0d07c0ec43 x86/kprobes: Fix optprobe to detect INT3 padding correctly
Commit

  7705dc8557 ("x86/vmlinux: Use INT3 instead of NOP for linker fill bytes")

changed the padding bytes between functions from NOP to INT3. However,
when optprobe decodes a target function it finds INT3 and gives up the
jump optimization.

Instead of giving up any INT3 detection, check whether the rest of the
bytes to the end of the function are INT3. If all of them are INT3,
those come from the linker. In that case, continue the optprobe jump
optimization.

 [ bp: Massage commit message. ]

Commit 01bb86b380 ("driver core: Add fwnode_init()") was supposed to
fix up all instances of fwnode creation to use fwnode_init(). But looks
like this instance was missed. This causes a NULL pointer dereference
during device_add() [1]. So, fix it.

2f5fbc4305 irqchip/qcom-pdc: Fix phantom irq when changing between rising/falling
We have a problem if we use gpio-keys and configure wakeups such that
we only want one edge to wake us up.  AKA:
  wakeup-event-action = <EV_ACT_DEASSERTED>;
  wakeup-source;

Specifically we end up with a phantom interrupt that blocks suspend if
the line was already high and we want wakeups on rising edges (AKA we
want the GPIO to go low and then high again before we wake up).  The
opposite is also problematic.

Specifically, here's what's happening today:
1. Normally, gpio-keys configures to look for both edges.  Due to the
   current workaround introduced in commit c3c0c2e18d ("pinctrl:
   qcom: Handle broken/missing PDC dual edge IRQs on sc7180"), if the
   line was high we'd configure for falling edges.
2. At suspend time, we change to look for rising edges.
3. After qcom_pdc_gic_set_type() runs, we get a phantom interrupt.

We can solve this by just clearing the phantom interrupt.

NOTE: it is possible that this could cause problems for a client with
very specific needs, but there's not much we can do with this
hardware.  As an example, let's say the interrupt signal is currently
high and the client is looking for falling edges.  The client now
changes to look for rising edges.  The client could possibly expect
that if the line has a short pulse low (and back high) that it would
always be detected.  Specifically no matter when the pulse happened,
it should either have tripped the (old) falling edge trigger or the
(new) rising edge trigger.  We will simply not trip it.  We could
narrow down the race a bit by polling our parent before changing
types, but no matter what we do there will still be a period of time
where we can't tell the difference between a real transition (or more
than one transition) and the phantom.

Add the timeout if the entry was removed explicitly. This can happen

module removal, netdev notifier (nat/masquerade device went down),
ctnetlink and so on.

Add the protocol state too for the destroy message to check for abnormal

d1b0c33850 ath11k: implement suspend for QCA6390 PCI devices
Now that all the needed pieces are in place implement suspend support QCA6390
PCI devices. All other devices will return -EOPNOTSUPP during suspend. The
suspend is implemented by switching the firmware to WoW mode during suspend, so
the firmware will be running on low power mode while host is in suspend.

At the moment we are not able to shutdown and fully power off the device due to
bugs in MHI subsystem, so WoW mode is a workaround for the time being.

During suspend we enable WoW mode, disable CE irq and DP irq, then put MHI to
suspend state.  During resume, driver resumes MHI firstly, then enables CE irq
and dp IRQ, and sends WoW wakeup command to firmware.

dropped.  So host gets time out and WoW suspend failed.

5dadbe4e37 ath10k: add atomic protection for device recovery
When it has more than one restart_work queued meanwhile, the 2nd
restart_work is very easy to break the 1st restart work and lead
recovery fail.

Add a flag to allow only one restart work running untill
device successfully recovered.

It already has flag ATH10K_FLAG_CRASH_FLUSH, but it can not use this
flag again, because it is clear in ath10k_core_start. The function
ieee80211_reconfig(called by ieee80211_restart_work) of mac80211 do
many things and drv_start(call to ath10k_core_start) is 1st thing,
when drv_start complete, it does not mean restart complete. So it
add new flag and clear it in ath10k_reconfig_complete, because it
is the last thing called from drv_reconfig_complete of function
ieee80211_reconfig, after it, the restart process finished.

The new counters halt_poll_success_ns and halt_poll_fail_ns do not count
events. Instead they provide a time, and mess up our statistics. Therefore,
we should exclude them.
Removal is currently implemented with an exempt list. If more counters like
these appear, we can think about a more general rule like excluding all
fields name "*_ns", in case that's a standing convention.

34c0f6f269 KVM: mmu: Fix SPTE encoding of MMIO generation upper half
Commit cae7ed3c2c ("KVM: x86: Refactor the MMIO SPTE generation handling")
cleaned up the computation of MMIO generation SPTE masks, however it
introduced a bug how the upper part was encoded:
SPTE bits 52-61 were supposed to contain bits 10-19 of the current
generation number, however a missing shift encoded bits 1-10 there instead
(mostly duplicating the lower part of the encoded generation number that
then consisted of bits 1-9).

In the meantime, the upper part was shrunk by one bit and moved by
subsequent commits to become an upper half of the encoded generation number
(bits 9-17 of bits 0-17 encoded in a SPTE).

In addition to the above, commit 56871d444b ("KVM: x86: fix overlap between SPTE_MMIO_MASK and generation")
has changed the SPTE bit range assigned to encode the generation number and
the total number of bits encoded but did not update them in the comment
attached to their defines, nor in the KVM MMU doc.
Let's do it here, too, since it is too trivial thing to warrant a separate
commit.
