      [PATCH] bootmem: remove useless __init in header file · 2d1a07d4
      Franck Bui-Huu authored
      
      
      __init in headers is pretty useless because the compiler doesn't check it, and
      they get out of sync relatively frequently.  So if you see an __init in a
      header file, it's quite unreliable and you need to check the definition
      anyway.

      [PATCH] convert i386 NUMA KVA space to bootmem · 91023300
      keith mannthey authored
      
      
      Address a long standing issue of booting with an initrd on an i386 numa
      system.  Currently (and always) the numa kva area is mapped into low memory
      by finding the end of low memory and moving that mark down (thus creating
      space for the kva).  The issue with this is that Grub loads initrds into
      this similar space so when the kernel check the initrd it finds it outside
      max_low_pfn and disables it (it thinks the initrd is not mapped into usable
      memory) thus initrd enabled kernels can't boot i386 numa :(
      
      My solution to the problem just converts the numa kva area to use the
      bootmem allocator to save it's area (instead of moving the end of low
      memory).  Using bootmem allows the kva area to be mapped into more diverse
      addresses (not just the end of low memory) and enables the kva area to be
      mapped below the initrd if present.
      
      I have tested this patch on numaq(no initrd) and summit(initrd) i386 numa
      based systems.

      [PATCH] mm: msync() cleanup · 204ec841
      Peter Zijlstra authored
      
      
      With the tracking of dirty pages properly done now, msync doesn't need to scan
      the PTEs anymore to determine the dirty status.
      
      From: Hugh Dickins <hugh@veritas.com>
      
      In looking to do that, I made some other tidyups: can remove several
      #includes, and sys_msync loop termination not quite right.
      
      Most of those points are criticisms of the existing sys_msync, not of your
      patch.  In particular, the loop termination errors were introduced in 2.6.17:
      I did notice this shortly before it came out, but decided I was more likely to
      get it wrong myself, and make matters worse if I tried to rush a last-minute
      fix in.  And it's not terribly likely to go wrong, nor disastrous if it does
      go wrong (may miss reporting an unmapped area; may also fsync file of a
      following vma).

      [PATCH] mm: tracking shared dirty pages · d08b3851
      Peter Zijlstra authored
      
      
      Tracking of dirty pages in shared writeable mmap()s.
      
      The idea is simple: write protect clean shared writeable pages, catch the
      write-fault, make writeable and set dirty.  On page write-back clean all the
      PTE dirty bits and write protect them once again.
      
      The implementation is a tad harder, mainly because the default
      backing_dev_info capabilities were too loosely maintained.  Hence it is not
      enough to test the backing_dev_info for cap_account_dirty.
      
      The current heuristic is as follows, a VMA is eligible when:
       - its shared writeable
          (vm_flags & (VM_WRITE|VM_SHARED)) == (VM_WRITE|VM_SHARED)
       - it is not a 'special' mapping
          (vm_flags & (VM_PFNMAP|VM_INSERTPAGE)) == 0
       - the backing_dev_info is cap_account_dirty
          mapping_cap_account_dirty(vma->vm_file->f_mapping)
       - f_op->mmap() didn't change the default page protection
      
      Page from remap_pfn_range() are explicitly excluded because their COW
      semantics are already horrid enough (see vm_normal_page() in do_wp_page()) and
      because they don't have a backing store anyway.
      
      mprotect() is taught about the new behaviour as well.  However it overrides
      the last condition.
      
      Cleaning the pages on write-back is done with page_mkclean() a new rmap call.
      It can be called on any page, but is currently only implemented for mapped
      pages, if the page is found the be of a VMA that accounts dirty pages it will
      also wrprotect the PTE.
      
      Finally, in fs/buffers.c:try_to_free_buffers(); remove clear_page_dirty() from
      under ->private_lock.  This seems to be safe, since ->private_lock is used to
      serialize access to the buffers, not the page itself.  This is needed because
      clear_page_dirty() will call into page_mkclean() and would thereby violate
      locking order.

