No.  Why would userspace want to know about these entry points?

I'd also like to point you at two other commits I just made:

  http://www.linux-mips.org/g/linux/a599080f
  http://www.linux-mips.org/g/linux/3c339dba

The first deletes the unused sys_truncate64 and sys_ftruncate64 entry-points
and the second resolves conflicting prototypes for sys_pipe() - MIPS uses
it's own sys_pipe() which conflicts with the one declared in
<linux/syscalls.h>.  The patch below takes care of that and also includes
the ptrace.h which is needed to make <asm/syscalls.h> work without
relying on other headers having been included previously.  Could you fold
that into your patch?  Thanks,

  Ralf
