I fixed the main reason why it was crashing on 2.4 - the 2.4 kernel
doesn't set the child's stack pointer on clone.  So I added code to
set the stack pointer in the child first thing.

I have updated the tarball at http://ozlabs.org/~paulus/.

Other changes include:

* removed the XCRF, JMPB0 and JMPB1 uCodes; they weren't being used
* removed LOAD_R and STORE_C, use LOCK; LOAD and LOCK; STORE instead
* made the icbi instruction (instruction cache block invalidate)
  invalidate the translation cache for the addressed cache line
* fix the thread startup for ppc
* added code to set the valid bits exactly for ADD and nearly exactly
  for CMP0.  (This reduces the number of errors detected on ls -l by
  about 75%. :)
