commit 4f2bcda964d4fff56855e0c66198c9bcb682ea1e
Author: Will Newton <will.newton@linaro.org>
Date: Thu Aug 29 20:10:26 2013 +0100
ARM: Fix clone code when built for Thumb.
The mov lr, pc instruction will lose the Thumb bit from the return address
so use blx lr instead.

commit 2770d15e7e880821fc586619c59eb45180628e16
Author: Siddhesh Poyarekar <siddhesh@redhat.com>
Date: Thu Oct 3 08:26:21 2013 +0530
Fix PI mutex check in pthread_cond_broadcast and pthread_cond_signal
Fixes BZ #15996.
The check had a typo - it checked for PTHREAD_MUTEX_ROBUST_NP instead
of PTHREAD_MUTEX_ROBUST_NORMAL_NP. It has now been replaced by the
already existing convenience macro USE_REQUEUE_PI.
