  • target-cris/op.c: Make sure the bit-test insn only updates the XNZ flags.
  • target-cris/helper.c: Update ERP for user-mode simulation aswell.
  • hw/etraxfs_timer.c: Support multiple timers.
  • hw/etraxfs_ser.c: Multiple ports, the data just goes to stdout....

Replace is_user variable with mmu_idx in softmmu core,
allowing support of more than 2 mmu access modes.
Add backward compatibility is_user variable in targets code when needed.
Implement per target cpu_mmu_index function, avoiding duplicated code
and #ifdef TARGET_xxx in softmmu core functions....
