some Intel Alder Lake xHC hosts on ChromeOS platforms need special
workarounds touching port registers at xHC pci host hibernate.
Export xhci_port_state_to_neutral() and xhci_find_slot_id_by_port()
so they can be called from xhci-pci.c and thus the xhci-pci module.

ADL-N systems have the same issue as ADL-P, where a large boot firmware
delay is seen if USB ports are left in U3 at shutdown. So apply the
XHCI_RESET_TO_DEFAULT quirk to ADL-N as well.
This patch depends on commit 34cd2db408d5 ("xhci: Add quirk to reset
host back to default state at shutdown").
The issue it fixes is a ~20s boot time delay when booting from S5. It
affects ADL-N devices, and ADL-N support was added starting from v5.16.

When HCE(Host Controller Error) is set, it means that the xhci hardware
controller has an error at this time, but the current xhci driver
software does not log this event.
By adding an HCE event detection in the xhci interrupt processing
interface, a warning log is output to the system, which is convenient
for system device status tracking.

Note that there is no need reconfigure the line speed in hardware when

This driver implements CPU frequency scaling for Apple Silicon SoCs,
including M1 (t8103), M1 Max/Pro/Ultra (t600x), and M2 (t8112).
Each CPU cluster has its own register set, and frequency management is
fully automated by the hardware; the driver only has to write one
register. There is boost frequency support, but the hardware will only
allow their use if only a subset of cores in a cluster are in
non-deep-idle. Since we don't support deep idle yet, these frequencies
are not achievable, but the driver supports them. They will remain
disabled in the device tree until deep idle is implemented, to avoid
confusing users.
This driver does not yet implement the memory controller performance
state tuning that usually accompanies higher CPU p-states. This will be
done in a future patch.

This patch remove this limitation by changing trap action offload to not use
MLX5_ATTR_FLAG_SLOW_PATH flag and instead set the flow destination table
explicitly to be the slow table. This will allow offload of the additional

Per the device spec, MTTs/KLMs list in a UMR WQE must be aligned to 64B.
Per our SW design, the MTT/KLMs list would need alignment only if it's
too small, for example on PPC when PAGE_SIZE is 64KB, and only 4 pages
are needed to cover a MPWQE of size 256KB.
Padding, if needed, is taken into account when calculating the UMR WQE
fields (ds_cnt and xlt_octowords), however no entries are provided,
instead garbage is passed.
No real harm though, as these parts act as gaps between the RX MPWQEs
and not used by any of them. Hence, in practice, device does not try to
write any incoming packet to them. Still, prefer providing clean padding
marking the end of the list, and do not map garbage into the RQ memory
region.

Earlier commits in this series allow battery-powered systems to build
their kernels with the default-disabled CONFIG_RCU_LAZY=y Kconfig option.
This Kconfig option causes call_rcu() to delay its callbacks in order
to batch them. This means that a given RCU grace period covers more
callbacks, thus reducing the number of grace periods, in turn reducing
the amount of energy consumed, which increases battery lifetime which
can be a very good thing. This is not a subtle effect: In some important
use cases, the battery lifetime is increased by more than 10%.
This CONFIG_RCU_LAZY=y option is available only for CPUs that offload
callbacks, for example, CPUs mentioned in the rcu_nocbs kernel boot
parameter passed to kernels built with CONFIG_RCU_NOCB_CPU=y.
Delaying callbacks is normally not a problem because most callbacks do
nothing but free memory. If the system is short on memory, a shrinker
will kick all currently queued lazy callbacks out of their laziness,
thus freeing their memory in short order. Similarly, the rcu_barrier()
function, which blocks until all currently queued callbacks are invoked,
will also kick lazy callbacks, thus enabling rcu_barrier() to complete
in a timely manner.
However, there are some cases where laziness is not a good option.
For example, synchronize_rcu() invokes call_rcu(), and blocks until
the newly queued callback is invoked. It would not be a good for
synchronize_rcu() to block for ten seconds, even on an idle system.
Therefore, synchronize_rcu() invokes call_rcu_hurry() instead of
call_rcu(). The arrival of a non-lazy call_rcu_hurry() callback on a
given CPU kicks any lazy callbacks that might be already queued on that
CPU. After all, if there is going to be a grace period, all callbacks
might as well get full benefit from it.
Yes, this could be done the other way around by creating a
call_rcu_lazy(), but earlier experience with this approach and
feedback at the 2022 Linux Plumbers Conference shifted the approach
to call_rcu() being lazy with call_rcu_hurry() for the few places
where laziness is inappropriate.
And another call_rcu() instance that cannot be lazy is the one in the
scsi_eh_scmd_add() function. Leaving this instance lazy results in
unacceptably slow boot times.
Therefore, make scsi_eh_scmd_add() use call_rcu_hurry() in order to
revert to the old behavior.

