      This bitop does not need to be atomic because it is performed when there will

      [PATCH] mm: remap ZERO_PAGE mappings · 9a61c349
      Nick Piggin authored
      filemap_xip's nopage routine maps the ZERO_PAGE into readonly mappings, if it
      has no data page to map there: then if the hole in the file is later filled,
      __xip_unmap uses an rmap technique to replace the ZERO_PAGEs mapped for that
      offset by the newly allocated file page, so that established mappings will see
      the newly written data.
      
      However, on MIPS (alone) there's not one but as many as eight ZERO_PAGEs,
      chosen for coloring by user virtual address; and if mremap has meanwhile been
      used to move a mapping containing a ZERO_PAGE, it will generally not match the
      ZERO_PAGE(address) __xip_unmap is looking for.
      
      To maintain XIP's established mappings correctly on MIPS, we need Nick's fix
      to mremap's move_one_page (originally presented as an optimization), to
      replace the ZERO_PAGE appropriate to the old address by the ZERO_PAGE
      appropriate to the new address.
      
      (But when I first saw this, I was thinking the ZERO_PAGEs themselves would get
      corrupted, very bad.  Now I think it's the other way round, that the
      established mappings will fail to see the newly written data: incorrect, but
      not corrupting everything else.  Whether filemap_xip's technique is generally
      safe, I'd hesitate to say in a hurry: it's interesting, but we've never tried
      to do that in tmpfs.)

      [PATCH] /proc/<pid>/numa_maps to show on which nodes pages reside · 6e21c8f1
      Christoph Lameter authored
      This patch was recently discussed on linux-mm:
      http://marc.theaimsgroup.com/?t=112085728500002&r=1&w=2
      
      I inherited a large code base from Ray for page migration.  There was a
      small patch in there that I find to be very useful since it allows the
      display of the locality of the pages in use by a process.  I reworked that
      patch and came up with a /proc/<pid>/numa_maps that gives more information
      about the vma's of a process.  numa_maps is indexes by the start address
      found in /proc/<pid>/maps.  F.e.  with this patch you can see the page use
      of the "getty" process:

      Remove the three get_mm_counter(mm, rss) tests from rmap.c: there was a

      [PATCH] swap: swap_lock replace list+device · 5d337b91
      Hugh Dickins authored
      The idea of a swap_device_lock per device, and a swap_list_lock over them all,
      is appealing; but in practice almost every holder of swap_device_lock must
      already hold swap_list_lock, which defeats the purpose of the split.
      
      The only exceptions have been swap_duplicate, valid_swaphandles and an
      untrodden path in try_to_unuse (plus a few places added in this series).
      valid_swaphandles doesn't show up high in profiles, but swap_duplicate does
      demand attention.  However, with the hold time in get_swap_pages so much
      reduced, I've not yet found a load and set of swap device priorities to show
      even swap_duplicate benefitting from the split.  Certainly the split is mere
      overhead in the common case of a single swap device.
      
      So, replace swap_list_lock and swap_device_lock by spinlock_t swap_lock
      (generally we seem to prefer an _ in the name, and not hide in a macro).
      
      If someone can show a regression in swap_duplicate, then probably we should
      add a hashlock for the swap_map entries alone (shorts being anatomic), so as
      to help the case of the single swap device too.

      [PATCH] swap: scan_swap_map drop swap_device_lock · 52b7efdb
      Hugh Dickins authored
      get_swap_page has often shown up on latency traces, doing lengthy scans while
      holding two spinlocks.  swap_list_lock is already dropped, now scan_swap_map
      drop swap_device_lock before scanning the swap_map.
      
      While scanning for an empty cluster, don't worry that racing tasks may
      allocate what was free and free what was allocated; but when allocating an
      entry, check it's still free after retaking the lock.  Avoid dropping the lock
      in the expected common path.  No barriers beyond the locks, just let the
      cookie crumble; highest_bit limit is volatile, but benign.
      
      Guard against swapoff: must check SWP_WRITEOK before allocating, must raise
      SWP_SCANNING reference count while in scan_swap_map, swapoff wait for that to
      fall - just use schedule_timeout, we don't want to burden scan_swap_map
      itself, and it's very unlikely that anyone can really still be in
      scan_swap_map once swapoff gets this far.

      Hugh Dickins authored
      The "Adding %dk swap" message shows the number of swap extents, as a guide to
      how fragmented the swapfile may be.  But a useful further guide is what total
      extent they span across (sometimes scarily large).
      
