2012-11-05[S390,PPC] Implement FUTEX_WAIT_BITSET for timedwait functionsSiddhesh Poyarekar7-6/+124
Since the FUTEX_WAIT operation takes a relative timeout, the pthread_cond_timedwait and other timed function implementations have to get a relative timeout from the absolute timeout parameter it gets before it makes the futex syscall. This value is then converted back into an absolute timeout within the kernel. This is a waste and has hence been improved upon by a FUTEX_WAIT_BITSET operation (OR'd with FUTEX_CLOCK_REALTIME to make the kernel use the realtime clock instead of the default monotonic clock). This was implemented only in the x86 and sh assembly code and not in the C code. This patch implements support for FUTEX_WAIT_BITSET whenever available (since linux-2.6.29) for s390 and powerpc.

2012-10-10Fix formatting in nptl/sysdeps/pthread/pthread.h.Carlos O'Donell2-2/+6
The macro pthread_cleanup_push_defer_np in pthread.h has a misaligned line continuation marker. This marker was previously aligned, but recent changes have moved it out of alignment. This change realigns the marker. This also reduces the diff against the hppa version of pthread.h where the marker is aligned.
2012-10-10Take lock in pthread_cond_wait cleanup handler only when neededSiddhesh Poyarekar8-9/+367
[BZ #14652] When a thread waiting in pthread_cond_wait with a PI mutex is cancelled after it has returned successfully from the futex syscall but just before async cancellation is disabled, it enters its cancellation handler with the mutex held and simply calling a mutex_lock again will result in a deadlock. Hence, it is necessary to see if the thread owns the lock and try to lock it only if it doesn't.

2012-10-05Unlock mutex before going back to waiting for PI mutexesSiddhesh Poyarekar7-172/+427
[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.

[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.
