New network transport protocols want NIC drivers to get hardware timestamps
of all incoming packets, and possibly all outgoing packets.
One example is the upcoming 'Swift congestion control' which is used by TCP
transport and is the primary need for timecounter_cyc2time(). This means
timecounter_cyc2time() can be called more than 100 million times per second
on a busy server.
Inlining timecounter_cyc2time() brings a 12% improvement on a UDP receive
stress test on a 100Gbit NIC.
Note that FDO, LTO, PGO are unable to magically help for this case,
presumably because NIC drivers are almost exclusively shipped as modules.
Add an unlikely() around the cc_cyc2ns_backwards() case, even if FDO (when
used) is able to take care of this optimization.

As describe in the help string, the user might want to disable these
tests if they don't like to see stacktraces/BUG etc in their kernel log.
However, if they enable PANIC_ON_OOPS, these tests also crash the
machine, which it's safe to assume _almost_ nobody wants.
One might argue that _absolutely_ nobody ever wants their kernel to
crash so this should just be a hard dependency instead of a default.
However, since this is rather special code that's anyway concerned with
deliberately doing "bad" things, the normal rules don't seem to apply,
hence prefer flexibility and allow users to set up a crashing Kconfig if
they so choose.

The commit d5d399efff ("printk/nbcon: Release nbcon consoles ownership
in atomic flush after each emitted record") prevented stall of a CPU
which lost nbcon console ownership because another CPU entered
an emergency flush.
But there is still the problem that the CPU doing the emergency flush
might cause a stall on its own.
Let's go even further and restore IRQ in the atomic flush after
each emitted record.
It is not a complete solution. The interrupts and/or scheduling might
still be blocked when the emergency atomic flush was called with
IRQs and/or scheduling disabled. But it should remove the following
lockup:
mlx5_core 0000:03:00.0: Shutdown was called

In this case, nbcon_atomic_flush_pending() is called from
printk_kthreads_shutdown() with IRQs and scheduling enabled.
Note that __nbcon_atomic_flush_pending_con() is directly called also from
nbcon_device_release() where the disabled IRQs might break PREEMPT_RT
guarantees. But the atomic flush is called only in emergency or panic
situations where the latencies are irrelevant anyway.
An ultimate solution would be a touching of watchdogs. But it would hide
all problems. Let's do it later when anyone reports a stall which does
not have a better solution.

Requesting a delegation on a file from the userland fcntl() interface
currently succeeds when there are conflicting opens present.
This is because the lease handling code ignores conflicting opens for
FL_LAYOUT and FL_DELEG leases. This was a hack put in place long ago,
because nfsd already checks for conflicts in its own way. The kernel
needs to perform this check for userland delegations the same way it is
done for leases, however.
Make this dependent on the lease_manager by adding a new
->lm_open_conflict() lease_manager operation and have
generic_add_lease() call that instead of check_conflicting_open().
Morph check_conflicting_open() into a ->lm_open_conflict() op that is
only called for userland leases/delegations. Set the
->lm_open_conflict() operations for nfsd to trivial functions that
always return 0.

Zhang Yi points out that the dynamic folio_batch allocation in
iomap_fill_dirty_folios() is problematic for the ext4 on iomap work
that is under development because it doesn't sufficiently handle the
allocation failure case (by allowing a retry, for example). We've
also seen lockdep (via syzbot) complain recently about the scope of
the allocation.
The dynamic allocation was initially added for simplicity and to
help indicate whether the batch was used or not by the calling fs.
To address these issues, put the batch on the stack of
iomap_zero_range() and use a flag to control whether the batch
should be used in the iomap folio lookup path. This keeps things
simple and eliminates allocation issues with lockdep and for ext4 on
iomap.
While here, also clean up the fill helper signature to be more
consistent with the underlying filemap helper. Pass through the
return value of the filemap helper (folio count) and update the
lookup offset via an out param.

When there is no fallback possibility available for the function topology
use it is better to try to create a profile for the card in best effort
manner, leaving out non supported links for example.
As an example: some laptops present SSPx-BT link but we don't have fragment
yet to support this. If we only have support for functional topology
without monolithic fallback then we would fail the card creation.
The reason why the monolithic topology works on the same device is that it
does not have the SSPx-BT link handled, it is ignored.
In case when there is no fallback possibility we should try to create the
card with links that we support as best effort instead of failing and
leaving the user without a card.

If on-demand DSP boot is used we need to make sure that the DSP is booted
up - which might not be the case - since we need ChainDMA in normal, non
DSPless mode for the BRA to work.

With the introduction of on-demand DSP boot the rpm status not necessary
tells that the DSP firmware is booted up.
Introduce the sof_client_boot_dsp() which can be used to make sure that
the DSP is booted and it can handle IPCs.
Update the client drivers to use the new function where it is expected that
the DSP is booted up.
