Subject: [PATCH v4 00/13] x86/platform/uv: Updates for UV5 Architecture

Changes included in this patch set:

 * Add changes needed for new UV5 UV architecture.  Chief among the
   changes are 52 bits of physical memory address and 57 bits of
   virtual address space.

 * Remove the BAU TLB code cuurently being replaced by BAU APIC driver.

 * Remove System Controller (monitoring) code

 * Updated UV mmrs.h file removing UV1, adding UVY class, optimizing
   the arch selection of the MMR address/field, and trimming down MMR
   selection list reducing number of MMRs being defined.

 * Process UV ArchType in UV BIOS generated UVsystab allowing OEMs to
   use OEM_ID for their own purposes.

 * Update various mapping functions (MMIOH, MMR, GRU) to accommodate
   UV5 differences.

 * Update node present counting for change in MMRs.

 * Update TSC sync check of BIOS sync status.

 * Update NMI handler for UV5 MMR changes.

 * Update copyrights to conform to HPE standards.

This is version 4 with these changes since version 3: 

 * Fixed coding errors reported by kernel test robot <lkp@...el.com>

 - In [PATCH 04/13] x86/platform/uv: Update UV MMRs for UV5
     Remove pnodeid return from early_get_pnodeid() as it was only used by UV1.
     Remove read node_id in uv_init_hub_info() as it was no longer relevant.

 - In [PATCH v3 07/13] x86/platform/uv: Update MMIOH references based on new UV5 MMRs.
     Make calc_mmioh_map() a static function.

This is version 3 with these changes since version 2: 

 * Changes made to .gitconfig so no internal (unreachable) systems
   are referenced.

This is version 2 with these changes since version 1: 

 * Added diffstats to p-intro.

 * Updated Copyrights to be in one file and only include the year
   the code was modified.

 * Updated to use git format-patch to construct patch email and 
   git send-email to send the patches.
