When switching between low gain (high RSSI) and high gain settings, it
can take a few seconds to adjust to the current environment.
This can lead to short periods of time with extreme packet loss.
When switching from low_gain=1 to low_gain=2, start with the same gain
adjustment value instead of the lowest to avoid spikes of huge numbers
of false CCA events
Also avoid resetting adjustment values on switching between low_gain
values 0 and 1, since it affects only the upper limit of vga adjustment

The beacon timer drifts by 1 microsecond every TBTT. After 20 minutes
with a beacon interval of 100, the drift will be almost 12 ms, enough to
cause weird issues for devices in powersave mode.
Since the beacon timer is configured in units of 1/16 TU (64 us), we
need to adjust it once every 64 beacons and only for one beacon.

The USB completion callback does not disable interrupts while acquiring
the lock. We want to remove the local_irq_disable() invocation from
__usb_hcd_giveback_urb() and therefore it is required for the callback
handler to disable the interrupts while acquiring the lock.
The callback may be invoked either in IRQ or BH context depending on the
USB host controller.
Use the _irqsave() variant of the locking primitives.

I am removing the

with disabled interrupts which is the case now.

The ipw2x00 driver family uses get_seconds() to read the current time
for various purposes. This function is deprecated because of the 32-bit
time_t overflow, and it can cause unexpected behavior when the time
changes due to settimeofday() calls or leap second updates.
In many cases, we want to use monotonic time instead, however ipw2x00
explicitly tracks the time spent in suspend, so this changes the
driver over to use ktime_get_boottime_seconds(), which is slightly
slower, but not used in a fastpath here.

The get_seconds() function is deprecated because of the y2038 overflow.
In zd1211rw we don't even care about the absolute value, so this is
not a problem, but it's equally trivial to change to the non-deprecated
ktime_get_seconds().

The BIT macro uses unsigned long which some architectures handle as 32 bit
and therefore might cause macro's shift to overflow when used on a value
equals or larger than 32 (NL80211_STA_INFO_RX_DURATION and afterwards).
Since 'filled' member in station_info changed to u64, BIT_ULL macro
should be used with all NL80211_STA_INFO_* attribute types instead of BIT
to prevent future possible bugs when one will use BIT macro for higher
attributes by mistake.
This commit cleans up all usages of BIT macro with the above field
in wireless-drivers by changing it to BIT_ULL instead. In addition, there are
some places which don't use BIT nor BIT_ULL macros so align those as well.

This is a static checker fix, not something I have tested. The issue
is that on the second iteration through the loop, we jump forward by
le32_to_cpu(auth_req->length) bytes. The problem is that if the length
is more than "buflen" then we end up with a negative "buflen". A
negative buflen is type promoted to a high positive value and the loop
continues but it's accessing beyond the end of the buffer.
I believe the "auth_req->length" comes from the firmware and if the
firmware is malicious or buggy, you're already toasted so the impact of
this bug is probably not very severe.

There's a bug in *_encode_bits() in using ~field_multiplier() for
the check whether or not the constant value fits into the field,
this is wrong and clearly ~field_mask() was intended. This was
triggering for me for both constant and non-constant values.
Additionally, make this case actually into an compile error.
Declaring the extern function that will never exist with just a
warning is pointless as then later we'll just get a link error.
While at it, also fix the indentation in those lines I'm touching.
Finally, as suggested by Andy Shevchenko, add some tests and for
that introduce also u8 helpers. The tests don't compile without
the fix, showing that it's necessary.

We have wl12xx_boot() call wl12xx_enable_interrupts() and if we have

wlcore: ERROR ELP wakeup timeout!

only after that call pm_runtime_get_sync() when interrupts are enabled.
And only after that do the check for wl12xx_need_fw_change().

After enabling runtime PM, if we force hardware reset multiple times with:
# echo 1 > /sys/kernel/debug/ieee80211/phy0/wlcore/start_recovery
We will after few tries get the following error:
wlcore: ERROR timeout waiting for the hardware to complete initialization
And then wlcore is unable to reconnect until after the wlcore related modules
are reloaded.
Let's fix this by moving pm_runtime_put() earlier before we restart the hardware.
And let's use the sync version to make sure we're done before we restart.
Note that we still will get -EBUSY warning from wl12xx_sdio_set_power() but let's
fix that separately once we know exactly why we get the warning.

We can update wlcore to use PM runtime by adding functions for
wlcore_runtime_suspend() and wlcore_runtime_resume() and replacing
calls to wl1271_ps_elp_wakeup() and wl1271_ps_elp_sleep() with calls
to pm_runtime_get_sync() and pm_runtime_put().
Note that the new wlcore_runtime_suspend() and wlcore_runtime_resume()
functions are based on simplified versions of wl1271_ps_elp_sleep() and
wl1271_ps_elp_wakeup().
We don't want to use the old functions as we can now take advantage of
the runtime PM usage count. And we don't need the old elp_work at all.
And we can also remove WL1271_FLAG_ELP_REQUESTED that is no longer needed.
Pretty much the only place where we are not just converting the existing
functions is wl1271_op_suspend() where we add pm_runtime_put_noidle()
to keep the calls paired.
As the next step is to implement runtime PM autosuspend, let's not add
wrapper functions for the generic runtime PM calls. We would be getting
rid of any wrapper functions anyways.
After autoidle we should be able to start using Linux generic wakeirqs
for the padconf interrupt.

I've only seen this few times with the runtime PM patches enabled
so this one is probably not needed before that. This seems to
work currently based on the current PM implementation timer. Let's
apply this separately though in case others are hitting this issue.

Pull RISC-V updates from Palmer Dabbelt:
"This contains some small RISC-V updates I'd like to target for 4.18.
They are all fairly small this time. Here's a short summary, there's
more info in the commits/merges:
- a fix to __clear_user to respect the passed arguments.
- enough support for the perf subsystem to work with RISC-V's ISA
defined performance counters.
- support for sparse and cleanups suggested by it.
- support for R_RISCV_32 (a relocation, not the 32-bit ISA).
- some MAINTAINERS cleanups.
- the addition of CONFIG_HVC_RISCV_SBI to our defconfig, as it's
always present.
I've given these a simple build+boot test"

riscv/ftrace: Export _mcount when DYNAMIC_FTRACE isn't set
riscv: add riscv-specific predefines to CHECKFLAGS
riscv: split the declaration of __copy_user
