* join.c (pthread_exit): Move code to new function __pthread_do_exit
which takes an extra parameter with the current frame pointer.
Call new function with CURRENT_STACK_FRAME.
(__pthread_do_exit): New function. Call __pthread_perform_cleanup
with the new parameter.
(pthread_join): Call __pthread_do_exit instead of pthread_exit.
* cancel.c (__pthread_perform_cleanup): Takes extra parameter. Use
this parameter as the initial value the cleanup handler records are
compared against. No active cleanup handler record must have an
address lower than the previous one and the initial record must be
above (below on PA) the frame address passed in.
(pthread_setcancelstate): Call __pthread_do_exit instead of
pthread_exit.
(pthread_setcanceltype): Likewise.
(pthread_testcancel): Likewise.
(_pthread_cleanup_pop_restore): Likewise.
* condvar.c (pthread_cond_wait): Likewise.
(pthread_cond_timedwait_relative): Likewise.
* manager.c (pthread_start_thread): Likewise.
* oldsemaphore.c (__old_sem_wait): Likewise.
* pthread.c (pthread_handle_sigcancel): Likewise.
* semaphore.c (__new_sem_wait): Likewise.
(sem_timedwait): Likewise.
* ptlongjmp.c (pthread_cleanup_upto): Also use current stack frame
to limit the cleanup handlers which get run.
* internals.h: Add prototype for __pthread_do_exit. Adjust prototype
for __pthread_perform_cleanup.

I think the loop was written for MMU case. When there is MMU, mmap ()
is used to allocate the stack. If one segment is already mapped, we
should continue to see if we can use the next one. However, for NOMMU,
malloc () is used. It's waste of CPU cycles to continue to try if it
fails. Here is a new patch, which makes this change only for NOMMU.
