sysmips syscall

[rajesh.palani@philips.com]

Hi,

   The following lines appear in the linuxthreads/sysdeps/mips/pt-machine.h 
file in version
LinuxThreads 2.1.2:

TODO: This version makes use of MIPS ISA 2 features.  It won't
   work on ISA 1.  These machines will have to take the overhead of
   a sysmips(MIPS_ATOMIC_SET, ...) syscall which isn't implemented
   yet correctly.  There is however a better solution for R3000
   uniprocessor machines possible.

My questions are:
1.  Is the sysmips syscall implemented correctly yet?
2.  What is the better solution for R3000 uniprocessor machines?
3.  Does anyone have a patch for LinuxThreads that supports MIPS ISA 1?

   Thanks and regards,

   Rajesh