      [PATCH] mm: VM_BUG_ON · 725d704e
      Nick Piggin authored
      
      
      Introduce a VM_BUG_ON, which is turned on with CONFIG_DEBUG_VM.  Use this
      in the lightweight, inline refcounting functions; PageLRU and PageActive
      checks in vmscan, because they're pretty well confined to vmscan.  And in
      page allocate/free fastpaths which can be the hottest parts of the kernel
      for kbuilds.
      
      Unlike BUG_ON, VM_BUG_ON must not be used to execute statements with
      side-effects, and should not be used outside core mm code.

      [PATCH] update to the kernel kmap/kunmap API · a6ca1b99
      James Bottomley authored
      
      
      Give non-highmem architectures access to the kmap API for the purposes of
      overriding (this is what the attached patch does).
      
      The proposal is that we should now require all architectures with coherence
      issues to manage data coherence via the kmap/kunmap API.  Thus driver
      writers never have to write code like
      
          kmap(page)
          modify data in page
          flush_kernel_dcache_page(page)
          kunmap(page)
      
      instead, kmap/kunmap will manage the coherence and driver (and filesystem)
      writers don't need to worry about how to flush between kmap and kunmap.
      
      For most architectures, the page only needs to be flushed if it was
      actually written to *and* there are user mappings of it, so the best
      implementation looks to be: clear the page dirty pte bit in the kernel page
      tables on kmap and on kunmap, check page->mappings for user maps, and then
      the dirty bit, and only flush if it both has user mappings and is dirty.

      [PATCH] jbd: fix commit of ordered data buffers · 3998b930
      Jan Kara authored
      
      
      Original commit code assumes, that when a buffer on BJ_SyncData list is
      locked, it is being written to disk.  But this is not true and hence it can
      lead to a potential data loss on crash.  Also the code didn't count with
      the fact that journal_dirty_data() can steal buffers from committing
      transaction and hence could write buffers that no longer belong to the
      committing transaction.  Finally it could possibly happen that we tried
      writing out one buffer several times.
      
      The patch below tries to solve these problems by a complete rewrite of the
      data commit code.  We go through buffers on t_sync_datalist, lock buffers
      needing write out and store them in an array.  Buffers are also immediately
      refiled to BJ_Locked list or unfiled (if the write out is completed).  When
      the array is full or we have to block on buffer lock, we submit all
      accumulated buffers for IO.

      [PATCH] Fix longstanding load balancing bug in the scheduler · 0a2966b4
      Christoph Lameter authored
      The scheduler will stop load balancing if the most busy processor contains
      processes pinned via processor affinity.
      
      The scheduler currently only does one search for busiest cpu.  If it cannot
      pull any tasks away from the busiest cpu because they were pinned then the
      scheduler goes into a corner and sulks leaving the idle processors idle.
      
      F.e.  If you have processor 0 busy running four tasks pinned via taskset,
      there are none on processor 1 and one just started two processes on
      processor 2 then the scheduler will not move one of the two processes away
      from processor 2.
      
      This patch fixes that issue by forcing the scheduler to come out of its
      corner and retrying the load balancing by considering other processors for
      load balancing.
      
      This patch was originally developed by John Hawkes and discussed at
      
          http://marc.theaimsgroup.com/?l=linux-kernel&m=113901368523205&w=2
      
      .
      
      I have removed extraneous material and gone back to equipping struct rq
      with the cpu the queue is associated with since this makes the patch much
      easier and it is likely that others in the future will have the same
      difficulty of figuring out which processor owns which runqueue.
      
      The overhead added through these patches is a single word on the stack if
      the kernel is configured to support 32 cpus or less (32 bit).  For 32 bit
      environments the maximum number of cpus that can be configued is 255 which
      would result in the use of 32 bytes additional on the stack.  On IA64 up to
      1k cpus can be configured which will result in the use of 128 additional
      bytes on the stack.  The maximum additional cache footprint is one
      cacheline.  Typically memory use will be much less than a cacheline and the
      additional cpumask will be placed on the stack in a cacheline that already
      contains other local variable.

