be88a1ada9 iwlwifi: nvm: remove mac address byte swapping in 8000 family
This fixes the byte order copying in the MAO (Mac Override
Section) section from the PNVM, as the byte swapping is not
required anymore in the 8000 family. Due to the byte
swapping, the driver was reporting an incorrect MAC
adddress.

00fd233ac4 iwlwifi: mvm: check time-event vif to avoid bad deletion
The time event is initialized relatively late in interface (mvmvif)
initialization, so it's possible to fail before that happens. As a
consequence, the driver will crash if it ever tries to delete this
time event in case initialization was unsuccessful.

Avoid this by using the time event's vif pointer to indicate validity.
The vif pointer is != NULL whenever the id is != TE_MAX, except for
this special error case where the vif pointer will have the correct
property (as the whole memory is cleared on allocation) whereas the
id is 0, causing a crash in trying to delete the time event from the
list.

02201e3f1b Minor merge needed, due to function move.
Main excitement here is Peter Zijlstra's lockless rbtree optimization to
 speed module address lookup.  He found some abusers of the module lock
 doing that too.
 
 A little bit of parameter work here too; including Dan Streetman's breaking
 up the big param mutex so writing a parameter can load another module (yeah,
 really).  Unfortunately that broke the usual suspects, !CONFIG_MODULES and
 !CONFIG_SYSFS, so those fixes were appended too.
 
 Cheers,
 Rusty.

923a8c1d80 iwlwifi: mvm: fix antenna selection when BT is active
When BT is active, we want to avoid the shared antenna for
management frame to make sure we don't disturb BT. There
was a bug in that code because it chose the antenna
BIT(ANT_A) where ANT_A is already a bitmap (0x1). This
means that the antenna chosen in the end was ANT_B.
While this is not optimal on devices with 2 antennas (it'd
disturb BT), it is critical on single antenna devices like
3160 which couldn't connect at all when BT was active.

This fixes:

b51d23e4e9 module: add per-module param_lock
Add a "param_lock" mutex to each module, and update params.c to use
the correct built-in or module mutex while locking kernel params.
Remove the kparam_block_sysfs_r/w() macros, replace them with direct
calls to kernel_param_[un]lock(module).

The kernel param code currently uses a single mutex to protect
modification of any and all kernel params.  While this generally works,
there is one specific problem with it; a module callback function
cannot safely load another module, i.e. with request_module() or even
with indirect calls such as crypto_has_alg().  If the module to be
loaded has any of its params configured (e.g. with a /etc/modprobe.d/*
config file), then the attempt will result in a deadlock between the
first module param callback waiting for modprobe, and modprobe trying to
lock the single kernel param mutex to set the new module's param.

This fixes that by using per-module mutexes, so that each individual module
is protected against concurrent changes in its own kernel params, but is
not blocked by changes to other module params.  All built-in modules
continue to use the built-in mutex, since they will always be loaded at
runtime and references (e.g. request_module(), crypto_has_alg()) to them
will never cause load-time param changing.

This also simplifies the interface used by modules to block sysfs access
to their params; while there are currently functions to block and unblock
sysfs param access which are split up by read and write and expect a single
kernel param to be passed, their actual operation is identical and applies
to all params, not just the one passed to them; they simply lock and unlock
the global param mutex.  They are replaced with direct calls to
kernel_param_[un]lock(THIS_MODULE), which locks THIS_MODULE's param_lock, or
if the module is built-in, it locks the built-in mutex.

8d0123748a mt7601u: don't warn about devices without per-rate power table
We expect EEPROM per-rate power table to be filled with
s6 values and warn user if values are invalid.  However,
there appear to be devices which don't have this section
of EEPROM initialized.  In such case we should ignore
the values and leave the driver power tables set to zero.

Note that vendor driver doesn't care about this case but
mt76x2 skips 0xff per value.  We take mt76x2's approach.

5b18ffb2d7 brcmfmac: use debugfs_create_devm_seqfile() helper function
Some time ago the function debugfs_create_devm_seqfile() was
introduced in debugfs. The caller simply needs to provide a
device pointer and read function. The function brcmf_debugfs_add_entry()
is now simply a wrapper only doing the work for CONFIG_BRCMDBG.

c161f29bd6 brcmfmac: remove watchdog reset from brcmf_pcie_buscoreprep()
The watchdog reset as done in brcmf_pcie_buscoreprep() is not
sufficient. It needs to modify PCIe core registers as well
which is properly done by brcmf_pcie_reset_device() after the
chip recognition is done. So the faulty watchdog reset can be
removed as it was causing driver reload to fail and hang the
system requiring a power-cycle. Instead the call to to the
brcmf_pcie_reset_device() function is done twice in the unload.

df738c2f0c brcmfmac: Update msgbuf read pointer quicker.
On device to host data using msgbuf the read pointer gets updated
once all data is processed. Updating this pointer more frequently
allows the firmware to add more data quicker. This will result in
slightly higher and more stable throughput on CPU bounded host
processors.

30686bf7f5 mac80211: convert HW flags to unsigned long bitmap
As we're running out of hardware capability flags pretty quickly,
convert them to use the regular test_bit() style unsigned long
bitmaps.

This introduces a number of helper functions/macros to set and to
test the bits, along with new debugfs code.

The occurrences of an explicit __clear_bit() are intentional, the
drivers were never supposed to change their supported bits on the
fly. We should investigate changing this to be a per-frame flag.
