* Mega patch merge to change the format of the object IDs to
loosen the dependency between the SCORE and the various APIs.
There was considerable work to simplify the object name management
and it appears that the name_table field is no longer needed.
This patch also includes the addition of the internal mutex
which is currently only used to protect some types of allocation
and deallocation. This significantly can reduce context
switch latency under certain circumstances. In particular,
some heap/region operations were O(n) and had dispatching
disabled. This should help enormously. With this merge,
the patch is not as clean as it should be. In particular,
the documentation has not been modified to reflect the new object
ID layout, the IDs in the test screens are not updated, and
_Objects_Get_information needs to be a real routine not inlined.
As part of this patch a lot of MP code for thread/proxy blocking
was made conditional and cleaned up.

2002-05-15 Chris Johns <ccj@acm.org>
* include/rtems/score/thread.h, inline/rtems/score/thread.inl,
src/threaddispatch.c, src/threadinitialize.c:
Move the C library re-enterrant support directly into
the thread dispatch code. RTEMS needs libc and so requiring
libc to use a user extension with its overhead is not the best
solution. This patch lowers the overhead to 2 pointer moves.
2002-05-03 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* include/Makefile.am: Work-around to autoconf-2.53 adding PACKAGE_*
to autoheaders - sed out *PACKAGE* from cpuopts-tmp.h.
2001-05-14 Till Straumann <strauman@slac.stanford.edu>
* src/threaddispatch.c, src/threadhandler.c: Per PR211 fix
saving/restoring floating point context. The fpsave and fprestore
routines are only used in a executing context which _is_ fp and hence
has the FPU enabled. The current behavior required the FPU always to
be on which is very dangerous if lazy context switching is used.
[Joel Note: Some ports explicitly enabled the FPU in the FP save and
restore routines to avoid this.]
The patch also makes sure (on powerpc only) that the FPU is disabled
for integer tasks. Note that this is crucial if deferred fp context
switching is used. Otherwise, fp context corruption may go undetected!
Also note that even tasks which merely push/pop FP registers to/from
the stack without modifying them still MUST be FP tasks - otherwise
(if lazy FP context switching is used), FP register corruption (of
other, FP, tasks may occur)!
Furthermore, (on PPC) by default, lazy FP context save/restore
is _disabled_.

2001-04-26 Joel Sherrill <joel@OARcorp.com>
* include/rtems/score/object.h, inline/rtems/score/object.inl,
src/objectcomparenamestring.c: Address PR81 that
reworked POSIX message queues to add a descriptor separate from
the underlying message queue. This allows non-blocking to follow
the "open" not the underlying queue. As part of debugging this
it became clear that _Objects_Compare_name_string was broken
and a simple version using strncmp() was substituted.

* src/coremutex.c, src/coremutexseize.c, src/coremutexsurrender.c,
inline/rtems/score/coremutex.inl: The per thread field resource_count
should only be manipulated when a mutex is priority ceiling or
priority inherit. This was reported by Chris Johns <ccj@acm.org>
who also noticed that the use of switches for all disciplines
generated less efficient code than using explicit tests for the one
or two cases we were really interested in. Further review of his
modifications made it apparent that the "isa" methods to test mutex
discipline were not being used so this modification was swept into
the code as well.
2001-08-30 Joel Sherrill <joel@OARcorp.com>
* src/coremutexseize.c: Add missing code for proper handling
of nesting acquisitions. This only impacts building with

* src/coremutexsurrender.c: Use holder thread not executing

* include/rtems/score/coremsg.h, src/coremsgsubmit.c: Add a new

* include/rtems/score/coremsg.h, inline/rtems/score/coremsg.inl,

* src/heapallocate.c: Do not allow the size to overflow when
adjusting it. A test allocated a stack of -1 (~0). This

size of 0xb. The allocator did not test the size to see if
it rolled through 0 and so allowed the allocation to happen, the
thread to get created. The task crashed as you would expect.

* include/rtems/system.h: Use proper conditional (RTEMS_POSIX_API)

* include/rtems/system.h: Add prototypes for POSIX_MP_NOT_IMPLEMENTED(),
POSIX_NOT_IMPLEMENTED(), POSIX_BOTTOM_REACHED() removed from newlib.
