that's the right thing to do there is a separate question, but

30037818f7 advansys fix on ISA-less configs
The code

        if (shost->dma_channel != NO_ISA_DMA)
                free_dma(shost->dma_channel);

in there is triggerable only if we have CONFIG_ISA (we only set ->dma_channel to
something other than NO_ISA_DMA under #ifdef CONFIG_ISA).  OTOH, free_dma() is
not guaranteed to be there in absense of CONFIG_ISA.  IOW, driver runs into
undefined symbols on PCI-but-not-ISA configs (e.g. on frv) and it's a false
positive.

Fix: put the entire if () under #ifdef CONFIG_ISA; behaviour doesn't change and
dependency on free_dma() disappears for !CONFIG_ISA.

9a5aa622dd mlx4_core: Save/restore default port IB capability mask
Commit 7ff93f8b ("mlx4_core: Multiple port type support") introduced
support for different port types.  As part of that support, SET_PORT
is invoked to set the port type during driver startup.  However, as a
side-effect, for IB ports the invocation of this command also sets the
port's capability mask to zero (losing the default value set by FW).

To fix this, get the default ib port capabilities (via a MAD_IFC Port
Info query) during driver startup, and save them for use in the
mlx4_SET_PORT command when setting the port-type to Infiniband.

This patch fixes problems with subnet manager (SM) failover such as
<https://bugs.openfabrics.org/show_bug.cgi?id=1183>, which occurred
because the IsTrapSupported bit in the capability mask was zeroed.

23d0a65cf2 toshiba_acpi: close race in toshiba_acpi driver
the toshiba ACPI driver will, in a failure case, free the rfkill state
before stopping the polling timer that would use this state. More interesting,
in the same failure case handling, it calls the exit function, which also
frees the rfkill state, but after stopping the polling.

If the race happens, a NULL pointer is passed to rfkill_force_state()
which then causes a nice dereference.

Fix the race by just not doing the too-early freeing of the rfkill state.

This appears to be the cause of a hot issue on kerneloops.org; while I
have no solid evidence of that this patch will fix the issue, the race
appears rather real.

0081b16202 ACPI: thinkpad-acpi: fix fan sleep/resume path
This fixes a regression from v2.6.27, caused by commit
5814f737e1cd2cfa2893badd62189acae3e1e1fd, "ACPI: thinkpad-acpi:
attempt to preserve fan state on resume".

It is possible for fan_suspend() to fail to properly initialize
fan_control_desired_level as required by fan_resume(), resulting on
the fan always being set to level 7 on resume if the user didn't
touch the fan controller.

In order to get fan sleep/resume handling to work right:

1. Fix the fan_suspend handling of the T43 firmware quirk. If it is
still undefined, we didn't touch the fan yet and that means we have no
business doing it on resume.

2. Store the fan level on its own variable to avoid any possible
issues with hijacking fan_control_desired_level (which isn't supposed
to have anything other than 0-7 in it, anyway).

3. Change the fan_resume code to me more straightforward to understand
(although we DO optimize the boolean logic there, otherwise it looks
disgusting).

4. Add comments to help understand what the code is supposed to be
doing.

5. Change fan_set_level to be less strict about how auto and
full-speed modes are requested.

After commit 540b8bb9c3:

  sony-laptop: fingers off backlight if video.ko is serving this functionality

I can't set brightness on my sony laptop (nothing in /sys/class/backlight).
dmesg says "sony-laptop: Sony: Brightness ignored, must be controlled by ACPI
video driver".

The function acpi_video_backlight_support returns 0 if we should use the
vendor-specific backlight support, while non-0 if the ACPI generic should
be used. Because of this, the check introduced by the said commit appears
reversed.

65df78473f ACPI suspend: Blacklist boxes that require us to set SCI_EN directly on resume
Some Apple boxes evidently require us to set SCI_EN on resume
directly, because if we don't do that, they hung somewhere in the
resume code path.  Moreover, on these boxes it is not sufficient to
use acpi_enable() to turn ACPI on during resume.  All of this is
against the ACPI specification which states that (1) the BIOS is
supposed to return from the S3 sleep state with ACPI enabled
(SCI_EN set) and (2) the SCI_EN bit is owned by the hardware and we
are not supposed to change it.

