x86/platform/uv: Add platform resolving #defines for misc GAM_MMIOH_REDIRECT*
Upcoming changes will require use of new #defines UVH_RH_GAM_MMIOH_REDIRECT_CONFIG0_NASID_MASK and UVH_RH_GAM_MMIOH_REDIRECT_CONFIG1_NASID_MASK, which provide the appropriate values on different uv platforms.
Also, fix typo that defined a couple of "*_CONFIG0_*" values twice where "*_CONFIG1_*" was intended.

x86/platform/uv: Update UV MMRs for UV5
Update UV MMRs in uv_mmrs.h for UV5 based on Verilog output from the UV Hub hardware design files. This is the next UV architecture with a new class (UVY) being defined for 52 bit physical address masks. Uses a bitmask for UV arch identification so a single test can cover multiple versions. Includes other adjustments to match the uv_mmrs.h file to keep from encountering compile errors. New UV5 functionality is added in the patches that follow.

x86/platform/UV: Add UV4 Specific MMR definitions
This adds the MMR definitions for UV4 via an automated script that uses the output from a hardware verilog code to symbol converter. The large number of insertions is caused by the UV4 design changing many similarly named fields in MMR's that are named the same. This prompted the extra production of architecture dependent field defines.

x86/UV: Set n_lshift based on GAM_GR_CONFIG MMR for UV3
The value of n_lshift for UV is currently set based on the socket m_val.
For UV3, set the n_lshift value based on the GAM_GR_CONFIG MMR. This will allow bios to control the n_lshift value independent of the socket m_val. Then n_lshift can be assigned a fixed value across a multi-partition system, allowing for a fixed common global physical address format that is independent of socket m_val.
Cleanup unneeded macros.

x86/UV: Update UV support for external NMI signals
The current UV NMI handler has not been updated for the changes in the system NMI handler and the perf operations. The UV NMI handler reads an MMR in the UV Hub to check to see if the NMI event was caused by the external 'system NMI' that the operator can initiate on the System Mgmt Controller.
The problem arises when the perf tools are running, causing millions of perf events per second on very large CPU count systems. Previously this was okay because the perf NMI handler ran at a higher priority on the NMI call chain and if the NMI was a perf event, it would stop calling other NMI handlers remaining on the NMI call chain.
Now the system NMI handler calls all the handlers on the NMI call chain including the UV NMI handler. This causes the UV NMI handler to read the MMRs at the same millions per second rate. This can lead to significant performance loss and possible system failures. It also can cause thousands of 'Dazed and Confused' messages being sent to the system console. This effectively makes perf tools unusable on UV systems.
To avoid this excessive overhead when perf tools are running, this code has been optimized to minimize reading of the MMRs as much as possible, by moving to the NMI_UNKNOWN notifier chain. This chain is called only when all the users on the standard NMI_LOCAL call chain have been called and none of them have claimed this NMI.
There is an exception where the NMI_LOCAL notifier chain is used. When the perf tools are in use, it's possible that the UV NMI was captured by some other NMI handler and then either ignored or mistakenly processed as a perf event. We set a per_cpu ('ping') flag for those CPUs that ignored the initial NMI, and then send them an IPI NMI signal. The NMI_LOCAL handler on each cpu does not need to read the MMR, but instead checks the in memory flag indicating it was pinged. There are two module variables, 'ping_count' indicating how many requested NMI events occurred, and 'ping_misses' indicating how many stray NMI events. These most likely are perf events so it shows the overhead of the perf NMI interrupts and how many MMR reads were avoided.
This patch also minimizes the reads of the MMRs by having the first cpu entering the NMI handler on each node set a per HUB in-memory atomic value. (Having a per HUB value avoids sending lock traffic over NumaLink.) Both types of UV NMIs from the SMI layer are supported.

All the new MMR definitions are added in this patch. The patches that follow then update the references. The last patch is a "trim" patch which reduces the size of the MMR definitions file by about a third. This keeps "bi-sectability" in place as the intermediate patches would not compile correctly if the trimmed MMR defines were done first.

I fixed alignment of comments in the structure definitions.
Also aligned comments and most field definitions & values. Also sorted the defines for the SHIFT & MASK values for each MMR. This make the file visually much more acceptable.
Some of the symbol names are still quite long. The file is based on post-processing of verilog definitions that are used for the node controller chip design. Although some symbol names are not what I would chose, I would like to maintain compatibility with the names used by the chip designers. We have a number of cross-reference utilities & having common names is important.

This patch adds support for a new version of the SGI UV hub chip. The hub chip is the node controller that connects multiple blades into a larger coherent SSI.
For the most part, UV2 is compatible with UV1. The majority of the changes are in the addresses of MMRs and in a few cases, the contents of MMRs. These changes are the result in changes in the system topology such as node configuration, processor types, maximum nodes, physical address sizes, etc.

This fixes problems seen on UV systems handling NMIs from the node controller.
I isolated the "dazed..." messages that I saw earlier to a bug in the BMC on our platform. It was sending NMIs w/o properly setting a register that indicated the source of NMI.
So rather than _assuming_ any unhandled NMI came from the UV system maintenance console (SMC), add a check to verify that the SMC actually sent the NMI.

This patch for SGI UV systems addresses a problem whereby interrupt transactions being looped back from a local IOH, through the hub to a local CPU can (erroneously) conflict with IO port operations and other transactions.
To workaound this we set a high bit in the APIC IDs used for interrupts. This bit appears to be ignored by the sockets, but it avoids the conflict in the hub.
