2015-01-13ARM: dts: Only build dtb if associated Arch and/or SoC is enabledPeter Robinson1-73/+142
A number of arches (EXYNOS/IMX/TEGRA) are separated out into finer grained definitions whether it be sub ARCH or SOC definitions. The device tree blobs should only be built if the specific option is enabled that supports that device or it might be that there's an expectation that the device is supported when in actual fact it's not. This ensures only the relevant bits are built. Also standardised the line break between the arch/soc definitions and the dtbs to be on separate lines for better consistency as per feedback.

2015-01-11mm: fix corner case in anon_vma endless growing preventionKonstantin Khlebnikov1-2/+4
Fix for BUG_ON(anon_vma->degree) splashes in unlink_anon_vmas() ("kernel BUG at mm/rmap.c:399!") caused by commit 7a3ef208e662 ("mm: prevent endless growth of anon_vma hierarchy") Anon_vma_clone() is usually called for a copy of source vma in destination argument. If source vma has anon_vma it should be already in dst->anon_vma. NULL in dst->anon_vma is used as a sign that it's called from anon_vma_fork(). In this case anon_vma_clone() finds anon_vma for reusing. Vma_adjust() calls it differently and this breaks anon_vma reusing logic: anon_vma_clone() links vma to old anon_vma and updates degree counters but vma_adjust() overrides vma->anon_vma right after that. As a result final unlink_anon_vmas() decrements degree for wrong anon_vma. This patch assigns ->anon_vma before calling anon_vma_clone().

2015-01-11mm: Don't count the stack guard page towards RLIMIT_STACKLinus Torvalds1-2/+5
Commit fee7e49d4514 ("mm: propagate error from stack expansion even for guard page") made sure that we return the error properly for stack growth conditions. It also theorized that counting the guard page towards the stack limit might break something, but also said "Let's see if anybody notices". Somebody did notice. Apparently android-x86 sets the stack limit very close to the limit indeed, and including the guard page in the rlimit check causes the android 'zygote' process problems. So this adds the (fairly trivial) code to make the stack rlimit check be against the actual real stack size, rather than the size of the vma that includes the guard page.

This SoC belongs to the Armada 38x family. The main difference with the Armada 385 is that the 388 can handle two more SATA ports. Currently the consequence is the use of a different compatible string for the pinctrl node, in order to be able to use the pins associated to this 2 new SATA ports. The second SATA controller has also been moved from the armada38x.dtsi as it it specific to the Armada388 version. In the same time the Armada385 DB and Armada 385 RD board have been renamed in the 388 one and now include the armada-388.dtsi file.

2015-01-09sched/deadline: Avoid double-accounting in case of missed deadlinesLuca Abeni1-18/+1
The dl_runtime_exceeded() function is supposed to ckeck if a SCHED_DEADLINE task must be throttled, by checking if its current runtime is <= 0. However, it also checks if the scheduling deadline has been missed (the current time is larger than the current scheduling deadline), further decreasing the runtime if this happens. This "double accounting" is wrong: - In case of partitioned scheduling (or single CPU), this happens if task_tick_dl() has been called later than expected (due to small HZ values). In this case, the current runtime is also negative, and replenish_dl_entity() can take care of the deadline miss by recharging the current runtime to a value smaller than dl_runtime - In case of global scheduling on multiple CPUs, scheduling deadlines can be missed even if the task did not consume more runtime than expected, hence penalizing the task is wrong This patch fix this problem by throttling a SCHED_DEADLINE task only when its runtime becomes negative, and not modifying the runtime Signed-off-by: Luca Abeni <luca.abeni@unitn.it> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Acked-by: Juri Lelli <juri.lelli@gmail.com> Cc: <stable@vger.kernel.org> Cc: Dario Faggioli <raistlin@linux.it> Cc: Linus Torvalds <torvalds@linux-foundation.org> Link: http://lkml.kernel.org/r/1418813432-20797-3-git-send-email-luca.abeni@unitn.it Signed-off-by: Ingo Molnar <mingo@kernel.org>
2015-01-09sched/deadline: Fix migration of SCHED_DEADLINE tasksLuca Abeni1-3/+3
According to global EDF, tasks should be migrated between runqueues without checking if their scheduling deadlines and runtimes are valid. However, SCHED_DEADLINE currently performs such a check: a migration happens doing: deactivate_task(rq, next_task, 0); set_task_cpu(next_task, later_rq->cpu); activate_task(later_rq, next_task, 0); which ends up calling dequeue_task_dl(), setting the new CPU, and then calling enqueue_task_dl(). enqueue_task_dl() then calls enqueue_dl_entity(), which calls update_dl_entity(), which can modify scheduling deadline and runtime, breaking global EDF scheduling. As a result, some of the properties of global EDF are not respected: for example, a taskset {(30, 80), (40, 80), (120, 170)} scheduled on two cores can have unbounded response times for the third task even if 30/80+40/80+120/170 = 1.5809 < 2 This can be fixed by invoking update_dl_entity() only in case of wakeup, or if this is a new SCHED_DEADLINE task.

2015-01-09sched, fanotify: Deal with nested sleepsPeter Zijlstra1-5/+5
As per e23738a7300a ("sched, inotify: Deal with nested sleeps"). fanotify_read is a wait loop with sleeps in. Wait loops rely on task_struct::state and sleeps do too, since that's the only means of actually sleeping. Therefore the nested sleeps destroy the wait loop state and the wait loop breaks the sleep functions that assume TASK_RUNNING (mutex_lock). Fix this by using the new woken_wake_function and wait_woken() stuff, which registers wakeups in wait and thereby allows shrinking the task_state::state changes to the actual sleep part.