For this reason, blacklist the affected systems so that the SCI_EN
bit is set during resume on them.

[NOTE: Unconditional setting SCI_EN for all system on resume doesn't
 work, because it makes some other systems crash (that's to be
 expected).  Also, it is not entirely clear right now if all of the
 Apple boxes require this workaround.]

acpi_evaluate_integer() does malloc(..., irqs_disabled() ? GFP_ATOMIC

There's no way to reliably tell if we need GFP_ATOMIC or not from
code, this one for example fails to detect spinlocks held.

b4b6cda229 ath9k: correct expected max RX buffer size
We should only tell the hardware its capable of DMA'ing
to us only what we asked dev_alloc_skb(). Prior to this
it is possible a large RX'd frame could have corrupted
DMA data but for us but we were saved only because we
were previously also pci_map_single()'ing the same large
value. The issue prior to this though was we were unmapping
a smaller amount which the prior DMA patch fixed.

ca0c7e5101 ath9k: Fix SW-IOMMU bounce buffer starvation
This should fix the SW-IOMMU bounce buffer starvation
seen ok kernel.org bugzilla 11811:

http://bugzilla.kernel.org/show_bug.cgi?id=11811

Users on MacBook Pro 3.1/MacBook v2 would see something like:

DMA: Out of SW-IOMMU space for 4224 bytes at device 0000:0b:00.0

Unfortunately its only easy to trigger on MacBook Pro 3.1/MacBook v2
so far so its difficult to debug (even with swiotlb=force).

We were pci_unmap_single()'ing less bytes than what we called
for with pci_map_single() and as such we were starving
the swiotlb from its 64MB amount of bounce buffers. We remain
consistent and now always use sc->rxbufsize for RX. While at
it we update the beacon DMA maps as well to only use the data
portion of the skb, previous to this we were pci_map_single()'ing
more data for beaconing than what we tell the hardware it can use,
therefore pushing more iotlb abuse.

Still not sure why this is so easily triggerable on
MacBook Pro 3.1, it may be the hardware configuration
tends to use more memory > 3GB mark for DMA.

e91af0af86 iwlagn: fix DMA sync
For the RX DMA fix for iwlwifi ("iwlagn: fix RX skb alignment") Luis
pointed out:

> aligned_dma_addr can obviously be > real_dma_addr at this point, what

I asked around, and he's right, there may be platforms that do not allow
passing such such an address to the DMA API functions. This patch
changes it by using the proper dma_sync_single_range_for_cpu API
invented for this purpose.

11c6dd2c72 phylib: Add Vitesse VSC8221 SGMII PHY
PHY is mostly compatible with the existing VSC8244 PHY.  The init sequence
is different and the interrupt mask lacks some bits present in the VSC8244.

Rather than making a copy of the existing VSC234x config_intr function and
change one constant, I modify it to select the interrupt mask based on
which driver is calling it.  This lets it be used by both drivers.

7953031da4 ARM: OMAP: Remove broken LCD driver for SX1
Recently the omap McBSP code was cleaned up to get rid of
direct McBSP register tinkering by the drivers. Looks like
lcd_sx1.c never got converted, and now it breaks builds.

It seems the lcd_sx1.c driver is attempting SPI mode, but
doing it in a different way compared to omap_mcbsp_set_spi_mode().

Remove the broken driver, patches welcome to add it back when
done properly by patching both mcbsp.c and lcd_sx1.c.

6133047aa6 drm/i915: execbuffer pins objects, no need to ensure they're still in the GTT
Before we had the notion of pinning objects, we had a kludge around to make
sure all of the objects were still resident in the GTT before we committed
to executing a batch buffer. We don't need this any longer, and it sticks an
error return in the middle of object domain computations that must be
associated with a subsequent flush/invalidate emmission into the ring.

