+Subject: x86: Do not disable preemption in int3 on 32bit
+From: Steven Rostedt <rostedt at goodmis.org>
+
+Preemption must be disabled before enabling interrupts in do_trap
+on x86_64 because the stack in use for int3 and debug is a per CPU
+stack set by th IST. But 32bit does not have an IST and the stack
+still belongs to the current task and there is no problem in scheduling
+out the task.
+
+Keep preemption enabled on X86_32 when enabling interrupts for
+do_trap().
+
+The name of the function is changed from preempt_conditional_sti/cli()
+to conditional_sti/cli_ist(), to annotate that this function is used
+when the stack is on the IST.

+Subject: futex: Fix bug on when a requeued RT task times out
+From: Steven Rostedt <rostedt at goodmis.org>
+
+Requeue with timeout causes a bug with PREEMPT_RT_FULL.
+
+The bug comes from a timed out condition.
+
+
+ TASK 1 TASK 2
+ ------ ------
+ futex_wait_requeue_pi()
+ futex_wait_queue_me()
+ <timed out>
+
+ double_lock_hb();
+
+ raw_spin_lock(pi_lock);
+ if (current->pi_blocked_on) {
+ } else {
+ current->pi_blocked_on = PI_WAKE_INPROGRESS;
+ run_spin_unlock(pi_lock);
+ spin_lock(hb->lock); <-- blocked!
+
+
+ plist_for_each_entry_safe(this) {
+ rt_mutex_start_proxy_lock();
+ task_blocks_on_rt_mutex();
+ BUG_ON(task->pi_blocked_on)!!!!
+
+The BUG_ON() actually has a check for PI_WAKE_INPROGRESS, but the
+problem is that, after TASK 1 sets PI_WAKE_INPROGRESS, it then tries to
+grab the hb->lock, which it fails to do so. As the hb->lock is a mutex,
+it will block and set the "pi_blocked_on" to the hb->lock.
+
+When TASK 2 goes to requeue it, the check for PI_WAKE_INPROGESS fails
+because the task1's pi_blocked_on is no longer set to that, but instead,
+set to the hb->lock.
+
+The fix:
+
+When calling rt_mutex_start_proxy_lock() a check is made to see
+if the proxy tasks pi_blocked_on is set. If so, exit out early.
+Otherwise set it to a new flag PI_REQUEUE_INPROGRESS, which notifies
+the proxy task that it is being requeued, and will handle things
+appropriately.

+Subject: genirq: Allow disabling of softirq processing in irq thread context
+From: Thomas Gleixner <tglx at linutronix.de>
+Date: Tue, 31 Jan 2012 13:01:27 +0100
+
+The processing of softirqs in irq thread context is a performance gain
+for the non-rt workloads of a system, but it's counterproductive for
+interrupts which are explicitely related to the realtime
+workload. Allow such interrupts to prevent softirq processing in their
+thread context.

+Subject: signal/x86: Delay calling signals in atomic
+From: Oleg Nesterov <oleg at redhat.com>
+
+On x86_64 we must disable preemption before we enable interrupts
+for stack faults, int3 and debugging, because the current task is using
+a per CPU debug stack defined by the IST. If we schedule out, another task
+can come in and use the same stack and cause the stack to be corrupted
+and crash the kernel on return.
+
+When CONFIG_PREEMPT_RT_FULL is enabled, spin_locks become mutexes, and
+one of these is the spin lock used in signal handling.
+
+Some of the debug code (int3) causes do_trap() to send a signal.
+This function calls a spin lock that has been converted to a mutex
+and has the possibility to sleep. If this happens, the above issues with
+the corrupted stack is possible.
+
+Instead of calling the signal right away, for PREEMPT_RT and x86_64,
+the signal information is stored on the stacks task_struct and
+TIF_NOTIFY_RESUME is set. Then on exit of the trap, the signal resume
+code will send the signal when preemption is enabled.
+
+[ rostedt: Switched from #ifdef CONFIG_PREEMPT_RT_FULL to
+ ARCH_RT_DELAYS_SIGNAL_SEND and added comments to the code. ]

+Subject: timer-fd: Prevent live lock
+From: Thomas Gleixner <tglx at linutronix.de>
+Date: Wed, 25 Jan 2012 11:08:40 +0100
+
+If hrtimer_try_to_cancel() requires a retry, then depending on the
+priority setting te retry loop might prevent timer callback completion
+on RT. Prevent that by waiting for completion on RT, no change for a
+non RT kernel.
