a477e4e6d4 ath9k: fix oops on trying to hold the wrong spinlock
We were trying to hold the wrong spinlock due to a typo
on IEEE80211_BAR_CTL_TID_S's definition. We use this to
compute the tid number and then hold this this tid number's
spinlock.

Since IPVS now has partial IPv6 support, this patch moves IPVS from

e683b42300 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.

e85ceae910 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.

6252352d16 pkt_sched: Simplify dev_requeue_skb and dequeue_skb
qdisc->requeue was planned to universally replace all requeuing code,
but at the top level we never requeue more than one skb, so qdisc->
gso_skb is enough for this. qdisc->requeue would be used on the lower
levels only for one level deep requeuing (like in sch_hfsc) after
finishing all the changes.

e84956f92a 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:

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.

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

fe6c700ff3 V4L/DVB (9053): fix buffer overflow in uvc-video
There is a buffer overflow in drivers/media/video/uvc/uvc_ctrl.c:

INFO: 0xf2c5ce08-0xf2c5ce0b. First byte 0xa1 instead of 0xcc
INFO: Allocated in uvc_query_v4l2_ctrl+0x3c/0x239 [uvcvideo] age=13 cpu=1 pid=4975
...

A fixed size 8-byte buffer is allocated, and a variable size field is read
into it; there is no particular bound on the size of the field (it is
dependent on hardware and configuration) and it can overflow [also
verified by inserting printk's.]

The patch attempts to size the buffer to the correctly.

bda1cda54b V4L/DVB (9043): S5H1420: Fix size of shadow-array to avoid overflow
The array size of 'shadow' still needs to be fixed in order to not overflow when reading register 0x00.

Thanks to Oliver Endriss for pointing that out.

c18c5ffe13 V4L/DVB (9037): Fix support for Hauppauge Nova-S SE
Different backends have different input busses (saa7146, flexcop).
To reflect that a config-option to the s5h1420-driver was added which makes
the output mode selectable.

Furthermore the s5h1420-driver is now doing the same i2c-method as it was done
before adding support for other i2c-users.

This patch needs to go into the current release of the kernel, as this driver
is currently broken.

(Thanks to Eberhard Kaltenhaeuser for helping out to debug this issue.)

dda06a8e46 V4L/DVB (9029): Fix deadlock in demux code
The functions dvb_dmxdev_section_callback, dvb_dmxdev_ts_callback,
dvb_dmx_swfilter_packet, dvb_dmx_swfilter_packets, dvb_dmx_swfilter and
dvb_dmx_swfilter_204 may be called from both interrupt and process
context. Therefore they need to be protected by spin_lock_irqsave()
instead of spin_lock().

This fixes a deadlock discovered by lockdep.