05eff845a2 drm/i915: Always read pipestat in irq_handler
Because we write pipestat before iir, it's possible that a pipestat
interrupt will occur between the pipestat write and the iir write. This
leaves pipestat with an interrupt status not visible in iir. This may cause
an interrupt flood as we never clear the pipestat event.

cdfbc41f6d drm/i915: Remove IMR masking during interrupt handler, and restart it if needed.
The IMR masking was a technique recommended for avoiding getting stuck with
no interrupts generated again in MSI mode.  It kept new IIR bits from getting
set between the IIR read and the IIR write, which would have otherwise
prevented an MSI from ever getting generated again.  However, this caused a
problem for vblank as the IMR mask would keep the pipe event interrupt from
getting reflected in IIR, even after the IMR mask was brought back down.

Instead, just check the state of IIR after we ack the interrupts we're going
to handle, and restart if we didn't get IIR all the way to zero.

7c46358642 drm/i915: Manage PIPESTAT to control vblank interrupts instead of IMR.
The pipestat fields affect reporting of all vblank-related interrupts, so we
have to reset them during the irq_handler, and while enabling vblank
interrupts.  Otherwise, if a pipe status field had been set to non-zero
before enabling reporting, we would never see an interrupt again.

This patch adds i915_enable_pipestat and i915_disable_pipestat to abstract
out the steps needed to change the reported interrupts.

ml_ff_playback() uses spin_(un)lock_bh. However this function is
called with interrupts disabled from erase_effect() in
drivers/input/ff-core.c:196.

This is not permitted, and will result in a WARN_ON in the bottom
half handling code. This patch changes this function to just use
spin_lock_irqsave() instead, solving the problem and simplifying
the locking logic.

208fbec5be axnet_cs / pcnet_cs: moving PCMCIA_DEVICE_PROD_ID for Netgear FA411
Hi,

after noticing that my Netgear FA411 (PCMCIA-NIC) [1] stopped working with
the release of the 2.6.25 kernel (sidux-version), I checked the
respective driver sources and noticed that the pcnet_cs driver bailed
out with "use axnet_cs instead" for the Netgear FA411, but axnet_cs
doesn't claim this ID.

I compiled a kernel with the PCMCIA-ID for the netgear card moved to
axnet_cs from pcnet_cs which worked. I then contacted sidux-kernel
maintainer Stefan Lippers-Hollmann who turned the info into this patch
and integrated it into the kernel:

<http://svn.berlios.de/svnroot/repos/fullstory/linux-sidux-2.6/trunk/debian/patches/features/2.6.27.4_PCMCIA_move-PCMCIA-ID-for-Netgear-FA411-from-pcnet_cs-to-axnet_cs.patch>

This works for me and AFAIK there were no reports of any breakage for
other devices on sidux-support.

This looks like a trivial patch, but since I have very limited
experience with kernel modifications  I might be woefully wrong there.
But if there are no side effects of this patch, is it possible to get it
into the official kernel?

I can provide more detailed information on the affected hardware if
necessary.

818a557eeb V4L/DVB (9668): em28xx: fix a race condition with hald
Newer versions of hald tries to open it to call QUERYCAP.

Due to the lack of a proper locking, it is possible to open the device
before it finishes initialization.

This patch adds a lock to avoid this risk, and to protect the list of
em28xx devices.

While here, remove the uneeded BKL lock.

To avoid this ping-pong, use, instead a pre-allocated buffer.

Also, be sure that read control URB's also use the buffer, instead of
relying on a stack buffer.

There's a bug in the usbmon binary reader: When using read() to fetch
the packets and a packet's data is partially read, the next read call
will once again return up to len_cap bytes of data. The b_read counter
is not regarded when determining the remaining chunk size.

So, when dumping USB data with "cat /dev/usbmon0 > usbmon.trace" while
reading from a USB storage device and analyzing the dump file
afterwards it will get out of sync after a couple of packets.

b09bc6cbae USB: fix SB700 usb subsystem hang bug
This patch is required for AMD SB700 south bridge revision A12 and A13 to avoid
USB subsystem hang symptom. The USB subsystem hang symptom is observed when the
system has multiple USB devices connected to it. In some cases a USB hub may be
required to observe this symptom.

