      [PATCH] inotify/idr leak fix · 8d3b3591
      Andrew Morton 提交于
      Fix a bug which was reported and diagnosed by
      Stefan Jones <stefan.jones@churchillrandoms.co.uk>
      
      IDR trees include a cache of idr_layer objects.  There's no way to destroy
      this cache, so when we discard an overall idr tree we end up leaking some
      memory.
      
      Add and use idr_destroy() for this.  v9fs and infiniband also need to use
      idr_destroy() to avoid leaks.
      
      Or, we make the cache global, like radix_tree_preload().  Which is probably
      better.  Later.

      [PATCH] swiotlb: make sure initial DMA allocations really are in DMA memory · 281dd25c
      Yasunori Goto 提交于
      This introduces a limit parameter to the core bootmem allocator; The new
      parameter indicates that physical memory allocated by the bootmem
      allocator should be within the requested limit.
      
      We also introduce alloc_bootmem_low_pages_limit, alloc_bootmem_node_limit,
      alloc_bootmem_low_pages_node_limit apis, but alloc_bootmem_low_pages_limit
      is the only api used for swiotlb.
      
      The existing alloc_bootmem_low_pages() api could instead have been
      changed and made to pass right limit to the core allocator.  But that
      would make the patch more intrusive for 2.6.14, as other arches use
      alloc_bootmem_low_pages().  We may be done that post 2.6.14 as a
      cleanup.
      
      With this, swiotlb gets memory within 4G for both x86_64 and ia64
      arches.

      [PATCH] Handle spurious page fault for hugetlb region · 3359b54c
      Seth, Rohit 提交于
      The hugetlb pages are currently pre-faulted.  At the time of mmap of
      hugepages, we populate the new PTEs.  It is possible that HW has already
      cached some of the unused PTEs internally.  These stale entries never
      get a chance to be purged in existing control flow.
      
      This patch extends the check in page fault code for hugepages.  Check if
      a faulted address falls with in size for the hugetlb file backing it.
      We return VM_FAULT_MINOR for these cases (assuming that the arch
      specific page-faulting code purges the stale entry for the archs that
      need it).

      [ This is apparently arguably an ia64 port bug. But the code won't
        hurt, and for now it fixes a real problem on some ia64 machines ]
