Merge in the pthread library. This is the linuxthreads library taken from

glibc 2.1.3 and ported to work with uClibc by Stefan Soucek and Erik Andersen
(me).  Stefan has hacked things up such that linuxthreads runs on MMU-less
systems (tested only on arm-nommu).  Erik cleaned things up and made it work
properly as a shared library.

+
+2000-02-13  Ulrich Drepper  <drepper@redhat.com>
+
+	* condvar.c (pthread_cond_timedwait_relative_old): Undo last patch
+	but keep the code around.  A bug in the kernel prevent us from

+	(pthread_cond_timedwait_relative_new): Likewise.
+	(PR libc/1597 and libc/1598).
+
+2000-02-01  Kaz Kylheku  <kaz@ashi.footprints.net>
+
+	* condvar.c (pthread_cond_timedwait_relative_old): Do tight
+	loop around nanosleep calls instead of around most of the function
+	(pthread_cond_timedwait_relative_new): Likewise.
+	body.  Got rid of backwards goto and one local.

+	(pthread_cond_timedwait_relative_new): Likewise.
+	Patch by khendricks@ivey.uwo.ca (PR libc/1561).
+
+2000-01-18  Ulrich Drepper  <drepper@cygnus.com>
+
+	* manager.c (pthread_allocate_stack): Compute guard page address
+	correctly.  Patch by HJ Lu.
+
+2000-01-12  Ulrich Drepper  <drepper@cygnus.com>
+
+	* internals.h (pthread_readlock_info): New structure.
+	(_pthread_descr_struct): Add p_readlock_list, p_readlock_free, and

+
+2000-01-03  Kaz Kylheku  <kaz@ashi.footprints.net>
+
+	Redesigned how cancellation unblocks a thread from internal
+	cancellation points (sem_wait, pthread_join,
+	pthread_cond_{wait,timedwait}).
+	Cancellation won't eat a signal in any of these functions
+	(*required* by POSIX and Single Unix Spec!).
+	* condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
+	simultaneous condition variable signal (not required by POSIX
+	or Single Unix Spec, but nice).
+	* spinlock.c: __pthread_lock queues back any received restarts
+	that don't belong to it instead of assuming ownership of lock
+	upon any restart; fastlock can no longer be acquired by two threads
+	simultaneously.
+	* restart.h: Restarts queue even on kernels that don't have
+	queued real time signals (2.0, early 2.1), thanks to atomic counter,
+	avoiding a rare race condition in pthread_cond_timedwait.
+

+
+	* sysdeps/alpha/pt-machine.h:  Move stack_pointer definition to the

+	arg to prevent warning on 64bit machines.
+

+	before calling the callback function to report a new thread.

+
+	* linuxthreads/pthread.c: For i386, wrap pthread_handle_sigrestart

+	%gs from the signal context.  For each signal handling function,
+	two wrappers are required, one for a non-RT signal and one for
+	a RT signal.
+	* linuxthreads/signal.c: For i386, add code to restore %gs
+	from the signal context in pthread_sighandler and
+	pthread_sighandler_rt.
+
+1999-10-09  Andreas Jaeger  <aj@suse.de>
+
+	* internals.h: Add __new_sem_post to get prototype in
+	manager.c; include semaphore.h for needed types.
+
+1999-10-08  Ulrich Drepper  <drepper@cygnus.com>
+
+	* manager.c (__pthread_manager) [REQ_POST]: Use __new_sem_post
+	directly instead of calling sem_post which should not be necessary
+	but is faster and might help in some case to work around problems.
+
+1999-09-25  Ulrich Drepper  <drepper@cygnus.com>

+	* internals.h: Added p_nextlock entry to separate queueing for a
+	lock from queueing for a CV (sometimes a thread queues on a lock
+	to serialize removing itself from a CV queue).
+	* pthread.c: Added p_nextlock to initializers.
+	* spinlock.c: Changed to use p_nextlock instead of p_nextwaiting.