      [PATCH] VIDIOC_ENUMSTD bug · b7de567b
      Jonathan Corbet authored
      
      
      The v4l2 API documentation for VIDIOC_ENUMSTD says:
      
      	To enumerate all standards applications shall begin at index
      	zero, incrementing by one until the driver returns EINVAL.
      
      The actual code, however, tests the index this way:
      
                     if (index<=0 || index >= vfd->tvnormsize) {
                              ret=-EINVAL;
      
      So any application which passes in index=0 gets EINVAL right off the bat
      - and, in fact, this is what happens to mplayer.  So I think the
      following patch is called for, and maybe even appropriate for a 2.6.18.x
      stable release.

      Invoking load_module() before param_sysfs_init() is called crashes in
      mod_sysfs_setup(), since the kset in module_subsys is not initialized yet.
      
      In my case, net-pf-1 is getting modprobed as a result of hotplug trying to
      create a UNIX socket.  Calls to hotplug begin after the topology_init
      initcall.
      
      Another patch for the same symptom (module_subsys-initialize-earlier.patch)
      moves param_sysfs_init() to the subsys initcalls, but this is still not
      early enough in the boot process in some cases.  In particular,
      topology_init() causes /sbin/hotplug to run, which requests net-pf-1 (the
      UNIX socket protocol) which can be compiled as a module.  Moving
      param_sysfs_init() to the postcore initcalls fixes this particular race,
      but there might well be other cases where a usermodehelper causes a module
      to load earlier still.
      
      The patch makes load_module() return an error rather than crashing the
      kernel if invoked before module_subsys is initialized.

      [PATCH] i386: fix flat mode numa on a real numa system · bfa0e9a0

      If there is only 1 node in the system cpus should think they are apart of
      some other node.
      
      If cases where a real numa system boots the Flat numa option make sure the
      cpus don't claim to be apart on a non-existent node.

      [PATCH] cpu to node relationship fixup: map cpu to node · 3212fe15
      KAMEZAWA Hiroyuki authored
      
      
      Assume that a cpu is *physically* offlined at boot time...
      
      Because smpboot.c::smp_boot_cpu_map() canoot find cpu's sapicid,
      numa.c::build_cpu_to_node_map() cannot build cpu<->node map for
      offlined cpu.
      
      For such cpus, cpu_to_node map should be fixed at cpu-hot-add.
      This mapping should be done before cpu onlining.
      
      This patch also handles cpu hotremove case.

      [PATCH] cpu to node relationship fixup: acpi_map_cpu2node · 08992986
      KAMEZAWA Hiroyuki authored
      
      
      Problem description:
      
        We have additional_cpus= option for allocating possible_cpus.  But nid
        for possible cpus are not fixed at boot time.  cpus which is offlined at
        boot or cpus which is not on SRAT is not tied to its node.  This will
        cause panic at cpu onlining.
      
      Usually, pxm_to_nid() mapping is fixed at boot time by SRAT.
      
      But, unfortunately, some system (my system!) do not include
      full SRAT table for possible cpus.  (Then, I use
      additiona_cpus= option.)
      
      For such possible cpus, pxm<->nid should be fixed at
      hot-add.  We now have acpi_map_pxm_to_node() which is also
      used at boot.  It's suitable here.

      [PATCH] i386 bootioremap / kexec fix · 24fd425e

      With CONFIG_PHYSICAL_START set to a non default values the i386
      boot_ioremap code calculated its pte index wrong and users of boot_ioremap
      have their areas incorrectly mapped (for me SRAT table not mapped during
      early boot).  This patch removes the addr < BOOT_PTE_PTRS constraint.

      [PATCH] autofs4: zero timeout prevents shutdown · c0ba7e51
      Ian Kent authored
      
      
      If the timeout of an autofs mount is set to zero then umounts are disabled.
       This works fine, however the kernel module checks the expire timeout and
      goes no further if it is zero.  This is not the right thing to do at
      shutdown as the module is passed an option to expire mounts regardless of
      their timeout setting.
      
      This patch allows autofs to honor the force expire option.
