fix this, move sched_online_group(), which adds the tg to the list, to the end of the autogroup_create() function after the modification.

This large chunk of load calculation code can be easily divorced from the main core.c scheduler file, with only a couple prototypes and externs added to a kernel/sched header. Some recent commits expanded the code and the documentation of it, making it large enough to warrant separation. For example, see: 556061b0, "sched/nohz: Fix rq->cpu_load[] calculations" 5aaa0b7a, "sched/nohz: Fix rq->cpu_load calculations some more" 5167e8d5, "sched/nohz: Rewrite and fix load-avg computation -- again" More importantly, it helps reduce the size of the main sched/core.c by yet another significant amount (~600 lines).

Pull 'full dynticks' support from Ingo Molnar: "This tree from Frederic Weisbecker adds a new, (exciting! :-) core kernel feature to the timer and scheduler subsystems: 'full dynticks', or CONFIG_NO_HZ_FULL=y. This feature extends the nohz variable-size timer tick feature from idle to busy CPUs (running at most one task) as well, potentially reducing the number of timer interrupts significantly. This feature got motivated by real-time folks and the -rt tree, but the general utility and motivation of full-dynticks runs wider than that: - HPC workloads get faster: CPUs running a single task should be able to utilize a maximum amount of CPU power. A periodic timer tick at HZ=1000 can cause a constant overhead of up to 1.0%. This feature removes that overhead - and speeds up the system by 0.5%-1.0% on typical distro configs even on modern systems. - Real-time workload latency reduction: CPUs running critical tasks should experience as little jitter as possible. The last remaining source of kernel-related jitter was the periodic timer tick. - A single task executing on a CPU is a pretty common situation, especially with an increasing number of cores/CPUs, so this feature helps desktop and mobile workloads as well. The cost of the feature is mainly related to increased timer reprogramming overhead when a CPU switches its tick period, and thus slightly longer to-idle and from-idle latency. Configuration-wise a third mode of operation is added to the existing two NOHZ kconfig modes: - CONFIG_HZ_PERIODIC: [formerly !CONFIG_NO_HZ], now explicitly named as a config option. This is the traditional Linux periodic tick design: there's a HZ tick going on all the time, regardless of whether a CPU is idle or not. - CONFIG_NO_HZ_IDLE: [formerly CONFIG_NO_HZ=y], this turns off the periodic tick when a CPU enters idle mode. - CONFIG_NO_HZ_FULL: this new mode, in addition to turning off the tick when a CPU is idle, also slows the tick down to 1 Hz (one timer interrupt per second) when only a single task is running on a CPU. The .config behavior is compatible: existing !CONFIG_NO_HZ and CONFIG_NO_HZ=y settings get translated to the new values, without the user having to configure anything. CONFIG_NO_HZ_FULL is turned off by default. This feature is based on a lot of infrastructure work that has been steadily going upstream in the last 2-3 cycles: related RCU support and non-periodic cputime support in particular is upstream already. This tree adds the final pieces and activates the feature. The pull request is marked RFC because: - it's marked 64-bit only at the moment - the 32-bit support patch is small but did not get ready in time. - it has a number of fresh commits that came in after the merge window. The overwhelming majority of commits are from before the merge window, but still some aspects of the tree are fresh and so I marked it RFC. - it's a pretty wide-reaching feature with lots of effects - and while the components have been in testing for some time, the full combination is still not very widely used. That it's default-off should reduce its regression abilities and obviously there are no known regressions with CONFIG_NO_HZ_FULL=y enabled either. - the feature is not completely idempotent: there is no 100% equivalent replacement for a periodic scheduler/timer tick. In particular there's ongoing work to map out and reduce its effects on scheduler load-balancing and statistics. This should not impact correctness though, there are no known regressions related to this feature at this point. - it's a pretty ambitious feature that with time will likely be enabled by most Linux distros, and we'd like you to make input on its design/implementation, if you dislike some aspect we missed. Without flaming us to crisp! :-) Future plans: - there's ongoing work to reduce 1Hz to 0Hz, to essentially shut off the periodic tick altogether when there's a single busy task on a CPU. We'd first like 1 Hz to be exposed more widely before we go for the 0 Hz target though. - once we reach 0 Hz we can remove the periodic tick assumption from nr_running>=2 as well, by essentially interrupting busy tasks only as frequently as the sched_latency constraints require us to do - once every 4-40 msecs, depending on nr_running. I am personally leaning towards biting the bullet and doing this in v3.10, like the -rt tree this effort has been going on for too long - but the final word is up to you as usual.

Pull single_open() leak fixes from Al Viro: "A bunch of fixes for a moderately common class of bugs: file with single_open() done by its ->open() and seq_release as its ->release(). That leaks; fortunately, it's not _too_ common (either people manage to RTFM that says "When using single_open(), the programmer should use single_release() instead of seq_release() in the file_operations structure to avoid a memory leak", or they just copy a correct instance), but grepping through the tree has caught quite a pile. All of that is, AFAICS, -stable fodder, for as far as the patches apply.

Merge ipc fixes and cleanups from my IPC branch. The ipc locking has always been pretty ugly, and the scalability fixes to some degree made it even less readable. We had two cases of double unlocks in error paths due to this (one rcu read unlock, one semaphore unlock), and this fixes the bugs I found while trying to clean things up a bit so that we are less likely to have more. * ipc-cleanups: ipc: simplify rcu_read_lock() in semctl_nolock() ipc: simplify semtimedop/semctl_main() common error path handling ipc: move sem_obtain_lock() rcu locking into the only caller ipc: fix double sem unlock in semctl error path ipc: move the rcu_read_lock() from sem_lock_and_putref() into callers ipc: sem_putref() does not need the semaphore lock any more ipc: move rcu_read_unlock() out of sem_unlock() and into callers

This is needed because when scan_of_devices finds the GAISLER_GPTIMER core that corresponds to the SMP "ticker" timer, the previously set proper irq flow handler gets overwritten with an incorrect one.

With various straight RCU lock/unlock movements, one common exit path pattern had become rcu_read_unlock(); goto out_wakeup; and in fact there were no cases where we wanted to exit to out_wakeup _without_ releasing the RCU read lock. So replace that pattern with "goto out_rcu_wakeup", and remove the old out_wakeup.

sem_obtain_lock() was another of those functions that returned with the RCU lock held for reading in the success case. Move the RCU locking to the caller (semtimedop()), making it more obvious. We already did RCU locking elsewhere in that function. Side note: why does semtimedop() re-do the semphore lookup after the sleep, rather than just getting a reference to the semaphore it already looked up originally?

This is another ipc semaphore locking cleanup, trying to make the locking more straightforward. We move the rcu read locking into the callers of sem_lock_and_putref(), which in general means that we now mostly do the rcu_read_lock() and rcu_read_unlock() in the same function. Mostly. We still have the ipc_addid/newary/freeary mess, and things like ipcctl_pre_down_nolock().
