bio->bi_ioc is never set so always NULL. Remove references to it in
bio_disassociate_task() and in rq_ioc() and delete this field from
struct bio. With this change, rq_ioc() always returns
current->io_context without the need for a bio argument. Further
simplify the code and make it more readable by also removing this
helper, which also allows to simplify blk_mq_sched_assign_ioc() by
removing its bio argument.

We currently only really support sync poll, ie poll with 1 IO in flight.
This prepares us for supporting async poll.
Note that the returned value isn't necessarily 100% accurate. If poll
races with IRQ completion, we assume that the fact that the task is now
runnable means we found at least one entry. In reality it could be more
than 1, or not even 1. This is fine, the caller will just need to take
this into account.

Now that there are no more users of path_component_name for Sparc
outside of the PDT code and all users of device_node.full_name are
converted to use "%pOF" printf specifier, we can align Sparc with FDT
and store just the base node name and unit address in full_name. This
makes path_component_name redundant, so it can be removed.
As full_name is used by printf specifiers, set it as early as possible.

40GbE Intel Wired LAN Driver Updates 2018-11-14
This series contains updates to i40e and virtchnl.
Lance Roy updates i40e to use lockdep_assert_held() instead of
spin_is_locked(), since it is better suited to check locking
requirements.
Jan improves the code readability in XDP by adding the use of a local
variable. Provides protection on methods that create/modify/destroy
VF's via locking mechanism to prevent unstable behaviour and potential
kernel panics.
Krzysztof adds a hardware capability flag to indicate whether firmware
supports stopping the LLDP agent.
Patryk replaces the use of strncpy() with strlcpy() to ensure the buffer
is NULL terminated.
Mitch fixes the issue of trying to start nway on devices that do not
support auto-negotiation, by checking the autoneg state before
attempting to restart nway.
Alice updates virtchnl to keep the checks all together for ease of
readability and consistency. Also fixed a "off by one" error in the
number of traffic classes being calculated.
Richard fixed VF port VLANs, where the priority bits were incorrectly
set because the incorrect shift and mask bits were being used.
Alan adds a bit to set and check if a timeout recovery is already
pending to prevent overlapping transmit timeout recovery.

Instead of passing a global GPIO number for the enable GPIO, pass
a descriptor looked up from the device tree node or the board file
decriptor table for the regulator.
There is a single board file passing the GPIOs for LDO1 and LDO2
through platform data, so augment this to pass descriptors
associated with the i2c device as well.
The special GPIO enable DT property for the enable GPIO is
nonstandard but this was accomodated in
commit 6a537d48461deacc57c07ed86d9915e5aa4b3539
"gpio: of: Support regulator nonstandard GPIO properties".

The new memory EFI reservation feature we introduced to allow memory
reservations to persist across kexec may trigger an unbounded number
of calls to memblock_reserve(). The memblock subsystem can deal with
this fine, but not before memblock resizing is enabled, which we can
only do after paging_init(), when the memory we reallocate the array
into is actually mapped.
So break out the memreserve table processing into a separate routine
and call it after paging_init() on arm64. On ARM, because of limited
reviewing bandwidth of the maintainer, we cannot currently fix this,
so instead, disable the EFI persistent memreserve entirely on ARM so
we can fix it later.

cros_ec_get_next_event() is documented to return 0 for success and
negative for errors. It currently returns negative for some errors, and
non-negative (number of bytes received) for success (including some "no
data available" responses as zero). This mostly works out OK, because the
callers were more or less ignoring the documentation, and only treating
positive values as success (and indepdently checking the modification of
'wakeup').
Let's button this up by avoiding pretending to handle event/wakeup
distinctions when no event info was retrieved (i.e., returned 0 bytes).
And fix the documentation of cros_ec_get_host_event() and
cros_ec_get_next_event() to accurately describe their behavior.

First we have a patch by Oliver Hartkopp which changes the raw socket's
raw_sendmsg() to return an error value if the user tries to send a CANFD
frame to a CAN-2.0 device.
The next two patches are by Jimmy Assarsson and fix potential problems
in the kvaser_usb driver.

remove a duplicate include.
Eugeniu Rosca patch adds more binding documentation to the rcar_can
driver bindings. The next two patches are by Fabrizio Castro for the
rcar_can driver and fixes a problem in the driver's probe function and
document the r8a774a1 binding.
Lukas Wunner's patch fixes a recpetion problem in hi311x driver by
switching from edge to level triggered interruts.
The next three patches all target the flexcan driver. Pankaj Bansal's
patch unconditionally unlocks the last mailbox used for RX. Alexander
Stein provides a better workaround for a hardware limitation when
sending RTR frames, by using the last mailbox for TX, resulting in fewer
lost frames. The patch by me simplyfies the driver, by making a runtime
value a compile time constant.
The following 4 patches are by me and provide the groundwork for the
next patches by Oleksij Rempel. To avoid code duplication common code in
the common CAN driver infrastructure is factured out and error handling
is cleaned up.
The next 4 patches are by Oleksij Rempel and fix the problem in the
flexcan driver that other processes see TX frames arrive out of order
with ragards to a RX'ed frame (which are send by a different system on
the CAN bus as the result of our TX frame).

Distros are concerned about totally disabling the kexec_load syscall.
As a compromise, the kexec_load syscall will only be disabled when
CONFIG_KEXEC_VERIFY_SIG is configured and the system is booted with
secureboot enabled.
This patch defines the new arch specific function called
arch_ima_get_secureboot() to retrieve the secureboot state of the system.
