      From: Zwane Mwaikambo <zwane@arm.linux.org.uk>
      
      A kernel janitor recently got confused by the advice in SubmittingPatches
      and was sending patches with the wrong strip level, i think just about
      everyone would prefer standard patches.  Also mention various patch
      management scripts for batching up large deltas.

      [PATCH] Set module license in mcheck/non-fatal.c · 65782400
      Andrew Morton authored
      From: Herbert Xu <herbert@gondor.apana.org.au>
      
      This patch sets the module license for mcheck/non-fatal.c.  The module
      doesn't work at all without this as one of the symbols it needs is only
      exported as GPL.

      [PATCH] remove Documentation/DocBook/parportbook.tmpl · f13fcc31
      Andrew Morton authored
      From: Christoph Hellwig <hch@lst.de>
      
      The partportbook is licensed under the GFDL and Linus agreed to remove
      all GFDL licensed files in
      http://www.ussg.iu.edu/hypermail/linux/kernel/0306.1/1968.html.
      
      I pinged the author the first time on the 2nd of april but still didn't get
      a reply, then send a patch to Linus to remove it last week but linus
      ignored it.  Here's the patch again:

      [PATCH] ISDN Eicon driver: remove call to trap usermode helper · 4a99dc71
      Andrew Morton authored
      From: Armin Schindler <armin@melware.de>
      
      This patch removes the function to call a usermode helper if the hardware
      and its firmware has a problem.  This feature is already implemented in the
      user utility and the driver does not need to care about it.

      [PATCH] slab: use order 0 for vfs caches · 1b2569fb
      Andrew Morton authored
      We have interesting deadlocks when slab decides to use order-1 allocations for
      ext3_inode_cache.  This is because ext3_alloc_inode() needs to perform a
      GFP_NOFS 1-order allocation.
      
      Sometimes the 1-order allocation needs to free a huge number of pages (tens of
      megabytes) before a 1-order grouping becomes available.  But the GFP_NOFS
      allocator cannot free dcache (and hence icache) due to the deadlock problems
      identified in shrink_dcache_memory().
      
      So change slab so that it will force 0-order allocations for shrinkable VFS
      objects.  We can handle those OK.

      Patch below fixes three small bugs in efivars.c as posted by Matt Tolentino
      last week and included in the latest -mm.  Aside from this small patch, I'm
      quite pleased with Matt T's work, thanks!
      
      - dummy() used for reading write-only sysfs files should return -ENODEV to
        indicate failure, not 0.
      
      - efivar_create() should return the number of bytes written on success, not
        zero.
      
      - efivar_delete() should return the number of bytes written on success, not
        zero.

      [PATCH] efivars: remove from arch/ia64 · 855647c4
      Andrew Morton authored
      From: Matt Tolentino <metolent@snoqualmie.dp.intel.com>
      
      I broke up the efivars driver update patch I had sent out quite a while ago
      into several smaller patches.  This includes several fixes and suggestions
      that were pointed out.  The patches are broken down as follows:
      
      1 - remove all traces of efivars from arch/ia64/
      2 - add new sysfs based efivars driver into
          drivers/firmware with accompanying Kconfig/Makefile
          changes to make it fully functional for ia64 again.
      3 - cleans up x86 references to the /proc version of
          the efivars driver.

      [PATCH] slab alignment fixes · afcd93a4
      Andrew Morton authored
      From: Manfred Spraul <manfred@colorfullife.com>
      
      Below is a patch that redefines the kmem_cache_alloc `align' argument:
      
      - align not zero: use the specified alignment.  I think values smaller than
        sizeof(void*) will work, even on archs with strict alignment requirement (or
        at least: slab shouldn't crash.  Obviously the user must handle the
        alignment properly).
      
      - align zero:
      * debug on: align to sizeof(void*)
      * debug off, SLAB_HWCACHE_ALIGN clear: align to sizeof(void*)
      * debug off, SLAB_HWCACHE_ALIGN set: align to the smaller of
         - cache_line_size()
         - the object size, rounded up to the next power of two.
        Slab never honored cache align for tiny objects: otherwise the 32-byte
        kmalloc objects would use 128 byte objects.
      
      There is one additional point: right now slab uses ints for the bufctls.
      Using short would save two bytes for each object.  Initially I had used short,
      but davem objected.  IIRC because some archs do not handle short efficiently. 
      Should I allow arch overrides for the bufctls?  On i386, saving two bytes
      might allow a few additional anon_vma objects in each page.

      [PATCH] ppc64: Move Initrd · e51a23c6
      Andrew Morton authored
      From: Rusty Russell <rusty@rustcorp.com.au>
      
      This patch moves the initrd when "make_room" runs out of space, rather than
      stepping over it.  The problem with stepping over it is that it gets copied
      with the kernel when this happens, which wastes space.
      
      Also ensures that the initrd isn't where the kernel wants to be moved to: if
      it is, it gets moved out the way.

      [PATCH] ppc64: Initrd Cleanup · 54c832af

      Clean up initrd handling.
      
      1) Expose initrd_start and initrd_end to prom.c (replacing its local
         initrd_start and initrd_len).
      
      2) Don't hand mem (aka klimit) through functions which don't need it.
      
      3) Add more debugging under DEBUG_PROM in case we broke anything.

      [PATCH] ppc64: make_room macro for ppc64 prom.c · efa8a179
      Andrew Morton authored
      From: Rusty Russell <rusty@rustcorp.com.au>
      
      copy_device_tree calls inspect_node() which recurses to copy the Open Firmware
      device tree.  It just copied into memory above the kernel for about 8MB, which
      can overwrite the initrd, and/or get truncated on big machines.
      
      The real solution is to allocate memory properly for all the prom_init memory
      users.  However, that's quite a change.  This patch introduces a "make_room"
      macro which inspect_node uses to get memory.  This does the same as before,
      except skips over the initrd if neccessary.

      [PATCH] ppc64: Make finish_device_tree use lmb_alloc, not klimit · d6d33678
      Andrew Morton authored
      From: Rusty Russell <rusty@rustcorp.com.au>
      
      finish_device_tree simply allocates nodes by incrementing klimit (ie.  using
      memory on top of the kernel).  Change it to figure out how much memory it
      needs, then use lmb_alloc to allocate that, then fill it in.
      
      This gets rid of the only manipulation of klimit after prom_init.
