Newer gcc are being a bit blind here (it's pretty obvious we don't
reach the code path using the array if we haven't initialized the
pointer) but none of that is performance critical so let's just
silence it.

There was a typo, checking for CONFIG_TRACE_IRQFLAG instead of
CONFIG_TRACE_IRQFLAGS causing some useful debug code to not be
built
This in turns causes a build error on BookE 64-bit due to incorrect
semicolons at the end of a couple of macros, so let's fix that too

Looks like we still have issues with pSeries and Cell idle code
vs. the lazy irq state. In fact, the reset fixes that went upstream
are exposing the problem more by causing BUG_ON() to trigger (which
this patch turns into a WARN_ON instead).
We need to be careful when using a variant of low power state that
has the side effect of turning interrupts back on, to properly set
all the SW & lazy state to look as if everything is enabled before
we enter the low power state with MSR:EE off as we will return with
MSR:EE on. If not, we have a discrepancy of state which can cause
things to go very wrong later on.
This patch moves the logic into a helper and uses it from the
pseries and cell idle code. The power4/970 idle code already got
things right (in assembly even !) so I'm not touching it. The power7
"bare metal" idle code is subtly different and correct. Remains PA6T
and some hypervisor based Cell platforms which have questionable
code in there, but they are mostly dead platforms so I'll fix them
when I manage to get final answers from the respective maintainers
about how the low power state actually works on them.

With the variable operated on being of "unsigned long" type,
neither ffs() nor fls() are suitable to use on them, as those
truncate their arguments to 32 bits. Using __ffs() and __fls()
respectively at once eliminates the need to subtract 1 from their
results.
Additionally, with the alignment value subsequently used as a
shift count, it must be enforced to be less than BITS_PER_LONG
(and on 64-bit there's no need for it to be any smaller).

commit db83d136d7f753 (gianfar: Fix missing sock reference when
processing TX time stamps) added a potential sk_wmem_alloc imbalance
If the new skb has a different truesize than old one, we can get a
negative sk_wmem_alloc once new skb is orphaned at TX completion.
Now we no longer early orphan skbs in dev_hard_start_xmit(), this
probably can lead to fatal bugs.

iterator variable
If list_for_each_entry, etc complete a traversal of the list, the iterator
variable ends up pointing to an address at an offset from the list head,
and not a meaningful structure. Thus this value should not be used after
the end of the iterator. There does not seem to be a meaningful value to
provide to netdev_warn. Replace with pr_warn, since pr_err is used
elsewhere.
This problem was found using Coccinelle (http://coccinelle.lip6.fr/).

And this is only called if write_priomap() is called.

namespaces since it has been added. The debugfs support does not handle

were trying to add and to remove the /proc/net/bonding entries from the
wrong network namespace.
Move the bonding /proc registration code into the NETDEV_REGISTER and
NETDEV_UNREGISTER events where the proc registration and unregistration
will always happen at the right time.

For the higher mtu sizes requiring the buffer size greater than 8192,
the buffers are sent or received using multiple dma descriptors/ same
descriptor with option of multi buffer handling.
It was observed during tests that the driver was missing on data
packets during the normal ping operations if the data buffers being used
catered to jumbo frame handling.
The memory barrriers are added in between preparation of dma descriptors
in the jumbo frame handling path to ensure all instructions before
enabling the dma are complete.

It was observed that during multiple reboots nfs hangs. The status of
receive descriptors shows that all the descriptors were in control of
CPU, and none were assigned to DMA.
Also the DMA status register confirmed that the Rx buffer is
unavailable.
This patch adds the fix for the same by adding the memory barriers to
ascertain that the all instructions before enabling the Rx or Tx DMA are
completed which involves the proper setting of the ownership bit in DMA
descriptors.

