With the cdclk state, all the .modeset_commit_cdclk() hooks are
now pointless wrappers. Let's replace them with just a .set_cdclk()
function pointer. However let's wrap that in a small helper that
does the state comparison and prints a unified debug message across
all platforms. We didn't even have the debug print on all platforms
previously. This reduces the clutter in intel_atomic_commit_tail() a
little bit.

The current dev_cdclk vs. cdclk vs. atomic_cdclk_freq is quite a mess.
So here I'm introducing the "actual" and "logical" naming for our
cdclk state. "actual" is what we'll bash into the hardware and "logical"
is what everyone should use for state computaion/checking and whatnot.
We'll track both using the intel_cdclk_state as both will need other
differing parameters than just the actual cdclk frequency.
While doing that we can at the same time unify the appearance of the
.modeset_calc_cdclk() implementations a little bit.
v2: Commit dev_priv->cdclk.actual since that already has the
new state by the time .modeset_commit_cdclk() is called.

Introduce intel_cdclk state which for now will track the cdclk
frequency, the vco frequency and the reference frequency (not sure we
want the last one, but I put it there anyway). We'll also make the
.get_cdclk() function fill out this state structure rather than
just returning the current cdclk frequency.
One immediate benefit is that calling .get_cdclk() will no longer
clobber state stored under dev_priv unless ex[plicitly told to do
so. Previously it clobbered the vco and reference clocks stored
there on some platforms.
We'll expand the use of this structure to actually precomputing the
state and whatnot later.

The session protection set for association is only removed when

However, mac80211 may set both on association (in case a beacon was
already received). In this case, mac80211 will not set
BSS_CHANGED_BEACON_INFO on the next beacons because it has already
notified the beacon change, so the session protection is never removed
(until the session protection ends).
When a CSA is received within this time, the station will fail to
folllow the channel switch because it cannot schedule the time event.

Currently, when getting a RFKILL interrupt, the transport enters a flow
in which it stops the device, disables other interrupts, etc. After
stopping the device, the transport resets the hw, and sleeps. During
the sleep, a context switch occurs and host commands are sent by upper
layers (e.g. mvm) to the fw. This is possible since the op_mode layer
and the transport layer hold different mutexes.
Since the STATUS_RFKILL bit isn't set, the transport layer doesn't
recognize that RFKILL was toggled on, and no commands can actually be
sent, so it enqueues the command to the tx queue and sets a timer on
the queue.
After switching context back to stopping the device, STATUS_RFKILL is
set, and then the transport can't send the command to the fw.
This eventually results in a queue hang.
Fix this by setting STATUS_RFKILL immediately when
the interrupt is fired.

This patch fixes a bug where incoming task management requests
can be explicitly aborted during an active LUN_RESET, but who's
struct work_struct are canceled in-flight before execution.
This occurs when core_tmr_drain_tmr_list() invokes cancel_work_sync()
for the incoming se_tmr_req->task_cmd->work, resulting in cmd->work
for target_tmr_work() never getting invoked and the aborted TMR
waiting indefinately within transport_wait_for_tasks().
To address this case, perform a CMD_T_ABORTED check early in
transport_generic_handle_tmr(), and invoke the normal path via
transport_cmd_check_stop_to_fabric() to complete any TMR kthreads
blocked waiting for CMD_T_STOP in transport_wait_for_tasks().
Also, move the TRANSPORT_ISTATE_PROCESSING assignment earlier
into transport_generic_handle_tmr() so the existing check in
core_tmr_drain_tmr_list() avoids attempting abort the incoming
se_tmr_req->task_cmd->work if it has already been queued into
se_device->tmr_wq.

However, this scenario can happen when a dynamically generated

explicit NodeACL contains a different LUN mapping than the
default provided by the WWN endpoint.
So instead of triggering BUG_ON(), go ahead and fail instead
following the original pre RCU conversion logic.
