      [IA64] - Avoid slow TLB purges on SGI Altix systems · c1902aae
      Dean Roe authored
      
      
      flush_tlb_all() can be a scaling issue on large SGI Altix systems
      since it uses the global call_lock and always executes on all cpus.
      When a process enters flush_tlb_range() to purge TLBs for another
      process, it is possible to avoid flush_tlb_all() and instead allow
      sn2_global_tlb_purge() to purge TLBs only where necessary.
      
      This patch modifies flush_tlb_range() so that this case can be handled
      by platform TLB purge functions and updates ia64_global_tlb_purge()
      accordingly.  sn2_global_tlb_purge() now calculates the region register
      value from the mm argument introduced with this patch.

      [IA64] Cleanup use of various #defines related to nodes · 24ee0a6d
      Jack Steiner authored
      
      
      Some of the SN code & #defines related to compact nodes & IO discovery
      have gotten stale over the years. This patch attempts to clean them up.
      Some of the various SN MAX_xxx #defines were also unclear & misused.
      
      The primary changes are:
      
      	- use MAX_NUMNODES. This is the generic linux #define for the number
      	  of nodes that are known to the generic kernel. Arrays & loops
      	  for constructs that are 1:1 with linux-defined nodes should
      	  use the linux #define - not an SN equivalent.
      
      	- use MAX_COMPACT_NODES for MAX_NUMNODES + NUM_TIOS. This is the
      	  number of nodes in the SSI system. Compact nodes are a hack to
      	  get around the IA64 architectural limit of 256 nodes. Large SGI
      	  systems have more than 256 nodes. When we upgrade to ACPI3.0,
      	  I _hope_ that all nodes will be real nodes that are known to
      	  the generic kernel. That will allow us to delete the notion
      	  of "compact nodes".
      
      	- add MAX_NUMALINK_NODES for the total number of nodes that
      	  are in the numalink domain - all partitions.
      
      	- simplified (understandable) scan_for_ionodes()
      
      	- small amount of cleanup related to cnodes

      [IA64] sparse cleanup of shub_mmr.h · 8e4641b3
      Prarit Bhargava authored
      
      
      This patch is a sparse compile cleanup of shub_mmr.h using both the defconfig
      and the sn2_defconfig config files.
      
      The issue with this file was the missing usage of __IA64_UL_CONST wrapper.
      This wrapper is defined in include/asm-ia64/types.h and wraps a long
      constant definition with UL or with nothing depending on its usage in the
      kernel.  The missing wrapper caused many sparse compile errors like
      
              warning: constant 0x0x0000000010000380 so big it is long

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