When we remove a key, we put a key index which was supposed
to tell the fw that we are actually removing the key. But
instead the fw took that index as a valid index and messed
up the SRAM of the device.
This memory corruption on the device mangled the data of
the SCD. The impact on the user is that SCD queue 2 got
stuck after having removed keys.

iwlwifi: always monitor for stuck queues
If we only monitor while associated, the following
can happen:
- we're associated, and the queue stuck check
runs, setting the queue "touch" time to X
- we disassociate, stopping the monitoring,
which leaves the time set to X
- almost 2s later, we associate, and enqueue
a frame
- before the frame is transmitted, we monitor
for stuck queues, and find the time set to
X, although it is now later than X + 2000ms,
so we decide that the queue is stuck and
erroneously restart the device

On rt2x00_dmastart() we increase index specified by Q_INDEX and on
rt2x00_dmadone() we increase index specified by Q_INDEX_DONE. So entries
between Q_INDEX_DONE and Q_INDEX are those we currently process in the
hardware. Entries between Q_INDEX and Q_INDEX_DONE are those we can
submit to the hardware.
According to that fix rt2x00usb_kick_queue(), as we need to submit RX
entries that are not processed by the hardware. It worked before only
for empty queue, otherwise was broken.
Note that for TX queues indexes ordering are ok. We need to kick entries
that have filled skb, but was not submitted to the hardware, i.e.
started from Q_INDEX_DONE and have ENTRY_DATA_PENDING bit set.
From practical standpoint this fixes RX queue stall, usually reproducible
in AP mode, like for example reported here:

If association failed due to internal error (e.g. no

with assoc=true, while we actually reject the association.
This results in the BSSID not being zeroed out.
After passing assoc=false, we no longer have to call
sta_info_destroy_addr() explicitly. While on it, move
the "associated" message after the assoc_success check.

It happens when adding a number of containers with do:
nfct_query(h, NFCT_Q_CREATE, ct);
and most likely one namespace shuts down.
this problem was supposed to be fixed by:
70e9942 netfilter: nf_conntrack: make event callback registration per-netns
Still, it was missing one rcu_access_pointer to check if the callback
is set or not.

This patch completes commit 08406f5 by fixing the following issues, according to
the reference manual:
* MXC_OTG_UCTRL_OPM_BIT disables (masks) the power/oc pins if set, like H1PM and
H2PM, not the opposite.
* MXC_OTG_PHYCTRL_OC_DIS_BIT disables the oc pin if set, like H1_OC_DIS, not the
opposite.
* Typos in comments.

Make ehci power and overcurrent polarities configurable. If not set, these new
configurartions keep the default register values so that existing board files
do not have to be changed.

Now that RTC support has been enabled for i.MX35, add RTC to the mx35_3ds board.

The i.MX35 has an RTC compatible with the i.MX31's, so enable its support even
if it's not very useful because it's not battery backed.

The data sheet of the i.MX35 says it is an ARM1136JF-S processor, version r1p3,
which, according to section "B.1. New instructions" of the ARM1136JF-S and
ARM1136J-S Technical Reference Manual, makes the i.MX35 CPU architecture not
only ARMv6, but ARMv6k.

This patch adds missing definitions for DISP, GPT and CCM pads.
These pins are not used by kernel, but may be helpful for custom boards.

The EHCI driver is not stable enough to be enabled by default. In v3.5,
it has at least the following problems:
- warning dump during bootup
- hang during suspend
- prevents CORE powerdomain from entering retention during idle (even
when no USB devices connected.)
This demonstrates that this driver has not been thoroughly tested and
therfore should not be enabled in the default defconfig.
In addition, the problems above cause new PM regressions which need be
addressed before this driver should be enabled in the default
defconfig.

commit c0357e975afdbbedab5c662d19bef865f02adc17
bnx2: stop using net_device.{base_addr, irq}.
removed netdev->base_addr so we need to update cnic to get the MMIO
base address from pci_resource_start(). Otherwise, mmap of the uio
device will fail.

Adding a device with limited QMI support. It does not support
normal QMI_WDS commands for connection management. Instead,
sending a QMI_CTL SET_INSTANCE_ID command is required to
enable the network interface:
01 0f 00 00 00 00 00 00 20 00 04 00 01 01 00 00
A number of QMI_DMS and QMI_NAS commands are also supported
for optional device management.
