  Log:
  Implement set_mcontext() and get_mcontext(). Just as for sendsig() and
  sigreturn(), we cheat and assume the preserved registers are still
  on-chip and unmodified. This is actually the case, but more by accident
  than by design. We need to use unwinding eventually or explicitly
  compile the kernel in a way that the compiler steers clear from using
  the preserved registers completely.
