      slub: Use alloc_pages_exact_node() for page allocation · 6b65aaf3
      Minchan Kim 提交于
      The alloc_slab_page() in SLUB uses alloc_pages() if node is '-1'.  This means
      that node validity check in alloc_pages_node is unnecessary and we can use
      alloc_pages_exact_node() to avoid comparison and branch as commit
      6484eb3e ("page allocator: do not check NUMA node ID when the caller
      knows the node is valid") did for the page allocator.

      slub: Potential stack overflow · bbd7d57b
      Eric Dumazet 提交于
      I discovered that we can overflow stack if CONFIG_SLUB_DEBUG=y and use slabs

      DECLARE_BITMAP(map, page->objects).

      Grant Likely 提交于
      The of_node pointer is now stored directly in struct device, so
      of_match_device() should work with any device, not just struct of_device.

      struct device instead of struct of_device.

      of: Remove duplicate fields from of_platform_driver · 4018294b
      Grant Likely 提交于
      .name, .match_table and .owner are duplicated in both of_platform_driver
      and device_driver.  This patch is a removes the extra copies from struct
      of_platform_driver and converts all users to the device_driver members.
      
      This patch is a pretty mechanical change.  The usage model doesn't change
      and if any drivers have been missed, or if anything has been fixed up
      incorrectly, then it will fail with a compile time error, and the fixup
      will be trivial.  This patch looks big and scary because it touches so
      many files, but it should be pretty safe.