divisor calculation
This Cadence QSPI IP has a 4-bit clock divisor field
for baud rate division. For example:
0b0000 = /2
0b0001 = /4
0b0010 = /6
...
0b1111 = /32
The maximum divisor is 32
(when div = CQSPI_REG_CONFIG_BAUD_MASK).
If we assume a reference clock of 500MHz and we set
our spi-max-frequency to something low, such as 10 MHz.
The calculated bit field for the divisor ends up being:
DIV_ROUND_UP(500000000/(2*10000000))-1 = 25
25 is 0b11001... which truncates to a divisor field of 0b1001 (or /20).
This is higher than our anticipated max-frequency of 10MHz
(500MHz/20 = 25 MHz). Instead, let's make sure we're always using
the maximum divisor (/32) in this case and give the user a warning about
the rate adjustment.

intel_dsi->ports contains bitmask of enabled ports and correspondingly
logic for selecting port for VBT packet sending must use port specific
bitmask when deciding appropriate port.

When (size != 0 || ptrs->lvds_ entries != 3), the program tries to
free() the ptrs. However, the ptrs is not created by calling kzmalloc(),
but is obtained by pointer offset operation.
This may lead to memory leaks or undefined behavior.
Fix this by replacing the arguments of kfree() with ptrs_block.

Users of intel_gt_retire_requests_timeout() expect 0 return value on
success. However, we have no protection from passing back 0 potentially
returned by a call to dma_fence_wait_timeout() when it succedes right
after its timeout has expired.
Replace 0 with -ETIME before potentially using the timeout value as return
code, so -ETIME is returned if there are still some requests not retired
after timeout, 0 otherwise.
v3: Use conditional expression, more compact but also better reflecting
intention standing behind the change.
v2: Move the added lines down so flush_submission() is not affected.

Commit b97060a99b01 ("drm/i915/guc: Update intel_gt_wait_for_idle to work
with GuC") extended the API of intel_gt_retire_requests_timeout() with an
extra argument 'remaining_timeout', intended for passing back unconsumed
portion of requested timeout when 0 (success) is returned. However, when
request retirement happens to succeed despite an error returned by a call
to dma_fence_wait_timeout(), that error code (a negative value) is passed
back instead of remaining time. If we then pass that negative value
forward as requested timeout to intel_uc_wait_for_idle(), an explicit BUG
will be triggered.
If request retirement succeeds but an error code is passed back via
remaininig_timeout, we may have no clue on how much of the initial timeout
might have been left for spending it on waiting for GuC to become idle.
OTOH, since all pending requests have been successfully retired, that
error code has been already ignored by intel_gt_retire_requests_timeout(),
then we shouldn't fail.
Assume no more time has been left on error and pass 0 timeout value to
intel_uc_wait_for_idle() to give it a chance to return success if GuC is
already idle.
v3: Don't fail on any error passed back via remaining_timeout.
v2: Fix the issue on the caller side, not the provider.

The fence is always initialized in huc_init_early, but the cleanup in
huc_fini is only being run if HuC is enabled. This causes a leaking of
the debug object when HuC is disabled/not supported, which can in turn
trigger a warning if we try to register a new debug offset at the same
address on driver reload.
To fix the issue, make sure to always run the cleanup code.

This reverts commit c0071be0e16c461680d87b763ba1ee5e46548fde.
The cited commit removed the validity checks which initialized the
window_sz and never removed the use of the now uninitialized variable,
so now we are left with wrong value in the window size and the following
clang warning: [-Wuninitialized]
drivers/net/ethernet/mellanox/mlx5/core/en_accel/macsec.c:232:45:
warning: variable 'window_sz' is uninitialized when used here
MLX5_SET(macsec_aso, aso_ctx, window_size, window_sz);
Revet at this time to address the clang issue due to lack of time to
test the proper solution.
