There are some new flags in the channel flags that we don't know

Newer versions of A000 devices come with two diffenent RF modules.
The PCI_ID, the subsystem ID and the RF ID are identical in these two cases,
so we need to differentiate them by using the CSR_HW_RF_ID register-
in order to load the appropriate firmware.

The code did not consider the case that the channel switch counter
is <= 1, which would result with an inaccurate calculation of the
time event apply time.
As the specification states that in case of counter == 0 the switch
occurs at any time after the reception the frame, and for counter == 1
the switch would happens before the next TBTT, schedule the time
event immediately.

When we flush a queue, the packets will have a 'failed'
status but we shouldn't send a BAR. This check was missing.
Because of that, when we got an ampdu_action with
IEEE80211_AMPDU_TX_STOP_FLUSH, we started the following
ping pong with the firmware:
1) Set the station as 'draining'
2) Get a failed Tx status (DRAINED)
3) Send a BAR because of the failed Tx status
(loop of 2 and 3)
This loop wasn't endless since the BAR isn't sent on a
queue that would trigger a "nested" BAR.

If a time event is already scheduled when trying to schedule one for
channel switch, the code assumes the channel switch is already
scheduled and no further action is required.
However, it is possible that the scheduled time event is actually
for session protection (e.g. when the first beacon after association
contains the CSA IE). In this case the channel switch will not be
scheduled which will finally lead to disconnection.
Fix this by removing the old time event and schduling a new one for
the channel switch.

The hardlockup detector on x86 uses a performance counter based on unhalted
CPU cycles and a periodic hrtimer. The hrtimer period is about 2/5 of the
performance counter period, so the hrtimer should fire 2-3 times before the
performance counter NMI fires. The NMI code checks whether the hrtimer
fired since the last invocation. If not, it assumess a hard lockup.
The calculation of those periods is based on the nominal CPU
frequency. Turbo modes increase the CPU clock frequency and therefore
shorten the period of the perf/NMI watchdog. With extreme Turbo-modes (3x
nominal frequency) the perf/NMI period is shorter than the hrtimer period
which leads to false positives.
A simple fix would be to shorten the hrtimer period, but that comes with
the side effect of more frequent hrtimer and softlockup thread wakeups,
which is not desired.
Implement a low pass filter, which checks the perf/NMI period against
kernel time. If the perf/NMI fires before 4/5 of the watchdog period has
elapsed then the event is ignored and postponed to the next perf/NMI.
That solves the problem and avoids the overhead of shorter hrtimer periods
and more frequent softlockup thread wakeups.

Way back when we established inode block-map redo log items, it was
discovered that we needed to prevent the VFS from evicting inodes during
log recovery because any given inode might be have bmap redo items to
replay even if the inode has no link count and is ultimately deleted,
and any eviction of an unlinked inode causes the inode to be truncated
and freed too early.
To make this possible, we set MS_ACTIVE so that inodes would not be torn
down immediately upon release. Unfortunately, this also results in the
quota inodes not being released at all if a later part of the mount
process should fail, because we never reclaim the inodes. So, set
MS_ACTIVE right before we do the last part of log recovery and clear it
immediately after we finish the log recovery so that everything
will be torn down properly if we abort the mount.

Given both program types are effecitvely doing the same in the
prologue, just reuse the one that we had for tc and only adapt
to the corresponding drop verdict value. That way, we don't need
to have the duplicate from 8a31db5615 ("bpf: add access to sock
fields and pkt data from sk_skb programs") to maintain.

In smap_do_verdict(), the fall-through branch leads to call
preempt_enable() twice for the SK_REDIRECT, which creates an
imbalance. Only enable it for all remaining cases again.

vio_device_id are not supposed to change at runtime. All functions
working with vio_device_id provided by <asm/vio.h> work with
const vio_device_id. So mark the non-const structs as const.

We are guaranteed to have a NULL ri->map in this branch since
we test for it earlier, so we don't need to reset it here.

Using parent->regs[] when propagating REG_LIVE_READ for spilled regs
doesn't work since parent->regs[] denote the set of normal registers
but not spilled ones. Propagate to the correct regs.
