A crash is observed when a decrypted packet is processed in receive
path. get_rps_cpus() tries to dereference the skb->dev fields but it
appears that the device is freed from the poison pattern.

     |        name_hlist = (next = 0xAAAAAAAAAAAAAAAA, pprev =
0xAAAAAAAAAAA

Following are the sequence of events observed -

- Encrypted packet in receive path from netdevice is queued
- Encrypted packet queued for decryption (asynchronous)
- Netdevice brought down and freed
- Packet is decrypted and returned through callback in esp_input_done
- Packet is queued again for process in network stack using netif_rx

Since the device appears to have been freed, the dereference of
skb->dev in get_rps_cpus() leads to an unhandled page fault
exception.

Fix this by holding on to device reference when queueing packets
asynchronously and releasing the reference on call back return.

Pull tracing updates from Steven Rostedt:
 "Nothing major this round.  Mostly small clean ups and fixes.

  Some visible changes:

   - A new flag was added to distinguish traces done in NMI context.

   - Preempt tracer now shows functions where preemption is disabled but
     interrupts are still enabled.

  Other notes:

   - Updates were done to function tracing to allow better performance
     with perf.

   - Infrastructure code has been added to allow for a new histogram
     feature for recording live trace event histograms that can be
     configured by simple user commands.  The feature itself was just
     finished, but needs a round in linux-next before being pulled.

     This only includes some infrastructure changes that will be needed"

Pull thermal updates from Zhang Rui:

 - Fix a regression where bogus trip points on some Lenovo laptops start
   to screw up thermal control after commit 81ad4276 ("Thermal:
   initialize thermal zone device correctly").

   On these Lenovo laptops, a bogus passive trip point is reported,
   which is 0 degree Celsius.  Without commit 81ad4276, thermal zone
   fails to set cooling devices to proper cooling state, which is a bug.
   But with commit 81ad4276 applied, the processors are always
   throttled on these Lenovo laptops because the current temperature is
   always higher than the passive trip point.

   Fix things to ignore such bogus trip points.  (Zhang Rui)

 - Introduce Mediatek thermal driver.  (Sascha Hauer)

 - Introduce devm_ versions of OF thermal sensor register API.  (Laxman
   Dewangan)

 - Changes in Kconfigs to allow compile test on UM arch.  (Krzysztof

Let channels hold a reference on their network namespace.
Some channel types, like ppp_async and ppp_synctty, can have their
userspace controller running in a different namespace. Therefore they
can't rely on them to preclude their netns from being removed from
under them.

This patch corrects an oversight in which we were allowing the encap_level
value to pass from the outer headers to the inner headers.  As a result we
were incorrectly identifying UDP or GRE tunnels as also making use of ipip
or sit when the second header actually represented a tunnel encapsulated in
either a UDP or GRE tunnel which already had the features masked.

Commit a6745330 ("tools lib traceevent: Split pevent_print_event()
into specific functionality functions") broke apart the function
pevent_print_event() into three functions.

The first function prints the comm, pid and CPU, the second prints the
timestamp.

But that commit added the printing of the CPU in the timestamp function,
which now causes pevent_print_event() to duplicate the CPU output.

Remove the redundant printing of the record's CPU from the timestamp
function.

This removes the dependency on GPIOLIB for non faulty PHYs.

Indeed, without this patch, if GPIOLIB is not selected
devm_gpiod_get_optional() will return -ENOSYS and the driver probe
call will fail, regardless of the actual PHY hardware.

Out of the 3 PHYs supported by this driver (AT8030, AT8031, AT8035),
only AT8030 presents the issues that commit 13a56b44 ("net: phy:
at803x: Add support for hardware reset") attempts to work-around by
using a 'reset' GPIO line.

Hence, only AT8030 should depend on GPIOLIB operating properly.

The driver of course "knows" that the chip's reset signal is active low,
so  it drives the GPIO to 0  to reset the PHY and to 1 otherwise; however
all this will only work iff the GPIO  is  specified as active-high in the
device tree!  I think both the driver and the device trees (if there are
any -- I was unable to find them) need to be fixed in this case...

GPS rfkill support via pre-2009 WMI interface uses hp_wmi_get_sw_state()
and hp_wmi_get_hw_state() to query its current hard and soft block state,
respectively.

In hp_wmi_get_sw_state() a mask is calculated which bit should be checked
in an int value returned by firmware to get current block state: 0x200 <<
(r * 8) which with r being 3 for GPS results in overflow and mask of zero.
The same goes for hp_wmi_get_hw_state().

This effectively means that GPS rfkill on this WMI interface is considered
always both hard and soft blocked.

Unfortunately, later when rfkill subsystem calls hp_wmi_set_block() to sync
this block to hardware firmware at least on my old nc6400 gets confused and
sets both hard and soft blocks on WiFi and BT.

This happens for example on hp-wmi module load.

Since due to overflow described above it is dubious that this ever worked
correctly and HP laptops with modems having GPS support seem to all have
been released well past year 2009 let's just remove GPS rfkill support via
pre-2009 WMI interface.
