commit 210787e82a upstream.
On il3945_down procedure we free tx queue data and nullify il->txq
pointer. After that we drop mutex and then cancel delayed works. There
is possibility, that after drooping mutex and before the cancel, some
delayed work will start and crash while trying to send commands to
the device. For example, here is reported crash in
il3945_bg_reg_txpower_periodic():
https://bugzilla.kernel.org/show_bug.cgi?id=42766#c10
Patch fix problem by adding il->txq check on works that send commands,
hence utilize tx queue.

commit 8ee161ce5e upstream.
When the system is under heavy load, there can be a significant delay
between the getscl() and time_after() calls inside sclhi(). That delay
may cause the time_after() check to trigger after SCL has gone high,
causing sclhi() to return -ETIMEDOUT.
To fix the problem, double check that SCL is still low after the
timeout has been reached, before deciding to return -ETIMEDOUT.

commit ff3bc1e752 upstream.
When pre-allocating skbs for received packets, we set ip_summed =
CHECKSUM_UNNCESSARY. We used to change it back to CHECKSUM_NONE when
the received packet had an incorrect checksum or unhandled protocol.
Commit bc8acf2c8c ('drivers/net: avoid
some skb->ip_summed initializations') mistakenly replaced the latter
assignment with a DEBUG-only assertion that ip_summed ==
CHECKSUM_NONE. This assertion is always false, but it seems no-one
has exercised this code path in a DEBUG build.
Fix this by moving our assignment of CHECKSUM_UNNECESSARY into

[ Upstream commit 11aad99af6 ]
This driver attempts to use two TX rings but lacks proper support :
1) IRQ handler only takes care of TX completion on first TX ring
2) the stop/start logic uses the legacy functions (for non multiqueue
drivers)
This means all packets witk skb mark set to 1 are sent through high
queue but are never cleaned and queue eventualy fills and block the
device, triggering the infamous "NETDEV WATCHDOG" message.
Lets use a single TX ring to fix the problem, this driver is not a real
multiqueue one yet.
Minimal fix for stable kernels.

[ Upstream commit 8a49ad6e89 ]
This patch fixes a (mostly cosmetic) bug introduced by the patch
'ppp: Use SKB queue abstraction interfaces in fragment processing'
found here: http://www.spinics.net/lists/netdev/msg153312.html
The above patch rewrote and moved the code responsible for cleaning
up discarded fragments but the new code does not catch every case
where this is necessary. This results in some discarded fragments
remaining in the queue, and triggering a 'bad seq' error on the
subsequent call to ppp_mp_reconstruct. Fragments are discarded
whenever other fragments of the same frame have been lost.
This can generate a lot of unwanted and misleading log messages.
This patch also adds additional detail to the debug logging to
make it clearer which fragments were lost and which other fragments
were discarded as a result of losses. (Run pppd with 'kdebug 1'
option to enable debug logging.)

commit 3780d038fd upstream.
Is possible that we stop queue and then do not wake up it again,
especially when packets are transmitted fast. That can be easily
reproduced with modified tx queue entry_num to some small value e.g. 16.
If mac80211 already hold local->queue_stop_reason_lock, then we can wait
on that lock in both rt2x00queue_pause_queue() and
rt2x00queue_unpause_queue(). After drooping ->queue_stop_reason_lock
is possible that __ieee80211_wake_queue() will be performed before
__ieee80211_stop_queue(), hence we stop queue and newer wake up it
again.
Another race condition is possible when between rt2x00queue_threshold()
check and rt2x00queue_pause_queue() we will process all pending tx
buffers on different cpu. This might happen if for example interrupt
will be triggered on cpu performing rt2x00mac_tx().
To prevent race conditions serialize pause/unpause by queue->tx_lock.

