    I think the problem comes from "markers: fix duplicate modpost entry"
    (commit d35cb36)
    
    Especially :
    
      -   add_marker(mod, marker, fmt);
      +   if (!mod->skip)
      +     add_marker(mod, marker, fmt);
        }
        return;
       fail:
    
    Here is a fix that should take care if this problem.
    
    Thanks for the bug report!

  8. atmel-mci: Initialize BLKR before sending data transfer command

    The atmel-mci driver sometimes fails data transfers like this:
    
       mmcblk0: error -5 transferring data
       end_request: I/O error, dev mmcblk0, sector 2749769
       end_request: I/O error, dev mmcblk0, sector 2749777
    
    It turns out that this might be caused by the BLKR register (which
    contains the block size and the number of blocks being transfered) being
    initialized too late. This patch moves the initialization of BLKR so
    that it contains the correct value before the block transfer command is
    sent.
    
    This error is difficult to reproduce, but if you insert a long delay
    (mdelay(10) or thereabouts) between the calls to atmci_start_command()
    and atmci_submit_data(), all transfers seem to fail without this patch,
    while I haven't seen any failures with this patch.

    kgdb, x86: Avoid invoking kgdb_nmicallback twice per NMI

    Stress-testing KVM's latest NMI support with kgdbts inside an SMP guest,
    I came across spurious unhandled NMIs while running the singlestep test.
    Looking closer at the code path each NMI takes when KGDB is enabled, I
    noticed that kgdb_nmicallback is called twice per event: One time via
    DIE_NMI_IPI notification, the second time on DIE_NMI. Removing the first
    invocation cures the unhandled NMIs here.

    x86 ACPI: Blacklist two HP machines with buggy BIOSes

    There is a bug in the BIOSes of some HP boxes with AMD Turions which
    connects IO-APIC pins with ACPI thermal trip points in such a way that
    if the state of the IO-APIC is not as expected by the (buggy) BIOS, the
    thermal trip points are set to insanely low values (usually all of them
    become 16 degrees Celsius).  As a result, thermal throttling kicks in
    and knock the system down to its shoes.
    
    Unfortunately some of the recent IO-APIC changes made the bug show up.
    To prevent this from happening, blacklist machines that are known to be
    affected (nx6115 and 6715b in this particular case).
    
    This fixes http://bugzilla.kernel.org/show_bug.cgi?id=11516 listed as
    a regression from 2.6.26.
    
    On my box it was caused by:
    
    commit 691874f
    Author: Maciej W. Rozycki <macro@linux-mips.org>
    Date:   Tue May 27 21:19:51 2008 +0100

    and the whole story is described in this (huge) thread:
    
        http://marc.info/?l=linux-kernel&m=121358440508410&w=4
    
    Matthew Garrett told us about that happening on the nx6125:
    
        http://marc.info/?l=linux-kernel&m=121396307411930&w=4
    
    and then Maciej analysed the breakage on the basis of a DSDT from the
    nx6325:
    
        http://marc.info/?l=linux-kernel&m=121401068718826&w=4
    
    As far as the Dmitry's and Jason's boxes are concerned, I recognized the
    symptoms and asked them to verify that the blacklisting helped.
    
    It appears that the buggy BIOS code has been copy-pasted to the entire
    range of machines, for no good reason.

  3. IDE: Fix platform device registration in Swarm IDE driver (v2)

    The Swarm IDE driver uses a release method which is defined in the driver
    itself thus potentially oopsable.  The simple fix would be to just leak
    the device but this patch goes the full length and moves the entire
    handling of the platform device in the platform code and retains only
    the platform driver code in drivers/ide/mips/swarm.c.

    This is probably never hit anyway -- with the DMA buffers aligned to at least

    This build breakage is caused by some header file shuffle in linux-next.  But
    I suggest that this patch be merged ahead of linux-next to avoid bisection
    breakage.

  22. V4L/DVB (8958): zr36067: Return proper bytes-per-line value

    The zr36067 driver should return the actual bytes-per-line value when
    queried with ioctl VIDIOC_G_FMT, instead of 0. Otherwise user-space
    applications can get confused.
    
    Likewise, with ioctl VIDIOC_S_FMT, we are supposed to fill the
    bytes-per-line value. And we shouldn't fail if the caller sets the
    initial value to something different from 0. This is perfectly valid
    for applications to pre-fill this field with the value they expect.
