Catalin Marinas 2e82669acf ARM: 6867/1: Introduce THREAD_NOTIFY_COPY for copy_thread() hooks 
This patch adds THREAD_NOTIFY_COPY for calling registered handlers
during the copy_thread() function call. It also changes the VFP handler
to use a switch statement rather than if..else and ignore this event.

Russell King 797245f5da ARM: Convert VFP/Crunch/XscaleCP thread_release() to exit_thread() 
This avoids races in the VFP code where the dead thread may have
state on another CPU.  By moving this code to exit_thread(), we
will be running as the thread, and therefore be running on the
current CPU.

This means that we can ensure that the only local state is accessed
in the thread notifiers.
