This patch builds support for the new conversions of physical addresses to and from sockets, pnodes and nodes in UV4. It is designed to be as efficient as possible as lookups are done inside an interrupt context in some cases. It will be further optimized when physical hardware is available to measure execution time.

UV4 uses a GAM (globally addressed memory) architecture that supports variable sized memory per node. This replaces the old "M" value (number of address bits per node) with a range table for conversions between addresses and physical node (pnode) id's. This table is obtained from UV BIOS via the EFI UVsystab table. Support for older EFI UVsystab tables is maintained.

Allocate and setup per node hub info structs. CPU 0/Node 0 hub info is statically allocated to be accessible early in system startup. The remaining hub info structs are allocated on the node's local memory, and shared among the CPU's on that node. This leaves the small amount of info unique to each CPU in the per CPU info struct. Memory is saved by combining the common per node info fields to common node local structs. In addtion, since the info is read only only after setup, it should stay in the L3 cache of the local processor socket. This should therefore improve the cache hit rate when a group of cpus on a node are all interrupted for a common task.

This adds the MMR definitions for UV4 via an automated script that uses the output from a hardware verilog code to symbol converter.

With this switch, the immediate panic can be replaced with a message and a bad return value allowing either hardware or the emulator to diagnose the problem. It allows functions common to some UV arches to use common defines that might not be fully defined for all arches, as long as they do not reference them on the unsupported arches.

Pull rdma fixes from Doug Ledford: "Final set of -rc fixes for 4.6. I've collected up a number of patches that are all pretty small with the exception of only a couple. The hfi1 driver has a number of important patches, and it is what really drives the line count of this pull request up. These are all small and I've got this kernel built and running in the test lab (I have most of the hardware, I think nes is the only thing in this patch set that I can't say I've personally tested and have up and running).

Both of these drivers can return NOTIFY_BAD, but this terminates processing other callbacks that were registered later on the chain. Since the driver did nothing to log the error it seems wrong to prevent other interested parties from seeing it. E.g. neither of them had even bothered to check the type of the error to see if it was a memory error before the return NOTIFY_BAD.
