+Subject: [PATCH] lockdep: Handle statically initialized PER_CPU locks proper
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.9/older/patches-4.9.13-rt10.tar.xz
+
+If a PER_CPU struct which contains a spin_lock is statically initialized
+via:
+
+DEFINE_PER_CPU(struct foo, bla) = {
+ .lock = __SPIN_LOCK_UNLOCKED(bla.lock)
+};
+
+then lockdep assigns a seperate key to each lock because the logic for
+assigning a key to statically initialized locks is to use the address as
+the key. With per CPU locks the address is obvioulsy different on each CPU.
+
+That's wrong, because all locks should have the same key.
+
+To solve this the following modifications are required:
+
+ 1) Extend the is_kernel/module_percpu_addr() functions to hand back the
+ canonical address of the per CPU address, i.e. the per CPU address
+ minus the per CPU offset.
+
+ 2) Check the lock address with these functions and if the per CPU check
+ matches use the returned canonical address as the lock key, so all per
+ CPU locks have the same key.
+
+ 3) Move the static_obj(key) check into look_up_lock_class() so this check
+ can be avoided for statically initialized per CPU locks. That's
+ required because the canonical address fails the static_obj(key) check
+ for obvious reasons.

The plain spinlock while sufficient does not update the local_lock

Alex Goins reported that mutex_destroy() on RT will force a GPL only symbol
which won't link and therefore fail on a non-GPL kernel module.
This does not happen on !RT and is a regression on RT which we would like to
avoid.
I try here the easy thing and to not use rt_mutex_destroy() if
-CONFIG_DEBUG_MUTEXES is not enabled. This will still break for the DEBUG
-configs so instead of adding a wrapper around rt_mutex_destroy() (which we have

+Subject: [PATCH] sched/rt: Add a missing rescheduling point
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.9/older/patches-4.9.13-rt10.tar.xz
+
+Since the change in commit:
+
+ fd7a4bed1835 ("sched, rt: Convert switched_{from, to}_rt() / prio_changed_rt() to balance callbacks")
+
+... we don't reschedule a task under certain circumstances:
+
+Lets say task-A, SCHED_OTHER, is running on CPU0 (and it may run only on
+CPU0) and holds a PI lock. This task is removed from the CPU because it
+used up its time slice and another SCHED_OTHER task is running. Task-B on
+CPU1 runs at RT priority and asks for the lock owned by task-A. This
+results in a priority boost for task-A. Task-B goes to sleep until the
+lock has been made available. Task-A is already runnable (but not active),
+so it receives no wake up.
+
+The reality now is that task-A gets on the CPU once the scheduler decides
+to remove the current task despite the fact that a high priority task is
+enqueued and waiting. This may take a long time.
+
+The desired behaviour is that CPU0 immediately reschedules after the
+priority boost which made task-A the task with the lowest priority.
+
