When the firmware asserts, we restart the device and reset
the relevant data we hold in the driver. BT Coex data was
not reset and because of that, the driver wouldn't
reconfigure the firmware properly after firmware restart.
Same for beacon filtering. Fix that.

When we associate, we may have heard the beacon before the
association. In that case, BSS_CHANGED_BEACON_INFO will be
set along with BSS_CHANGED_ASSOC in changes in
bss_info_change.
In this case, we didn't update the smart fifo nor beacon
filtering leaving those two feature disabled.

The mvm op_mode won't allocate the buffer for the transport
any more. The transport allocates its own buffer and mvm
is in charge of splicing the buffers in the debugfs hook.
This makes the repartition easier to handle.

The recent unified scan api change introduced issues
when stopping ongoing scans, since both regular and
sched scan now use same stopped notification.
When issuing a new scan right after a running one,
we get the "old" notification and handle it wrongly
as notification for the current scan.
Fix it by introducing a new function that make sure
we consume the pending notifications before issuing
a new scan.

According to new requirements, the ACK / CTS kill mask is
not related to reduced TX power anymore. This allows to
remove the code that tracked reduced TX power enablement
across different interfaces.
The ACK / CTS kill mask is now fetch from a table. It
depends on the Activity grading (activity from BT) and on
the Look Up Table (LUT) type.

The Remain On Channel framework added to the firmare is
a bit like time events. It allows the driver to request
the firmware to be on a certain channel for a certain time.
Unlike the time events, the ROC infrastructure doesn't need
a MAC context in the firmware - it uses a generic context
called "auxiliary framework".
This is useful for any offchannel activity that is not bound
to a specific MAC.
The flow is synchronized much like with time events:
1) The driver receives an action frame from the wpa_supplicant
via nl80211 that requests to be sent offchannel.
2) The driver sends an Aux ROC command (0x53) to the firmware.
3) The firmware responds with the unique id of the time event.
4) When time event starts, the driver puts the frame in the
Aux queue.
Special care needs to be taken when the time events ends:
the queue needs to be cleaned-up.

This commit is for correction of my misunderstanding about return value of
.put callback in ALSA Control interface.
According to 'Writing ALSA Driver' (*1), return value of the callback has
three patterns; 1: changed, 0: not changed, an negative value: fatal error.
But I misunderstood that it's boolean; zero or nonzero.

This commit uses different labels for control elements of digital input/output
interfaces to correct my misunderstanding about M-Audio Firewire 1814 and
ProjectMix I/O.
According to user manuals for these two models, they have two modes for
digital input; one is S/PDIF in both of optical and coaxial interfaces,
another is ADAT in optical interface only.
But in current implementation, a control element for it reduced labels which
a control element for digital output uses because of my misunderstanding
that optical interface is not available for digital input with S/PDIF mode.

Commit 554086d ("x86_32, entry: Do syscall exit work on badsys
(CVE-2014-4508)") introduced a regression in the x86_32 syscall entry
code, resulting in syscall() not returning proper errors for undefined
syscalls on CPUs supporting the sysenter feature.
The following code:
> int result = syscall(666);
> printf("result=%d errno=%d error=%s\n", result, errno, strerror(errno));
results in:
> result=666 errno=0 error=Success
Obviously, the syscall return value is the called syscall number, but it
should have been an ENOSYS error. When run under ptrace it behaves
correctly, which makes it hard to debug in the wild:
> result=-1 errno=38 error=Function not implemented
The %eax register is the return value register. For debugging via ptrace
the syscall entry code stores the complete register context on the
stack. The badsys handlers only store the ENOSYS error code in the
ptrace register set and do not set %eax like a regular syscall handler
would. The old resume_userspace call chain contains code that clobbers
%eax and it restores %eax from the ptrace registers afterwards. The same
goes for the ptrace-enabled call chain. When ptrace is not used, the
syscall return value is the passed-in syscall number from the untouched
%eax register.
Use %eax as the return value register in syscall_badsys and
sysenter_badsys, like a real syscall handler does, and have the caller
push the value onto the stack for ptrace access.

x86_64 boots and displays fine, but booting x86_32 with CONFIG_HIGHMEM
has frozen with a blank screen throughout 3.16-rc on this ThinkPad T420s,
with i915 generation 6 graphics.
Fix 9d0a6fa6c5e6 ("drm/i915: add render state initialization"): kunmap()
takes struct page * argument, not virtual address. Which the compiler
kindly points out, if you use the appropriate u32 *batch, instead of
silencing it with a void *.
Why did bisection lead decisively to nearby 229b0489aa75 ("drm/i915:
add null render states for gen6, gen7 and gen8")? Because the u32
deposited at that virtual address by the previous stub failed the
PageHighMem test, and so did no harm.

Commit 75b57ecf9 refactored device tree nodes to use kobjects such that they
can be exposed via /sysfs. A secondary commit 0829f6d1f furthered this rework
by moving the kobect initialization logic out of of_node_add into its own
of_node_init function. The inital commit removed the existing kref_init calls
in the pseries dlpar code with the assumption kobject initialization would
occur in of_node_add. The second commit had the side effect of triggering a
BUG_ON during DLPAR, migration and suspend/resume operations as a result of
dynamically added nodes being uninitialized.
This patch fixes this by adding of_node_init calls in place of the previously
removed kref_init calls.

bit for the arithmetic right-shift instructions was not correct on 64-bit

An af_iucv stress test showed -EPIPE results for sendmsg()
calls. They are caused by quiescing a path even though it has
been already severed by peer. For IUCV transport shutdown()
consists of 2 steps:
(1) sending the shutdown message to peer
(2) quiescing the iucv path
If the iucv path between these 2 steps is severed due to peer
closing the path, the quiesce step is no longer needed.

====================
pull request [net]: batman-adv 20140721
here you have two fixes that we have been testing for quite some time
(this is why they arrived a bit late in the rc cycle).
Patch 1) ensures that BLA packets get dropped and not forwarded to the
mesh even if they reach batman-adv within QinQ frames. Forwarding them
into the mesh means messing up with the TT database of other nodes which
can generate all kind of unexpected behaviours during route computation.
Patch 2) avoids a couple of race conditions triggered upon fast VLAN
deletion-addition. Such race conditions are pretty dangerous because
they not only create inconsistencies in the TT database of the nodes
in the network, but such scenario is also unrecoverable (unless
nodes are rebooted).

There is a benign buffer overflow in ip_options_compile spotted by
AddressSanitizer[1] :
Its benign because we always can access one extra byte in skb->head
(because header is followed by struct skb_shared_info), and in this case
this byte is not even used.

The link adjustment callback can be called as frequently as desired
by the PHY library, as such, let's avoid doing a Read/Modify/Write
sequence if nothing changed, since these register accesses can be
expensive.