commit fe6b91f470 upstream.
Disabling all runtime PM during system shutdown turns out not to be a
good idea, because some devices may need to be woken up from a
low-power state at that time.
The whole point of disabling runtime PM for system shutdown was to
prevent untimely runtime-suspend method calls. This patch (as1504)
accomplishes the same result by incrementing the usage count for each
device and waiting for ongoing runtime-PM callbacks to finish. This
is what we already do during system suspend and hibernation, which
makes sense since the shutdown method is pretty much a legacy analog
of the pm->poweroff method.
This fixes a recent regression on some OMAP systems introduced by
commit af8db1508f (PM / driver core:
disable device's runtime PM during shutdown).

commit aaff12039f upstream.
Some older Panasonic made camcorders (Panasonic AG-EZ30 and NV-DX110,
Grundig Scenos DLC 2000) reject requests with ack_busy_X if a request is
sent immediately after they sent a response to a prior transaction.
This causes firewire-core to fail probing of the camcorder with "giving
up on config rom for node id ...". Consequently, programs like kino or
dvgrab are unaware of the presence of a camcorder.
Such transaction failures happen also with the ieee1394 driver stack
(of the 2.4...2.6 kernel series until 2.6.36 inclusive) but with a lower
likelihood, such that kino or dvgrab are generally able to use these
camcorders via the older driver stack. The cause for firewire-ohci's or
firewire-core's worse behavior is not yet known. Gap count optimization
in firewire-core is not the cause. Perhaps the slightly higher latency
of transaction completion in the older stack plays a role. (ieee1394:
AR-resp DMA context tasklet -> packet completion ktread -> user process;
firewire-core: tasklet -> user process.)
This change introduces retries and delays after ack_busy_X into
firewire-core's Config ROM reader, such that at least firewire-core's
probing and /dev/fw* creation are successful. This still leaves the
problem that userland processes are facing transaction failures.
gscanbus's built-in retry routines deal with them successfully, but
neither kino's nor dvgrab's do ever succeed.
But at least DV capture with "dvgrab -noavc -card 0" works now. Live
video preview in kino works too, but not actual capture.
One way to prevent Configuration ROM reading failures in application
programs is to modify libraw1394 to synthesize read responses by means
of firewire-core's Configuration ROM cache. This would only leave
CMP and FCP transaction failures as a potential problem source for
applications.

Clemens points out that we need to use compat_ptr() in order to safely

Before, our conversion went wrong
- in practice if the client cast from pointer to integer such that
sign-extension happened, (libraw1394 and libdc1394 at least were not
doing that, IOW were not affected)
or
- in theory on s390 (which doesn't have FireWire though) and on the
tile architecture, regardless of what the client does.
The bug would usually be observed as the initial get_info ioctl failing
with "Bad address" (EFAULT).

commit c49d005b6c upstream.
A hardware bug in the OMAP4 HDMI PHY causes physical damage to the board
if the HDMI PHY is kept powered on when the cable is not connected.
This patch solves the problem by adding hot-plug-detection into the HDMI
IP driver. This is not a real HPD support in the sense that nobody else
than the IP driver gets to know about the HPD events, but is only meant
to fix the HW bug.
The strategy is simple: If the display device is turned off by the user,
the PHY power is set to OFF. When the display device is turned on by the
user, the PHY power is set either to LDOON or TXON, depending on whether
the HDMI cable is connected.
The reason to avoid PHY OFF when the display device is on, but the cable
is disconnected, is that when the PHY is turned OFF, the HDMI IP is not
"ticking" and thus the DISPC does not receive pixel clock from the HDMI
IP. This would, for example, prevent any VSYNCs from happening, and
would thus affect the users of omapdss. By using LDOON when the cable is
disconnected we'll avoid the HW bug, but keep the HDMI working as usual
from the user's point of view.

and was able to mkfs an exofs filesystem and access osds
from user-mode.
All the open-osd user-mode code uses the same library
to access devices through their symbolic names in
/dev/osdX so I'd say it's pretty safe. (Well tested)