      And there's no need to keep nr_extents in swap_info: it's unused after the

      [PATCH] swap: swap extent list is ordered · 11d31886
      Hugh Dickins authored
      There are several comments that swap's extent_list.prev points to the lowest
      extent: that's not so, it's extent_list.next which points to it, as you'd
      expect.  And a couple of loops in add_swap_extent which go all the way through
      the list, when they should just add to the other end.
      
      Fix those up, and let map_swap_page search the list forwards: profiles shows
      it to be twice as quick that way - because prefetch works better on how the
      structs are typically kmalloc'ed?  or because usually more is written to than
      read from swap, and swap is allocated ascendingly?

      swap_list_unlock, which is faintly unsafe: another sys_swapon might already be
      setting up that swap_info_struct.  Calling it earlier, before taking
      swap_list_lock, is safe.  sys_swapoff's call to destroy_swap_extents was safe,
      but likewise move it earlier, before taking the locks (once try_to_unuse has
      completed, nothing can be needing the swap extents).

      [PATCH] swap: correct swapfile nr_good_pages · e2244ec2
      Hugh Dickins authored
      If a regular swapfile lies on a filesystem whose blocksize is less than
      PAGE_SIZE, then setup_swap_extents may have to cut the number of usable swap
      pages; but sys_swapon's nr_good_pages was not expecting that.  Also,
      setup_swap_extents takes no account of badpages listed in the swap header: not
      worth doing so, but ensure nr_badpages is 0 for a regular swapfile.

      [PATCH] mm: consolidate get_order · fd4fd5aa
      Stephen Rothwell authored
      Someone mentioned that almost all the architectures used basically the same
      implementation of get_order.  This patch consolidates them into
      asm-generic/page.h and includes that in the appropriate places.  The
      exceptions are ia64 and ppc which have their own (presumably optimised)
      versions.

      [PATCH] sparsemem extreme: hotplug preparation · 28ae55c9
      Dave Hansen authored
      This splits up sparse_index_alloc() into two pieces.  This is needed
      because we'll allocate the memory for the second level in a different place
      from where we actually consume it to keep the allocation from happening
      underneath a lock

      [PATCH] sparsemem extreme implementation · 3e347261
      Bob Picco authored
      With cleanups from Dave Hansen <haveblue@us.ibm.com>
      
      SPARSEMEM_EXTREME makes mem_section a one dimensional array of pointers to
      mem_sections.  This two level layout scheme is able to achieve smaller
      memory requirements for SPARSEMEM with the tradeoff of an additional shift
      and load when fetching the memory section.  The current SPARSEMEM
      implementation is a one dimensional array of mem_sections which is the
      default SPARSEMEM configuration.  The patch attempts isolates the
      implementation details of the physical layout of the sparsemem section
      array.
      
      SPARSEMEM_EXTREME requires bootmem to be functioning at the time of
      memory_present() calls.  This is not always feasible, so architectures
      which do not need it may allocate everything statically by using
      SPARSEMEM_STATIC.

      [PATCH] SPARSEMEM EXTREME · 802f192e
      Bob Picco authored
      A new option for SPARSEMEM is ARCH_SPARSEMEM_EXTREME.  Architecture
      platforms with a very sparse physical address space would likely want to
      select this option.  For those architecture platforms that don't select the
      option, the code generated is equivalent to SPARSEMEM currently in -mm.
      I'll be posting a patch on ia64 ml which uses this new SPARSEMEM feature.
      
      ARCH_SPARSEMEM_EXTREME makes mem_section a one dimensional array of
      pointers to mem_sections.  This two level layout scheme is able to achieve
      smaller memory requirements for SPARSEMEM with the tradeoff of an
      additional shift and load when fetching the memory section.  The current
      SPARSEMEM -mm implementation is a one dimensional array of mem_sections
      which is the default SPARSEMEM configuration.  The patch attempts isolates
      the implementation details of the physical layout of the sparsemem section
      array.
      
      ARCH_SPARSEMEM_EXTREME depends on 64BIT and is by default boolean false.
      
      I've boot tested under aim load ia64 configured for ARCH_SPARSEMEM_EXTREME.
       I've also boot tested a 4 way Opteron machine with !ARCH_SPARSEMEM_EXTREME
      and tested with aim.

      Marcel Selhorst authored
      This patch corrects the PNP-handling inside the tpm-driver
      and some minor coding style bugs.
      Note: the pci-device and pnp-device mixture is currently necessary,
      since the used "tpm"-interface requires a pci-dev in order to register
      the driver. This will be fixed within the next iterations.