This patch works around the problem by correcting the internal register setting
that will help by changing the behavior of the internal logic to avoid the
USB subsystem hang issue. The change in the behavior of the logic does not
impact the normal operation of the USB subsystem.

This means if a driver only has a .set_power method then the system will
OOPS on changing mode (and with the console semaphore held so you cannot
easily see the problem).

Fix the problem by ensuring that either callback is valid before use.

393df744e0 pxa2xx_spi: bugfix full duplex dma data corruption
Fixes a data corruption bug in pxa2xx_spi.c when operating in full duplex
mode with DMA and using buffers that overlap.

SPI transmit and receive buffers are allowed to be the same or to overlap.
 However, this driver fails if such overlap is attempted in DMA mode
because it maps the rx and tx buffers in the wrong order.  By mapping
DMA_FROM_DEVICE (read) before DMA_TO_DEVICE (write), it invalidates the
cache before flushing it, thus discarding data which should have been
transmitted.

The patch corrects the order of mapping.  This bug exists in all versions
of pxa2xx_spi.c; similar bugs are in the drivers for two other SPI
controllers (au1500, imx).

A version of this patch has been tested on kernel 2.6.20 using
verification of loopback data with: random transfer length, random
bits-per-word, random positive offsets (both larger and smaller than
transfer length) between the start of the rx and tx buffers, and varying
clock rates.

de339c2aa7 phylib: Fix auto-negotiation restart avoidance
A previous patch, 51e2a3846e, made
genphy_config_aneg() not restart aneg by calling genphy_restart_aneg() if
the advertisement hadn't changed.

But, genphy_restart_aneg() doesn't just restart aneg, it may also *enable*
aneg or un-isolate the PHY from the MII (those functions are controlled by
the same register).  The code to avoid calling genphy_restart_aneg() didn't
consider this.

So, modify genphy_config_aneg() to also check if the PHY needs to have aneg
enabled or be un-isolated before deciding not to restart aneg.

This caused a problem with certain Davicom PHYs, as that driver isolates
the PHY (why?) before calling genphy_config_aneg() and expects the PHY to
be un-isolated by that function.

4018517a1a iwlagn: fix RX skb alignment
So I dug deeper into the DMA problems I had with iwlagn and a kind soul
helped me in that he said something about pci-e alignment and mentioned
the iwl_rx_allocate function to check for crossing 4KB boundaries. Since
there's 8KB A-MPDU support, crossing 4k boundaries didn't seem like
something the device would fail with, but when I looked into the
function for a minute anyway I stumbled over this little gem:

	BUG_ON(rxb->dma_addr & (~DMA_BIT_MASK(36) & 0xff));

Clearly, that is a totally bogus check, one would hope the compiler
removes it entirely. (Think about it)

After fixing it, I obviously ran into it, nothing guarantees the
alignment the way you want it,  because of the way skbs and their
headroom are allocated. I won't explain that here nor double-check that
I'm right, that goes beyond what most of the CC'ed people care about.

So then I came up with the patch below, and so far my system has
survived minutes with 64K pages, when it would previously fail in
seconds. And I haven't seen a single instance of the TX bug either. But
when you see the patch it'll be pretty obvious to you why.

This should fix the following reported kernel bugs:

http://bugzilla.kernel.org/show_bug.cgi?id=11596
http://bugzilla.kernel.org/show_bug.cgi?id=11393
http://bugzilla.kernel.org/show_bug.cgi?id=11983

I haven't checked if there are any elsewhere, but I suppose RHBZ will
have a few instances too...

I'd like to ask anyone who is CC'ed (those are people I know ran into
the bug) to try this patch.

I am convinced that this patch is correct in spirit, but I haven't
understood why, for example, there are so many unmap calls. I'm not
entirely convinced that this is the only bug leading to the TX reply
errors.

8e3bad65a5 mac80211: remove ieee80211_notify_mac
Before ieee80211_notify_mac() was added, it was presented with the
use case of using it to tell mac80211 that the association may
have been lost because the firmware crashed/reset.

