       "The device tree conversion for arm/ux500 in 3.5 turns out to be
        incomplete because of a mismerge done by Linus Walleij that I failed
        to notice early enough and that Lee Jones as the original author of
        those patches did not manage to fix during the -next cycle.  While we
        originally to get a much larger set of ux500 device tree enablement
        patches merged, this did not happen in time.
      
        After some discussion at Linaro Connect conference this week, Lee has
        been able to do damage control and provide a series to put the broken
        platform back into usable shape for both DT and non-DT based booting.
      
        This series has not been part of linux-next and is based on top of the
        current state of the upstream kernel rather than an -rc, but this is
        the best we could manage given the earlier breakage."

      Since commit 6a918bad, the mxc_nand driver
      fails with:
      
      Driver must set ecc.strength when using hardware ECC
      
      This is because nand_scan_tail checks for correct ecc strength
      settings, so we must set them up before nand_scan_tail.

      mtd: block2mtd: fix recursive call of mtd_writev · 2e24e32e
      Gabor Juhos authored
      The 'mtd_writev' interface calls the function assigned
      to the '_write' field of a given mtd device if that is
      not NULL. The block2mtd driver sets the '_writev' field
      to the 'mtd_writev' function itself and thus causes a
      endless loop.
      
      This is caused by 1dbebd32
      (mtd: harmonize mtd_writev usage).
      
      Remove the assignment from the block2mtd driver to fix the
      issue.

      x86: get rid of calling do_notify_resume() when returning to kernel mode · 44fbbb3d
      Al Viro authored
      If we end up calling do_notify_resume() with !user_mode(refs), it
      does nothing (do_signal() explicitly bails out and we can't get there
      with TIF_NOTIFY_RESUME in such situations).  Then we jump to
      resume_userspace_sig, which rechecks the same thing and bails out
      to resume_kernel, thus breaking the loop.
      
      It's easier and cheaper to check *before* calling do_notify_resume()
      and bail out to resume_kernel immediately.  And kill the check in
      do_signal()...
      
      Note that on amd64 we can't get there with !user_mode() at all - asm
      glue takes care of that.

      new helper: signal_delivered() · efee984c

      Does block_sigmask() + tracehook_signal_handler();  called when
      sigframe has been successfully built.  All architectures converted
      to it; block_sigmask() itself is gone now (merged into this one).
      
      I'm still not too happy with the signature, but that's a separate
      story (IMO we need a structure that would contain signal number +
      siginfo + k_sigaction, so that get_signal_to_deliver() would fill one,
      signal_delivered(), handle_signal() and probably setup...frame() -
      take one).

      nfs: don't open in ->d_revalidate · 0ef97dcf
      Miklos Szeredi authored
      NFSv4 can't do reliable opens in d_revalidate, since it cannot know whether a
      mount needs to be followed or not.  It does check d_mountpoint() on the dentry,
      which can result in a weird error if the VFS found that the mount does not in
      fact need to be followed, e.g.:
      
        # mount --bind /mnt/nfs /mnt/nfs-clone
        # echo something > /mnt/nfs/tmp/bar
        # echo x > /tmp/file
        # mount --bind /tmp/file /mnt/nfs-clone/tmp/bar
        # cat  /mnt/nfs/tmp/bar
        cat: /mnt/nfs/tmp/bar: Not a directory
      
      Which should, by any sane filesystem, result in "something" being printed.
      
      So instead do the open in f_op->open() and in the unlikely case that the cached
      dentry turned out to be invalid, drop the dentry and return EOPENSTALE to let
      the VFS retry.

      vfs: retry last component if opening stale dentry · 16b1c1cd
      Miklos Szeredi authored
      NFS optimizes away d_revalidates for last component of open.  This means that
      open itself can find the dentry stale.
      
      This patch allows the filesystem to return EOPENSTALE and the VFS will retry the
      lookup on just the last component if possible.
      
      If the lookup was done using RCU mode, including the last component, then this
      is not possible since the parent dentry is lost.  In this case fall back to
      non-RCU lookup.  Currently this is not used since NFS will always leave RCU
      mode.
