Input packet processing for local sockets involves two major demuxes.
One for the route and one for the socket.
But we can optimize this down to one demux for certain kinds of local
sockets.
Currently we only do this for established TCP sockets, but it could
at least in theory be expanded to other kinds of connections.
If a TCP socket is established then it's identity is fully specified.
This means that whatever input route was used during the three-way
handshake must work equally well for the rest of the connection since
the keys will not change.
Once we move to established state, we cache the receive packet's input
route to use later.
Like the existing cached route in sk->sk_dst_cache used for output
packets, we have to check for route invalidations using dst->obsolete
and dst->ops->check().
Early demux occurs outside of a socket locked section, so when a route
invalidation occurs we defer the fixup of sk->sk_rx_dst until we are
actually inside of established state packet processing and thus have
the socket locked.

Constant Charge Current(CC) is charging parameter which limit the
maximum current which can be pumped into the battery during charge cycle.
Constant Charge Voltage(CV) is also charging parameter which limit the
maximum voltage that battery can reach during charge cycle.
It is very common practice that at low or high temperatures we
do not charge the batteries upto it's fullest charge voltage
to avoid battery and user safety issues.
These sysfs properties will be useful for debug and to implement
certain user space policies like "Charging limited due to OverTemp".

Currently regulator_register_fixed() uses a constant name to register a
fixed dummy regulator. This is sufficient in principle, since there is no
reason to register multiple such regulators. The user can simply supply all
consumers in one array and use it to initialise such a regulator. However,
in some cases it can be convenient to register multiple such regulators.
This is also a prerequisite for the upcoming patch, that will add a voltage
parameter to this function. The original function is provided as a wrapper
macro.

here is our second pull request for net-next. In this series Federico
Vaga adds a pci driver for c_can/d_can hardware using the existing
generic c_can driver. The remaining 6 patches are by Oliver Hartkopp.
He adds CANFD support to the CAN stack while keeping binary
compatibility for existing applications. CANFD is an extension to the
existing CAN standard, it allows longer CAN frames and/or higher data
rates. There's no real hardware available yet, but this series adds
CANFD support to the vcan driver.

Here goes the first Bluetooth pull request for 3.6, we have
queued quite a lot of work. Andrei Emeltchenko added the AMP
Manager code, a lot of work is needed, but the first bit are
already there. This code is disabled by default. Mat Martineau
changed the whole L2CAP ERTM state machine code, replacing
the old one with a new implementation. Besides that we had
lot of coding style fixes (to follow net rules), more l2cap
core separation from socket and many clean ups and fixed all
over the tree.
Along with the above, there is a healthy dose of ath9k, iwlwifi,
and other driver updates. There is also another pull from the
wireless tree to resolve some merge issues. I also fixed-up some
merge discrepencies between net-next and wireless-next.

The S5M8767A can't know status of ap reset.
So, After AP watchdog reset, AP can't boot normally.
Problem can be happened like below condition.
- AP Bootable lowest voltage(vdd_arm): 0.9v
- AP DVFS voltage table: 0.8v, 0.9v, 1.0v
- During AP works on lowest voltage(0.8V), watchdog reset is asserted
- AP can't boot, because vdd arm is still 0.8v
Solution
- Basic concept:
After ap watchdog reset, GPIO configuration is changed by default value
- S5M8767A has function of voltage control with gpio (8 levels with 3 gpios)
- Set bootable voltage on level 0 -> can work with default gpio configuration
- In the probing, Change voltage control level from level 0 to level 1
- Execute normal dvfs operation on level 1
- After watchdog reset, ap gpio is set by default value
- PMIC operation mode is changed by ap reset (level1 -> level0)
- Regardless of previous vdd_arm voltage, AP always can be booted.

In "9cb0176 netfilter: add glue code to integrate nfnetlink_queue and ctnetlink"

I have moved the conntrack part into nfnetlink_queue_ct.c to avoid
peppering the entire nfnetlink_queue.c code with ifdefs.
I also needed to rename nfnetlink_queue.c to nfnetlink_queue_pkt.c
to update the net/netfilter/Makefile to support conditional compilation
of the conntrack integration.
This patch also adds CONFIG_NETFILTER_QUEUE_CT in case you want to explicitly

Commit 5963e317b1 ("ftrace/x86: Do not change stacks in DEBUG when
calling lockdep") prevented lockdep calls from the int3 breakpoint handler
from reseting the stack if a function that was called was in the process
of being converted for tracing and had a breakpoint on it. The idea is,
before calling the lockdep code, do a load_idt() to the special IDT that
kept the breakpoint stack from reseting. This worked well as a quick fix
for this kernel release, until a certain config caused a lockup in the
function tracer start up tests.
Investigating it, I found that the load_idt that was used to prevent
the int3 from changing stacks was itself being traced!
Even though the config had CONFIG_OPTIMIZE_INLINING disabled, and
all 'inline' tags were set to always inline, there were still cases that
it did not inline! This was caused by CONFIG_PARAVIRT_GUEST, where it
would add a pointer to the native_load_idt() which made that function
to be traced.
Commit 45959ee7aa ("ftrace: Do not function trace inlined functions")
only touched the 'inline' tags when CONFIG_OPMITIZE_INLINING was enabled.
PARAVIRT_GUEST shows that this was not enough and we need to also
mark always_inline with notrace as well.

Currently there is a 'chicken and egg' issue when the DS is also the mounted
MDS. The nfs_match_client() reference from nfs4_set_ds_client bumps the
cl_count, the nfs_client is not freed at umount, and nfs4_deviceid_purge_client
is not called to dereference the MDS usage of a deviceid which holds a
reference to the DS nfs_client. The result is the umount program returns,
but the nfs_client is not freed, and the cl_session hearbeat continues.
The MDS (and all other nfs mounts) lose their last nfs_client reference in
nfs_free_server when the last nfs_server (fsid) is umounted.
The file layout DS lose their last nfs_client reference in destroy_ds
when the last deviceid referencing the data server is put and destroy_ds is
called. This is triggered by a call to nfs4_deviceid_purge_client which
removes references to a pNFS deviceid used by an MDS mount.
The fix is to track how many pnfs enabled filesystems are mounted from
this server, and then to purge the device id cache once that count reaches
zero.

HID standard allows sending a feature request to the device which is
answered by an HID report. uhid implements this by sending a UHID_FEATURE
event to user-space which then must answer with UHID_FEATURE_ANSWER. If it
doesn't do this in a timely manner, the request is discarded silently.
We serialize the feature requests, that is, there is always only a single
active feature-request sent to user-space, other requests have to wait.
HIDP and USB-HID do it the same way.
Because we discard feature-requests silently, we must make sure to match
a response to the corresponding request. We use sequence-IDs for this so
user-space must copy the ID from the request into the answer.
Feature-answers are ignored if they do not contain the same ID as the
currently pending feature request.
Internally, we must make sure that feature-requests are synchronized with
UHID_DESTROY and close() events. We must not dead-lock when closing the
HID device, either, so we have to use separate locks.

Some drivers that use non-standard HID features require raw output reports
sent to the device. We now forward these requests directly to user-space
so the transport-level driver can correctly send it to the device or
handle it correspondingly.
There is no way to signal back whether the transmission was successful,
moreover, there might be lots of messages coming out from the driver
flushing the output-queue. However, there is currently no driver that
causes this so we are safe. If some drivers need to transmit lots of data
this way, we need a method to synchronize this and can implement another
UHID_OUTPUT_SYNC event.
