a6342974b0 Fix exception stack frame for or1k 
- We do not need a red zone here, as we do not operate on the current
  stack, but always use the clear exception stack. Also reserve two
  extra words for the context to store EPCR and ESR.

    * or1k/crt0.S: Fix exception stack frame
    * or1k/exception-asm.S: ditto

132030fcf2 Fix interrupt handling for or1k. 
- During interrupt handling the PICSR, table pointers and current
  interrupt line have been saved in incorrect registers and/or stored on
  the stack.

- Save the pointer in r16/r18, PICSR in r20 and the current interrupt
  line in r22. Those are callee-saved registers, so that the register
  values will be preserved.

        * or1k/interruts-asm.S: Change registers to callee-saved.
