      sparc: fix build fail in mm/init_64.c when NEED_MULTIPLE_NODES is off · aa6f0790
      Paul Gortmaker authored
      Commit 625d693e (linux-next)
      
          "sparc64: Convert over to NO_BOOTMEM."
      
      causes the following compile failure for sparc64 allnoconfig:
      
        arch/sparc/mm/init_64.c:822:16: error: unused variable 'paddr'
        arch/sparc/mm/init_64.c:1759:7: error: unused variable 'node'
        arch/sparc/mm/init_64.c:809:12: error: 'memblock_nid_range' defined but not used
      
      The paddr decl can easily be shuffled within the ifdef.  The
      memblock_nid_range is just a stub function for when NEED_MULTIPLE_NODES
      is off, but the only caller is within a NEED_MULTIPLE_NODES enabled
      section, so we can simply delete it.
      
      The unused "node" is slightly more interesting.  In the case of
      "# CONFIG_NEED_MULTIPLE_NODES is not set" we no longer get the
      definition of:
      
       #define NODE_DATA(nid)          (node_data[nid])
      
      from arch/sparc/include/asm/mmzone.h - but instead we get:
      
       #define NODE_DATA(nid)          (&contig_page_data)
      
      from include/linux/mmzone.h -- and since the arg is ignored,
      the thing really is unused.  Rather than put in a confusing
      looking __maybe_unused, simply splitting the declaration
      from the assignment seemed to me to be the least offensive.

      Commit 3268c63e ("mm: fix move/migrate_pages() race on task struct") has
      added an odd construct where 'mm' is checked for being NULL, and if it is,
      it would get dereferenced anyways by mput()ing it.

      added an odd construct where 'mm' is checked for being NULL, and if it is,
      it would get dereferenced anyways by mput()ing it.
      
      This would lead to the following NULL ptr deref and BUG() when calling

      Will Deacon authored
      Revert commit 85e72aa5 ("proc: clear_refs: do not clear reserved
      pages"), which was a quick fix suitable for -stable until ARM had been
      moved over to the gate_vma mechanism:
      
      https://lkml.org/lkml/2012/1/14/55
      
      With commit f9d4861f ("ARM: 7294/1: vectors: use gate_vma for vectors user
      mapping"), ARM does now use the gate_vma, so the PageReserved check can be
      removed from the proc code.