Since then, it has also been used by iwlwifi to (slightly) speed
up re-association after resume, a workaround around the fact that
mac80211 has no suspend/resume handling yet. It is also not used
by any other drivers, so clearly it cannot be necessary for "good
enough" suspend/resume.

Unfortunately, the callback suffers from a severe problem: It only
works for station mode. If suspend/resume happens while in IBSS or
any other mode (but station), then the callback is pointless.

Recently, it has created a number of locking issues, first because
it required rtnl locking rather than RCU due to calling sleeping
functions within the critical section, and now because it's called
by iwlwifi from the mac80211 workqueue that may not use the rtnl
because it is flushed under rtnl.
(cf. http://bugzilla.kernel.org/show_bug.cgi?id=12046)

I think, therefore, that we should take a step back, remove it
entirely for now and add the small feature it provided properly.
For suspend and resume we will need to introduce new hooks, and for
the case where the firmware was reset the driver will probably
simply just pretend it has done a suspend/resume cycle to get
mac80211 to reprogram the hardware completely, not just try to
connect to the current AP again in station mode. When doing so, we
will need to take into account locking issues and possibly defer
to schedule_work from within mac80211 for the resume operation,
while the suspend operation must be done directly.

Proper suspend/resume should also not necessarily try to reconnect
to the current AP, the time spent in suspend may have been short
enough to not be disconnected from the AP, mac80211 will detect
that the AP went out of range quickly if it did, and if the
association is lost then the AP will disassoc as soon as a data

26a3e99160 xen: fix scrub_page()
Impact: fix guest kernel crash with CONFIG_XEN_SCRUB_PAGES=y

Jens noticed that scrub_page() has a buggy unmap of the wrong
thing. (virtual address instead of page)

Linus pointed out that the whole scrub_page() code is an unnecessary
reimplementation of clear_highpage() to begin with.

Just use clear_highpage() rather than reimplementing it poorly.

It is not safe to assume that the i2c gate will be open before issuing the
command to power down the tuner.  In fact, many demods only open the gate
long enough to issue the tuning command.

This fix allows power management to work properly for those tuners behind an
i2c gate (in my case the problem was with the HVR-950Q)

df81d2371a [SCSI] dpt_i2o: fix transferred data length for scsi_set_resid()
dpt_i2o.c::adpt_i2o_to_scsi() reads the value at (reply+5) which
should contain the length in bytes of the transferred data. This
would be correct if reply was a u32 *. However it is a void * here,
so we need to read the value at (reply+20) instead.

The value at (reply+5) is usually 0xff0000, which is apparently
'large enough' and didn't cause any trouble until 2.6.27 where

6a6b97d360 libata: improve phantom device detection
Currently libata uses four methods to detect device presence.

1. PHY status if available.
2. TF register R/W test (only promotes presence, never demotes)
3. device signature after reset
4. IDENTIFY failure detection in SFF state machine

Combination of the above works well in most cases but recently there
have been a few reports where a phantom device causes unnecessary
delay during probe.  In both cases, PHY status wasn't available.  In
one case, it passed #2 and #3 and failed IDENTIFY with ATA_ERR which
didn't qualify as #4.  The other failed #2 but as it passed #3 and #4,
it still caused failure.

In both cases, phantom device reported diagnostic failure, so these
cases can be safely worked around by considering any !ATA_DRQ IDENTIFY
failure as NODEV_HINT if diagnostic failure is set.

3e44017b58 phylib: fix premature freeing of struct mii_bus
Commit 46abc02175 ("phylib: give mdio
buses a device tree presence") added a call to device_unregister() in
a situation where the caller did not intend for the device to be
freed yet, but apart from just unregistering the device from the
system, device_unregister() does an additional put_device() that is
intended to free it.

The right function to use in this situation is device_del(), which
unregisters the device from the system like device_unregister() does,
but without dropping the reference count an additional time.

Bug report from Bryan Wu <cooloney@kernel.org>.
