More initial RMI files. Note that these so far do NOT compile and many of them may disappear. For example the xlr_boot1_console.c is old code that is ifdef'd out. I will clean these sorts of things up as I make progress on the port. So far the only thing I have I think straightened out is the bits around the interupt handling... and hey that may be broke ;-)

Some fixes to the current RMI interrupt handling, changes in this patch are: - (cleanup) remove rmi specific 'struct mips_intrhand' - this is no longer needed since 'struct intr_event' have all the required hooks - add xlr_cpu_establish_hardintr, which has args for pre/post ithread and filter hooks, so that the PCI code can add the PCI controller interrupt ack code here - make 'cpu_establish_hardintr' use the above function. - (fix) change type of eirr/eimr from register_t to uint64_t. These have to be 64bit otherwise we cannot handle interrupts from 32. - (fix) use eimr to mask eirr before checking interrupts, so that we will not handle masked interrupts. Obtained from: C.

This pushes all of JC's patches that I have in place. I am now able to run 32 cores ok.. but I still will hang on buildworld with a NFS problem. I suspect I am missing a patch for the netlogic rge driver. JC check and see if I am missing anything except your core-mask changes Obtained from: JC
