exit_pi_state() is called from do_exit() but not from do_execve(). Move it to release_mm() so it gets called from do_execve() as well.

The robust list pointers of user space held futexes are kept intact over an exec() call. When the exec'ed task exits exit_robust_list() is called with the stale pointer. The risk of corruption is minimal, but still it is incorrect to keep the pointers valid. Actually glibc should uninstall the robust list before calling exec() but we have to deal with it anyway. Nullify the pointers after [compat_]exit_robust_list() has been called.

Rich reported a lock imbalance in the futex code: http://bugzilla.kernel.org/show_bug.cgi?id=14288 It's caused by the displacement of the retry_private label in futex_wake_op(). The code unlocks the hash bucket locks in the error handling path and retries without locking them again which makes the next unlock fail. Move retry_private so we lock the hash bucket locks when we retry.

Commit ffd71da4 ("panic: decrease oops_in_progress only after having done the panic") moved bust_spinlocks(0) to the end of the function, which in practice is never reached. As a result console_unblank() is not called, and on some systems the user may not see the panic message. Move it back up to before the unblanking.

The rcu_barrier enum causes several problems: (1) you have to define the enum somewhere, and there is no convenient place, (2) the difference between TREE_RCU and TREE_PREEMPT_RCU causes problems when you need to map from rcu_barrier enum to struct rcu_state, (3) the switch statement are large, and (4) TINY_RCU really needs a different rcu_barrier() than do the treercu implementations. So replace it with a functionally equivalent but cleaner function pointer abstraction. Signed-off-by: NPaul E.

These issues identified during an old-fashioned face-to-face code review extending over many hours. This group improves an existing abstraction and introduces two new ones. It also fixes an RCU stall-warning bug found while making the other changes. o Make RCU_INIT_FLAVOR() declare its own variables, removing the need to declare them at each call site. o Create an rcu_for_each_leaf() macro that scans the leaf nodes of the rcu_node tree. o Create an rcu_for_each_node_breadth_first() macro that does a breadth-first traversal of the rcu_node tree, AKA stepping through the array in index-number order. o If all CPUs corresponding to a given leaf rcu_node structure go offline, then any tasks queued on that leaf will be moved to the root rcu_node structure. Therefore, the stall-warning code must dump out tasks queued on the root rcu_node structure as well as those queued on the leaf rcu_node structures. Signed-off-by: NPaul E.

PI futexes do not use the same plist_node_empty() test for wakeup. It was possible for the waiter (in futex_wait_requeue_pi()) to set TASK_INTERRUPTIBLE after the waker assigned the rtmutex to the waiter. The waiter would then note the plist was not empty and call schedule(). The task would not be found by any subsequeuent futex wakeups, resulting in a userspace hang. By moving the setting of TASK_INTERRUPTIBLE to before the call to queue_me(), the race with the waker is eliminated. Since we no longer call get_user() from within queue_me(), there is no need to delay the setting of TASK_INTERRUPTIBLE until after the call to queue_me(). The FUTEX_LOCK_PI operation is not affected as futex_lock_pi() relies entirely on the rtmutex code to handle schedule() and wakeup. The requeue PI code is affected because the waiter starts as a non-PI waiter and is woken on a PI futex. Remove the crusty old comment about holding spinlocks() across get_user() as we no longer do that. Correct the locking statement with a description of why the test is performed.

VGA arb requires DRM support for non-kms drivers, to turn on/off irqs when disabling the mem/io regions. VGA arb requires KMS support for GPUs where we can turn off VGA decoding. Currently we know how to do this for intel and radeon kms drivers, which allows them to be removed from the arbiter. This patch comes from Fedora rawhide kernel.
