* cpu_asm.S: Fixed a sneaky return from int w/ ints disabled bug.
* rtems/score/cpu.h: Fixed register numbering in comments and made
interrupt enable/disable more robust.
* cpu_asm.S: Added support for the debug exception vector, cleaned
up the exception processing & exception return stuff. Re-added
EPC in the task context structure so the gdb stub will know where
a thread is executing. Should've left it there in the first place...
* idtcpu.h: Added support for the debug exception vector.
* cpu.c: Added ___exceptionTaskStack to hold a pointer to the
stack frame in an interrupt so context switch code can get the
userspace EPC when scheduling.
* rtems/score/cpu.h: Re-added EPC to the task context.
* src/pthreadonce.c: Task is not preemptable while running a
pthread_once init function. This is slightly less heavy handed
than disabling dispatching and seems better than consuming a mutex.
* libc/gxx_wrappers.c: Task is not preemptable while running a
pthread_once init function. This is slightly less heavy handed
than disabling dispatching and seems better than consuming a mutex.
* cpu_asm.S: Fixed exception return address, modified FP context
switch so FPU is properly enabled and also doesn't screw up the
exception FP handling.
* idtcpu.h: Added C0_TAR, the MIPS target address register used for
returning from exceptions.
* iregdef.h: Added R_TAR to the stack frame so the target address
can be saved on a per-exception basis. The new entry is past the
end of the frame gdb cares about, so doesn't affect gdb or cpu.h
stuff.
* rtems/score/cpu.h: added an #ifdef so cpu_asm.S can include it
to obtain FPU defines without systax errors generated by the C
defintions.
* cpu.c: Improved interrupt level saves & restores.
* Submitted by Victor V. Vengerov <vvv@oktet.ru> and merged
into the RTEMS source.
* ChangeLog, Makefile.am, README, configure.ac, include/Makefile.am,
include/rtems/bdbuf.h, include/rtems/blkdev.h, include/rtems/diskdevs.h,
include/rtems/ramdisk.h, include/rtems/.cvsignore, include/.cvsignore,
src/Makefile.am, src/bdbuf.c, src/blkdev.c, src/diskdevs.c,
src/ramdisk.c, src/.cvsignore, .cvsignore: New files.
* net/if_ppp.c, pppd/auth.c, pppd/chat.c, pppd/pppd.h,
pppd/sys-rtems.c: Add server with pap-authorization
capabilities as well as eliminate some warnings.
* net/radix.c: Properly handle fetching the default route when there
is no route. This was a bug in the original FreeBSD code and this
fix is from an updated version of their code.
* cpu_asm.S: Enhanced to save/restore more registers on
exceptions.
* rtems/score/cpu.h (CPU_Interrupt_frame): Enhanced to list every
register individually and document when it is saved.
* idtcpu.h: Added constants for the coprocessor 1 registers
revision and status.
* rtems.ads, rtems.adb: Formatting cleaned up. Task based timer
directives added. This is Timer_Initiate_Server,
Timer_Server_Fire_After, and Timer_Server_Fire_When.
* pppd/rtemspppd.c (rtems_pppd_disconnect): Modified to avoid bringing
the link down too fast.
NOTE: Mike reports successfully running at 56K baud on a direct link.
* cpu.c: Enhancements and fixes for modifying the SR when changing
the interrupt level.
* cpu_asm.S: Fixed handling of FP enable bit so it is properly
managed on a per-task basis, improved handling of interrupt levels,
and made deferred FP contexts work on the MIPS.
* rtems/score/cpu.h: Modified to support above changes.
* Nice Update of PPPD support which eliminates the
requiremetn that drivers be in the termios TASK_DRIVEN mode.
Mike did significant testing and reports that it seems to be
more stable and handle larger packets better. This patch
replaces the termios tasks with more general pppd network
driver tasks. The functions pppinput() and pppstart() get
called from the interrupt service routine.
* libc/termios.c: Added PPCDISC.
* Nice Update of PPPD support which eliminates the
requiremetn that drivers be in the termios TASK_DRIVEN mode.

of one of the task timer chains resulted in the Timer Server
task waking up too far in the future.
* Added rtems_timer_get_information() directive to support testing.
* src/timerserver.c, include/rtems/rtems/timer.h,
* src/timergetinfo.c: New file.
* src/Makefile.am: Modified to reflect above.
