      Pull GFS2 updates from Steven Whitehouse:
       "The main feature this time is the new Orlov allocator and the patches
        leading up to it which allow us to allocate new inodes from their own
        allocation context, rather than borrowing that of their parent
        directory.  It is this change which then allows us to choose a
        different location for subdirectories when required.  This works
        exactly as per the ext3 implementation from the users point of view.
      
        In addition to that, we've got a speed up in gfs2_rbm_from_block()
        from Bob Peterson, three locking related improvements from Dave
        Teigland plus a selection of smaller bug fixes and clean ups."

      Linus Torvalds authored
      This reverts commit 53b87cf0.
      
      It causes odd bootup problems on x86-64.  Markus Trippelsdorf gets a
      repeatable oops, and I see a non-repeatable oops (or constant stream of
      messages that scroll off too quickly to read) that seems to go away with
      this commit reverted.
      
      So we don't know exactly what is wrong with the commit, but it's
      definitely problematic, and worth reverting sooner rather than later.

      Pull x86 ACPI update from Peter Anvin:
       "This is a patchset which didn't make the last merge window.  It adds a
        debugging capability to feed ACPI tables via the initramfs.
      
        On a grander scope, it formalizes using the initramfs protocol for
        feeding arbitrary blobs which need to be accessed early to the kernel:
        they are fed first in the initramfs blob (lots of bootloaders can
        concatenate this at boot time, others can use a single file) in an
        uncompressed cpio archive using filenames starting with "kernel/".
      
        The ACPI maintainers requested that this patchset be fed via the x86
        tree rather than the ACPI tree as the footprint in the general x86
        code is much bigger than in the ACPI code proper."

      Linus Torvalds authored
      This reverts commit f269ae04.
      
      It turns out it causes a very noticeable interactivity regression with
      CONFIG_SCHED_AUTOGROUP (test-case: "make -j32" of the kernel in a
      terminal window, while scrolling in a browser - the autogrouping means
      that the two end up in separate cgroups, and the browser should be
      smooth as silk despite the high load).
      
      Says Paul Turner:
       "It seems that the update-throttling on the wake-side is reducing the
        interactive tasks' ability to preempt.  While I suspect the right
        longer term answer here is force these updates only in the
        cross-cgroup case; this is less trivial.  For this release I believe
        the right answer is either going to be a revert or restore the updates
        on the enqueue-side."

        A NACK is probably the right thing. I was mostly converting a few
        other drivers which used some simple, common patterns to use my new
        common code, but this driver was missing it altogether. It looks like
        there may be bigger issues, though, as you point out.

        As noted earlier, I don't have much interest in this driver. I agree
        that there are some other issues with the driver; I think it leaks
        memory if it is ever allowed to unload, for one. Feel free to submit
        an alternative patch to prevent this driver from being built as a
        module.
