- spinlocks: Create atomic_spinlock and convert rq->lock · 34ca9f9b
  Thomas Gleixner authored Jul 24, 2009
```
atomic_spinlock_t will be used to annotate locks which are not
converted to sleeping spinlocks on preempt-rt.

rq->lock must be converted right away as rq->lock is handled by a few
raw lock operations.

Fix also the plist implementation so debugging can handle both
spinlocks and atomic_spinlocks.

- locks: Split rwlocks from spinlocks · f7c0160a
  Thomas Gleixner authored Jul 25, 2009
```
Preparatory patch for atomic_spinlocks and preempt-rt. rwlocks are
always converted to sleeping locks on preempt-rt. Split the code so
the later preempt-rt conversions can be done by excluding the separate
files.

genirq: Fix UP compile failure caused by irq_thread_check_affinity · 61f38261

Bruno Premont authored Jul 22, 2009

Since genirq: Delegate irq affinity setting to the irq thread
(591d2fb0) compilation with
CONFIG_SMP=n fails with following error:

/usr/src/linux-2.6/kernel/irq/manage.c:
   In function 'irq_thread_check_affinity':
/usr/src/linux-2.6/kernel/irq/manage.c:475:
   error: 'struct irq_desc' has no member named 'affinity'
make[4]: *** [kernel/irq/manage.o] Error 1

That commit adds a new function irq_thread_check_affinity() which
uses struct irq_desc.affinity which is only available for CONFIG_SMP=y.
Move that function under #ifdef CONFIG_SMP.

lockdep: Fix lockdep annotation for pipe_double_lock() · 023d43c7

Peter Zijlstra authored Jul 21, 2009

The presumed use of the pipe_double_lock() routine is to lock 2 locks in
a deadlock free way by ordering the locks by their address. However it
fails to keep the specified lock classes in order and explicitly
annotates a deadlock.

Rectify this.
