ac_classify() expects a struct sk_buff* as its second argument, which is
a member of struct tx_complete_data. priv happens to be a pointer to
struct tx_complete_data, so passing it directly to ac_classify() leads
to wrong behaviour and occasional panics.
Since there is only one caller of wilc_wlan_txq_add_net_pkt and it
already knows the type behind this pointer, and the structure is already
in the header file, change the function signature to use the real type
instead of void* in order to prevent confusion.

Commit 68ad28a4cdd4 ("KVM: PPC: Book3S HV: Fix radix guest SLB side
channel") incorrectly removed the radix host instruction patch to skip
re-loading the host SLB entries when exiting from a hash
guest. Restore it.

Commit 68ad28a4cdd4 ("KVM: PPC: Book3S HV: Fix radix guest SLB side
channel") changed the older guest entry path, with the side effect
that vcpu->arch.slb_max no longer gets cleared for a radix guest.
This means that a HPT guest which loads some SLB entries, switches to
radix mode, runs the guest using the old guest entry path (e.g.,
because the indep_threads_mode module parameter has been set to
false), and then switches back to HPT mode would now see the old SLB
entries being present, whereas previously it would have seen no SLB
entries.
To avoid changing guest-visible behaviour, this adds a store
instruction to clear vcpu->arch.slb_max for a radix guest using the
old guest entry path.

sdw_update_slave_status will be invoked when a codec is attached,
and the codec driver will initialize the codec with regmap functions
while the codec device is pm_runtime suspended.
regmap routines currently rely on regular SoundWire IO functions,
which will call pm_runtime_get_sync()/put_autosuspend.
This causes a deadlock where the resume routine waits for an
initialization complete signal that while the initialization complete
can only be reached when the resume completes.
The only solution if we allow regmap functions to be used in resume
operations as well as during codec initialization is to use _no_pm
routines. The duty of making sure the bus is operational needs to be
handled above the regmap level.

acpi_walk_namespace can return success without executing our
callback which initializes info->handle.
If the random value in this structure is a valid address (which
is on the stack, so it's quite possible), then nothing bad will
happen, because:
sdw_intel_scan_controller
-> acpi_bus_get_device
-> acpi_get_device_data
-> acpi_get_data_full
-> acpi_ns_validate_handle
will reject this handle.
However, if the value from the stack doesn't point to a valid
address, we get this:

Currently, although set_bit() & test_bit() pairs are used as a fast-
path for initialized configurations. However, these atomic ops are
actually relaxed forms. Instead, load-acquire & store-release form is
needed to make sure uninitialized fields won't be observed in advance
here (yet no such corresponding bitops so use full barriers instead.)
