Currently we cache the number of input and output paths going to/from a
widget only within a power update sequence. But not in between power update
sequences.
But we know how changes to the DAPM graph affect the number of input (form a
source) and output (to a sink) paths of a widget and only need to
recalculate them if a operation has been performed that might have changed
them.
* Adding/removing or connecting/disconnecting a path means that the for
the source of the path the number of output paths can change and for
the sink the number of input paths can change.
* Connecting/disconnecting a widget has the same effect has connecting/
disconnecting all paths of the widget. So for the widget itself the
number of inputs and outputs can change, for all sinks of the widget
the number of inputs can change and for all sources of the widget the
number of outputs can change.
* Activating/Deactivating a stream can either change the number of
outputs on the sources of the widget associated with the stream or the
number of inputs on the sinks.
Instead of always invalidating all cached numbers of input and output paths
for each power up or down sequence this patch restructures the code to only
invalidate the cached numbers when a operation that might change them has
been performed. This can greatly reduce the number of DAPM power checks for
some very common operations.
Since per DAPM operation typically only either change the number of inputs
or outputs the number of path checks is reduced by at least 50%. The number
of neighbor checks is also reduced about the same percentage, but since the
number of neighbors encountered when walking from sink to source is not the
same as when walking from source to sink the actual numbers will slightly
vary from card to card (e.g. for a mixer we see 1 neighbor when walking from
source to sink, but the number of inputs neighbors when walking from source
to sink).
Bigger improvements can be observed for widgets with multiple connected
inputs and output (e.g. mixers probably being the most widespread form of
this). Previously we had to re-calculate the number of inputs and outputs
on all input and output paths. With this change we only have to re-calculate
the number of outputs on the input path that got changed and the number of
inputs on the output paths.
E.g. imagine the following example:
A --> B ----.
v
M --> N --> Z <-- S <-- R
|
v
X
Widget Z has multiple input paths, if any change was made that cause Z to be
marked as dirty the power state of Z has to be re-computed. This requires to
know the number of inputs and outputs of Z, which requires to know the
number of inputs and outputs of all widgets on all paths from or to Z.
Previously this meant re-computing all inputs and outputs of all the path
going into or out of Z. With this patch in place only paths that actually
have changed need to be re-computed.
If the system is idle (or the part of the system affected by the changed
path) the number of path checks drops to either 0 or 1, regardless of how
large or complex the DAPM context is. 0 if there is no connected sink and no
connected source. 1 if there is either a connected source or sink, but not
both. The number of neighbor checks again will scale accordingly and will be
a constant number that is the number of inputs or outputs of the widget for
which we did the path check.
When loading a state file or switching between different profiles typically
multiple mixer and mux settings are changed, so we see the benefit of this
patch multiplied for these kinds of operations.
Testing with the ADAU1761 shows the following changes in DAPM stats for
changing a single Mixer switch for a Mixer with 5 inputs while the DAPM
context is idle.

The state of endpoint widgets is affected by that card's power state.
Endpoint widgets that do no have the ignore_suspend flag set will be
considered inactive during suspend. So they have to be re-checked and marked
dirty after the card's power state changes. Currently the input and output
widgets are marked dirty instead, this works most of the time since
typically a path from one endpoint to another will go via a input or output
widget. But marking the endpoints dirty is technically more correct and will
also work for odd corner cases.

Supply widgets do not count towards the input and output widgets of their
neighbors and for supply widgets themselves we do not care for the number
of input or output paths. This means that a path that connects to a supply
widget effectively behaves the same as a path that as the weak property set.
This patch adds a new path flag that gets set to true when the path is
connected to at least one supply widget. If a path with the flag set is
encountered in is_connected_{input,output}_ep() is is skipped in the same
way that weak paths are skipped. This slightly brings down the number of
path checks.
Since both the weak and the supply flag are implemented as bitfields which
are stored in the same word there is no runtime overhead due to checking
both rather than just one and also the size of the path struct is not
increased by this patch. Another advantage is that we do not have to handle
supply widgets in is_connected_{input,output}_ep() anymore since it will
never be called for supply widgets. The only exception is from
dapm_widget_power_read_file() where a check is added to special case supply
widgets.
Testing with the ADAU1761, which has a handful of supply widgets, shows the
following changes in the DAPM stats for a playback stream start.

