+1. Need to figure out why PCI writes to the IOC3 hang, and if it is okay
+not to write to the IOC3 ever.
+2. Need to figure out RRB allocation in bridge_startup().
+3. Need to figure out why address swaizzling is needed in inw/outw for
+Qlogic scsi controllers.
+4. Need to integrate ip27-klconfig.c:find_lboard and
+ip27-init.c:find_lbaord_real. DONE
+5. Is it okay to set calias space on all nodes as 0, instead of 8k as
+in irix?
+6. Investigate why things do not work without the setup_test() call
+being invoked on all nodes in ip27-memory.c.
+7. Too many CLIs in the locore handlers :
+For the low level handlers set up by set_except_vector(),
+__tlb_refill_debug_tramp, __xtlb_refill_debug_tramp and cacheerror,
+investigate whether the code should do CLI, STI or KMODE.
+8. Too many do_page_faults invoked - investigate.
+9. start_thread must turn off UX64 ... and define tlb_refill_debug.
+10. Need a bad pmd table, bad pte table. __bad_pmd_table/__bad_pagetable
+does not agree with pgd_bad/pmd_bad.
+11. All intrs (ip27_do_irq handlers) are targetted at cpu A on the node.
+This might need to change later. Only the timer intr is set up to be
+received on both Cpu A and B. (ip27_do_irq()/bridge_startup())
+13. Cache flushing (specially the SMP version) has to be investigated.
