Since blk_mq_ops.reinit_request is only called from inside
blk_mq_reinit_tagset(), make this function pointer an argument of
blk_mq_reinit_tagset() instead of a member of struct blk_mq_ops.
This patch does not change any functionality but makes
blk_mq_reinit_tagset() calls easier to read and to analyze.

The buffer passed to btrfs_ioctl_tree_search* functions have to be at least
sizeof(struct btrfs_ioctl_search_header). If this is not the case then the
ioctl should return -EOVERFLOW and set the uarg->buf_size to the minimum
required size. Currently btrfs_ioctl_tree_search_v2 would return an -EOVERFLOW
error with ->buf_size being set to the value passed by user space. Fix this by
removing the size check and relying on search_ioctl, which already includes it

Use the observation that the EC command/data register addresses are
sufficient to determine if two EC devices are equivelent to modify
acpi_is_boot_ec().
Then, for the removed comparison factors, EC ID and EC GPE, they need
to be synchronized for the boot_ec:
1. Before registering the BIOS-provided EC event handlers in
acpi_ec_register_query_methods(), the namespace node holding
_Qxx methods should be located. The real namespace PNP0C09
device location then is apparently more trustworthy than the
ECDT EC ID.
2. Because of the ASUS quirks, the ECDT EC GPE is more trustworthy
than the namespace PNP0C09 device's _GPE setting.
Use the above observations to synchronize the boot_ec settings in
acpi_ec_add().
Finally, change the order of acpi_ec_ecdt_start() and acpi_ec_add(),
called from acpi_bus_register_driver(), so as to follow the fast path
of determining the location of _Qxx.

Because of that, when we got an ampdu_action with

ping pong with the firmware:
1) Set the station as 'draining'
2) Get a failed Tx status (DRAINED)
3) Send a BAR because of the failed Tx status
(loop of 2 and 3)
This loop wasn't endless since the BAR isn't sent on a
queue that would trigger a "nested" BAR.

If a time event is already scheduled when trying to schedule one for
channel switch, the code assumes the channel switch is already
scheduled and no further action is required.
However, it is possible that the scheduled time event is actually
for session protection (e.g. when the first beacon after association
contains the CSA IE). In this case the channel switch will not be
scheduled which will finally lead to disconnection.
Fix this by removing the old time event and schduling a new one for
the channel switch.

The commit 213e08ad60
("drm/i915/bxt: add bxt dsi gpio element support")
enables GPIO support for Broxton based platforms.
While using that API we might get into troubles in the future, because
we can't rely on label name in the driver since vendor firmware might
provide any GPIO pin there, e.g. "reset", and even mark it in _DSD (in
which case the request will fail).
To avoid inconsistency and potential issues we have two options:
a) generate GPIO ACPI mapping table and supply it via
acpi_dev_add_driver_gpios(), or
b) just pass NULL as connection ID.
The b) approach is much simpler and would work since the driver relies
on GPIO indices only. Moreover, the _CRS fallback mechanism, when
requesting GPIO, has been made stricter, and supplying non-NULL
connection ID when neither _DSD, nor GPIO ACPI mapping is present, is
making request fail.
