b44915927c x86/iommu: Fix header comments regarding standard and _FINISH macros
The comment line regarding IOMMU_INIT and IOMMU_INIT_FINISH
macros is incorrect:

  "The standard vs the _FINISH differs in that the _FINISH variant
  will continue detecting other IOMMUs in the call list..."

It should be "..the *standard* variant will continue
detecting..."

Fix that. Also, make it readable while at it.

549c5dc19e gpio: dwapb: remove dependencies
The Synopsys DesignWare DWAPB GPIO block is popular to
synthesize amongst many architectures: X86, ARM, ARC.
The driver was restricted to only these archs due to
using [read|write]l_relaxed() accessors that were not
universally available in the past,
but as of commit 9439eb3ab9
"asm-generic: io: implement relaxed accessor macros as
conditional wrappers" these accessors are available on all
archs so this should not be a problem any more. Enable the
driver for all archs.

24fef9022a ALSA: hda/generic - Don't override power_filter when power_save_node is set
Currently the generic parser sets codec->power_filter when
power_save_node flag is set.  But this overrides the existing filter
that has been already set by the codec driver, thus it looses some
features.  Instead, set the default power_filter only when it's not
set yet.

Add the check of power_save_node flag at the beginning of the function
so that it skips the rest if the flag isn't set.  In this way, we can
call this function safely no matter whether the widget power-saving is

d5ac0100a9 ALSA: hda/generic - Fix wrong initial power state for fixed pins
When the widget power-saving is enabled, the first automute hook
invocation checks through the whole pins and it also tries to
synchronize the power state.  However, this results in a wrong state
because it calls unconditionally snd_hda_jack_detect_state().
This patch adds a check of jack detectability before the actual jack
detection call.

8d86e4fccc mmc: sdhci-esdhc-imx: Call mmc_of_parse()
Currently it is not possible to use 'mmc-pwrseq-simple' property with this
driver because mmc_of_parse() is never called.

mmc_of_parse() calls mmc_pwrseq_alloc() that manages MMC power sequence and
allows passing GPIOs in the devicetree to properly power/reset the Wifi
chipset.

When using mmc_of_parse() we no longer need to have custom code to request
card-detect and write-protect pins, as this can now be handled by the mmc
core.

Tested on a imx6sl-warp board where BT/Wifi is functional and also on a
imx6q-sabresd.

8886a6fd19 mmc: dw_mmc: Increase cmd11 timeout to 500ms
Although the cmd11 interrupt should come within 2ms, that's a very
short time.  Let's increase the timeout to be really sure that we
don't get an accidnetal timeout.  One case in particular this is
useful is if you've got a serial console and printk in just the right
places.  Under that scenario I've seen delays of up to 130ms before
the interrupt fired.

CMD11 is only sent during card insertion, so this extra timeout
shouldn't be terrible.

76184ac17e mmc: dw_mmc: fix fifo ordering in big endian
The dw_mmc driver changes to make the IO accesors endian agnostic did not
take into account the fifo accesses do not need to be swapped. To fix this
add a mmci_fifo_read/write wrapper to allow these to be passed through the
IO without being swapped.

Since these are now specific functions, it would be easier just to store
the pointer to the fifo registers in the host block instead of the offset
to them. So change the host->data_offset to host->fifo_reg (which also
means we catch all the places this is read or written).

6687c42fa7 mmc: dw_mmc: change idmac descriptor files to __le32
The dw_mmc driver does not take into account the processor may be in
big endian when writing the descriptors. Change the descriptors for
the 32bit IDMA to use __le32 and ensure they are suitably swapped
before writing.

Note, this has not been tested as the socfpga driver does not try to
use idma.

9efe2731db ALSA: hda - Always allow access for POWER_STATE verbs via regmap
The hdac regmap code checks whether the codec is powered on while
accessing, but there must be an exception -- the verbs to control the
power state.

Currently HD-audio driver doesn't access them via regmap, so this
patch doesn't fix any current behavior, but it's just for future.

01ac33c1f9 locking/mutex: Further simplify mutex_spin_on_owner()
Similar to what Linus suggested for rwsem_spin_on_owner(), in
mutex_spin_on_owner() instead of having while (true) and
breaking out of the spin loop on lock->owner != owner, we can
have the loop directly check for while (lock->owner == owner) to
improve the readability of the code.

It also shrinks the code a bit:

   text    data     bss     dec     hex filename
   3721       0       0    3721     e89 mutex.o.before

0fe29fd1cd Bluetooth: Read LE remote features during connection establishment
When establishing a Bluetooth LE connection, read the remote used
features mask to determine which features are supported. This was
not really needed with Bluetooth 4.0, but since Bluetooth 4.1 and
also 4.2 have introduced new optional features, this becomes more
important.

This works the same as with BR/EDR where the connection enters the
BT_CONFIG stage and hci_connect_cfm call is delayed until the remote
features have been retrieved. Only after successfully receiving the
remote features, the connection enters the BT_CONNECTED state.

6aa248145a switch kernel_sendmsg() and kernel_recvmsg() to iov_iter_kvec()
For kernel_sendmsg() that eliminates the need to play with setfs();
for kernel_recvmsg() it does *not* - a couple of callers are using
it with non-NULL ->msg_control, which would be treated as userland
address on recvmsg side of things.

In all cases we are really setting a kvec-backed iov_iter, though.

e76ea26142 hwmon: (gpio-fan) Move the thermal registration after registration is complete
Thermal framework may already be ready and cooling policies might
already be functional when we are attempting to register gpio fan as
a cooling device. This can be reproduced by changing probe order in
which registration of various modules are done in a system. In such
a case, kernel generates an oops since the data structures are not
completely populated with the wrong assumption that thermal framework
is not yet ready. Fix this by reordering the thermal framework
registration to occur after hwmon registration of the fan is complete.

Example kernel oops:

FastOpen requests are not like other regular request sockets.

They do not yet use rsk_timer : tcp_fastopen_queue_check()
simply manually removes one expired request from fastopenq->rskq_rst
list.

Therefore, tcp_check_req() must not call mod_timer_pending(),
otherwise we crash because rsk_timer was not initialized.
