Pull s390 fixes from Alexander Gordeev:
- The function __storage_key_init_range() expects the end address to be
the first byte outside the range to be initialized. Fix the callers
that provide the last byte within the range instead.
- 3270 Channel Command Word (CCW) may contain zero data address in case
there is no data in the request. Add data availability check to avoid
erroneous non-zero value as result of virt_to_dma32(NULL) application
in cases there is no data
- Add missing CFI directives for an unwinder to restore the return
address in the vDSO assembler code
- NUL-terminate kernel buffer when duplicating user space memory region
on Channel IO (CIO) debugfs write inject
- Fix wrong format string in zcrypt debug output
- Return -EBUSY code when a CCA card is temporarily unavailabile
- Restore a loop that retries derivation of a protected key from a
secure key in cases the low level reports temporarily unavailability
with -EBUSY code

On stm32mp1xx based machines (and others) a PWM consumer has to disable
the PWM because an enabled PWM refuses to suspend. So check the
LED_SUSPENDED flag and depending on that set the .enabled property.

When we check for state values returned by the FW, we only cover part of
the 0:7 range. Make sure we catch FW inconsistencies by adding a default
to the switch statement, and flagging the group state as unknown in that
case.
When an unknown state is detected, we trigger a reset, and consider the
group as unusable after that point, to prevent the potential corruption
from creeping in other places if we continue executing stuff on this
context.

Currently, led pattern trigger uses timer_list to schedule brightness
changing. As we know from timer_list API [1], it's not accurate to
milliseconds and depends on HZ granularity.
Example:
"0 10 0 0 50 10 50 0 100 10 100 0 150 10 150 0 200 10 200 0 250 10 250 0",
we expect it to be 60ms long, but it can actually be up to ~120ms
(add ~10ms for each pattern when HZ == 100).
But sometimes, userspace needs time accurate led patterns to make sure
that pattern will be executed during expected time slot.
To achieve this goal the patch introduces optional hrtimer usage for
led trigger pattern, because hrtimer is microseconds accurate timer.

Contrary to i915, in xe ADL-N is kept as a different platform, not a
subplatform of ADL-P. Since the display side doesn't need to
differentiate between P and N, i.e. IS_ALDERLAKE_P_N() is never called,
just fixup the compat header to check for both P and N.
Moving ADL-N to be a subplatform would be more complex as the firmware
loading in xe only handles platforms, not subplatforms, as going forward
the direction is to check on IP version rather than
platforms/subplatforms.
Fix warning when initializing display:
xe 0000:00:02.0: [drm:intel_pch_type [xe]] Found Alder Lake PCH
------------[ cut here ]------------
xe 0000:00:02.0: drm_WARN_ON(!((dev_priv)->info.platform == XE_ALDERLAKE_S) && !((dev_priv)->info.platform == XE_ALDERLAKE_P))
And wrong paths being taken on the display side.

Pull firewire fixes from Takashi Sakamoto:
"Two driver fixes:
- The firewire-ohci driver for 1394 OHCI hardware does not fill time
stamp for response packet when handling asynchronous transaction to
local destination. This brings an inconvenience that the response
packet is not equivalent between the transaction to local and
remote. It is fixed by fulfilling the time stamp with hardware
time. The fix should be applied to Linux kernel v6.5 or later as
well.
- The nosy driver for Texas Instruments TSB12LV21A (PCILynx) has
long-standing issue about the behaviour when user space application
passes less size of buffer than expected. It is fixed by returning
zero according to the convention of UNIX-like systems"

When you create a submenu using the 'menu' syntax, there is no
ambiguity about its end because the code between 'menu' and 'endmenu'
becomes the submenu.
In contrast, 'menuconfig' does not have the corresponding end marker.
Instead, the end of the submenu is inferred from symbol dependencies.
This is detailed in Documentation/kbuild/kconfig-language.rst, starting
line 348. It outlines two methods to place the code under the submenu:
(1) Open an if-block immediately after 'menuconfig', enclosing the
submenu content within it
(2) Add 'depends on' to every symbol intended for the submenu
Many subsystems opt for (1) because it reliably maintains the submenu
structure.
The DRM subsystem adopts (2). The submenu ends when the sequence of
'depends on DRM' breaks. It can be confirmed by running a GUI frontend
such as 'make menuconfig' and visiting the DRM menu:
< > Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) ----
If you toggle this, you will notice most of the DRM-related options
appear below it, not in the submenu.
I highly recommend the approach (1). Obviously, (2) is not reliable,
as the submenu breaks whenever someone forgets to add 'depends on DRM'.
This commit encloses the entire DRM configuration with 'if DRM' and
'endif', except for DRM_PANEL_ORIENTATION_QUIRKS.
Note:
Now, 'depends on DRM' properties inside the if-block are all redundant.
I leave it as follow-up cleanups.

code should always be selected by the driver that needs it, for the
convenience of the final user configuring a kernel.
The user who configures a kernel should not need to know which helpers
are needed for the driver he is interested in. Making a driver depend
on helper code means that the user needs to know which helpers to enable
first, which is very user-unfriendly.

driver notifies the RoCE driver via ULP_STOP before the reset
and via ULP_START after the reset, all under RTNL_LOCK. The
RoCE driver can take a long time if there are a lot of QPs to
destroy, so it is not ideal to hold the global RTNL lock.
Rely on the new en_dev_lock mutex instead for ULP_STOP and
ULP_START. For the most part, we move the ULP_STOP call before
we take the RTNL lock and move the ULP_START after RTNL unlock.
Note that SRIOV re-enablement must be done after ULP_START
or RoCE on the VFs will not resume properly after reset.
The one scenario in bnxt_hwrm_if_change() where the RTNL lock
is already taken in the .ndo_open() context requires the ULP
restart to be deferred to the bnxt_sp_task() workqueue.

The current scheme relies heavily on the RTNL lock for all ULP
operations between the L2 and the RoCE driver. Add a new en_dev_lock
mutex so that the asynchronous ULP_STOP and ULP_START operations
can be serialized with bnxt_register_dev() and bnxt_unregister_dev()
calls without relying on the RTNL lock. The next patch will remove
the RTNL lock from the ULP_STOP and ULP_START calls.

There is no need to call ULP_STOP and ULP_START before and after the
L2 reset in bnxt_reset_task(). This L2 reset is done after detecting
TX timeout, RX ring errors, or VF config changes. The L2 reset does
not affect RoCE since the firmware is not reset and the backing store
is left alone.

Offline self test is a very disruptive operation for RoCE and requires
all active QPs to be destroyed. With a large number of QPs, it can
take a long time to destroy all the QPs and can timeout. Do not allow
ethtool offline self test if the RoCE driver is registered on the
device.

On P5_PLUS chips and later, the NQ rings have subrings for RX and TX
completions respectively. These subrings are passed to the poll
function instead of the base NQ, but each ring carries its own
copy of the software ring statistics.
For stats to be conveniently accessible in __bnxt_poll_work(), the
statistics memory should either be shared between the NQ and its
subrings or the subrings need to be included in the ethtool stats
aggregation logic. This patch opts for the former, because it's more
efficient and less confusing having the software statistics for a
ring exist in a single place.
Before this patch, the counter will not be displayed if the "wrong"
cpr->sw_stats was used to increment a counter.

- do not support cipher BIP-GMAC-128 and BIP-GMAC-256
- support cipher BIP-CMAC-128 and BIP-CMAC-256, except action frame with
action type 'not robust'.
Therefore, to simplify the logic, do not set the IGTK to firmware and
let the encryption of management frames be handled by upper layer.