DAPM widgets can be classified into four categories:
* supply: Supply widgets do not affect the power state of their
non-supply widget neighbors and unlike other widgets a
supply widget is not powered up when it is on an active
path, but when at least on of its neighbors is powered up.
* source: A source is a widget that receives data from outside the
DAPM graph or generates data. This can for example be a
microphone, the playback DMA or a signal generator. A source
widget will be considered powered up if there is an active
path to a sink widget.
* sink: A sink is a widget that transmits data to somewhere outside
of the DAPM graph. This can e.g. be a speaker or the capture
DMA. A sink widget will be considered powered up if there is
an active path from a source widget.
* normal: Normal widgets are widgets not covered by the categories
above. A normal widget will be considered powered up if it
is on an active path between a source widget and a sink
widget.
The way the number of input and output paths for a widget is calculated
depends on its category. There are a bunch of factors which decide which
category a widget is. Currently there is no formal classification of these
categories and we calculate the category of the widget based on these
factors whenever we want to know it. This is at least once for every widget
during each power update sequence. The factors which determine the category
of the widgets are mostly static though and if at all change rather seldom.
This patch introduces three new per widget flags, one for each of non-normal
widgets categories. Instead of re-computing the category each time we want
to know them the flags will be checked. For the majority of widgets the
category is solely determined by the widget id, which means it never changes
and only has to be set once when the widget is created. The only widgets
with dynamic categories are:
snd_soc_dapm_dai_out: Is considered a sink iff the capture stream is
active, otherwise normal.
snd_soc_dapm_dai_in: Is considered a source iff the playback stream
is active, otherwise normal.
snd_soc_dapm_input: Is considered a sink iff it has no outgoing
paths, otherwise normal.
snd_soc_dapm_output: Is considered a source iff it has no incoming
paths, otherwise normal.
snd_soc_dapm_line: Is considered a sink iff it has no outgoing paths
and is considered a source iff it has no incoming paths,
otherwise normal.
For snd_soc_dapm_dai_out/snd_soc_dapm_dai_in widgets the category will be
updated when a stream is started or stopped. For the other dynamic widgets
the category will be updated when a path connecting to it is added or
removed.
Introducing those new widget categories allows to make
is_connected_{output,input}_ep, which are among the hottest paths of the
DAPM algorithm, more generic and significantly shorter.
The before and after sizes for is_connected_{output,input}_ep are:
On ARM (defconfig + CONFIG_SND_SOC):
function old new delta
is_connected_output_ep 480 340 -140
is_connected_input_ep 456 352 -104
On amd64 (defconfig + CONFIG_SND_SOC):
function old new delta
is_connected_output_ep 579 427 -152
is_connected_input_ep 563 427 -136
Which is about a 25%-30% decrease, other architectures are expected to have
similar numbers. At the same time the size of the snd_soc_dapm_widget struct
does not change since the new flags are stored in the same word as the
existing flags.
Note: that since the per widget 'ext' flag was only used to decide whether a
snd_soc_dapm_input or snd_soc_dapm_output widget was a source or a sink it
is now unused and can be removed.

This feature is defined in IEEE Std 802.11-2012, 10.23.13. It allows
the AP devices to keep track of the hardware-address-to-IP-address
mapping of the mobile devices within the WLAN network.
The AP will learn this mapping via observing DHCP, ARP, and NS/NA
frames. When a request for such information is made (i.e. ARP request,
Neighbor Solicitation), the AP will respond on behalf of the
associated mobile device. In the process of doing so, the AP will drop
the multicast request frame that was intended to go out to the wireless
medium.
It was recommended at the LKS workshop to do this implementation in
the bridge layer. vxlan.c is already doing something very similar.
The DHCP snooping code will be added to the userspace application
(hostapd) per the recommendation.
This RFC commit is only for IPv4. A similar approach in the bridge
layer will be taken for IPv6 as well.

Current cpuset API for checking if a zone/node is allowed to allocate
from looks rather awkward. We have hardwall and softwall versions of
cpuset_node_allowed with the softwall version doing literally the same
as the hardwall version if __GFP_HARDWALL is passed to it in gfp flags.
If it isn't, the softwall version may check the given node against the
enclosing hardwall cpuset, which it needs to take the callback lock to
do.
Such a distinction was introduced by commit 02a0e53d82 ("cpuset:
rework cpuset_zone_allowed api"). Before, we had the only version with
the __GFP_HARDWALL flag determining its behavior. The purpose of the
commit was to avoid sleep-in-atomic bugs when someone would mistakenly
call the function without the __GFP_HARDWALL flag for an atomic
allocation. The suffixes introduced were intended to make the callers
think before using the function.
However, since the callback lock was converted from mutex to spinlock by
the previous patch, the softwall check function cannot sleep, and these
precautions are no longer necessary.
So let's simplify the API back to the single check.

header will be have similar function like cfg80211 header. The cfg80211
header contains the wiphy struct which is identically the wpan_phy
struct inside 802.15.4 subsystem.

When #iio-cells is greater than '0', the driver could provide
a custom of_xlate function that reads the *args* and returns
the appropriate index in registered IIO channels array.
Add simple translation function, suitable for the most 1:1
mapped channels in IIO chips, and use it when driver did not
provide custom implementation.

Systematically removing the LE connection parameters and autoconnect
action is inconvenient for rebonding without disconnecting from
userland (i.e. unpairing followed by repairing without
disconnecting). The parameters will be lost after unparing and
userland needs to take care of book-keeping them and re-adding them.
This patch allows userland to forget about parameter management when
rebonding without disconnecting. It defers clearing the connection
parameters when unparing without disconnecting, giving a chance of
keeping the parameters if a repairing happens before the connection is
closed.

There are scenarios when autoconnecting to a device after the
reception of an ADV_IND report (action 0x02), in which userland
might want to examine the report's contents.
For instance, the Service Data might have changed and it would be
useful to know ahead of time before starting any GATT procedures.
Also, the ADV_IND may contain Manufacturer Specific data which would
be lost if not propagated to userland. In fact, this patch results
from the need to rebond with a device lacking persistent storage which
notifies about losing its LTK in ADV_IND reports.
This patch appends the ADV_IND report which triggered the
autoconnection to the EIR Data in the Device Connected event.

The PXA168 Ethernet IP support MII and RMII connection to its PHY.
Currently, pxa168 platform_data does not provide a way to pass that
and there is one user of pxa168 platform_data (mach-mmp/gplug).
Given the pinctrl settings of gplug it uses RMII, so add and pass
a corresponding phy_interface_t.

as what I usually had for the _whole_ rc period.
There are a few bad bugs where the guest can OOPS or crash the host. We
have also started looking at attack models for nested virtualization;
bugs that usually result in the guest ring 0 crashing itself become
more worrisome if you have nested virtualization, because the nested
guest might bring down the non-nested guest as well. For current
uses of nested virtualization these do not really have a security
impact, but you never know and bugs are bugs nevertheless.
A lot of these bugs are in 3.17 too, resulting in a large number of
stable@ Ccs. I checked that all the patches apply there with no
conflicts.
