David S. Miller f076216468 Correct libthreadb register access for 64-bit sparc. 
[BZ #14568]
	* sysdeps/sparc/tls.h (DB_THREAD_SELF_INCLUDE): Delete.
	(DB_THREAD_SELF): Use constants for the register offsets.  Correct
	the case of a 64-bit debugger with a 32-bit inferior.

Siddhesh Poyarekar c30e8edf7c Unlock mutex before going back to waiting for PI mutexes 
[BZ #14417]
A futex call with FUTEX_WAIT_REQUEUE_PI returns with the mutex locked
on success.  If such a successful thread is pipped to the cond_lock by
another spuriously woken waiter, it could be sent back to wait on the
futex with the mutex lock held, thus causing a deadlock.  So it is
necessary that the thread relinquishes the mutex before going back to
sleep.

Siddhesh Poyarekar 55a051c985 Fix exception table for i386 pthread_cond_wait 
[BZ #14477]
Add an additional entry in the exception table to jump to
__condvar_w_cleanup2 instead of __condvar_w_cleanup for PI mutexes
when %ebx contains the address of the futex instead of the condition
variable.

Alan Modra 7e2fca8dd2 Fix bugs in powerpc pthread_once. 
Ref gcc.gnu.org/bugzilla/show_bug.cgi?id=52839#c10

Release barriers are needed to ensure that any memory written by
init_routine is seen by other threads before *once_control changes.
In the case of clear_once_control we need to flush any partially
written state.

Siddhesh Poyarekar 439bf404b8 Allow a single-threaded program to cancel itself 
There is nothing in the POSIX specification to disallow a
single-threaded program from cancelling itself, so we forcibly enable
multiple_threads to allow the next available cancellation point in the
thread to run.

Also added additional tests to cover various cancellation scenarios.
