Static calls invocations aren't well supported from module __init and
__exit functions. Especially the static call from cleanup_trusted() led
to a crash on x86 kernel with CONFIG_DEBUG_VIRTUAL=y.
However, the usage of static call invocations for trusted_key_init()
and trusted_key_exit() don't add any value from either a performance or
security perspective. Hence switch to use indirect function calls instead.
Note here that although it will fix the current crash report, ultimately
the static call infrastructure should be fixed to either support its
future usage from module __init and __exit functions or not.

Pull irq fixes from Thomas Gleixner:
"A set of updates for interrupt chip drivers:
- Fix the fail of the Qualcomm PDC driver on v3.2 hardware which is
caused by a control bit being moved to a different location
- Update the SM8150 device tree PDC resource so the version register
can be read
- Make the Renesas RZG2L driver correct for interrupts which are
outside of the LSB in the TSSR register by using the proper macro
for calculating the mask
- Document the Renesas RZ2GL device tree binding correctly and update
them for a few devices which faul to boot otherwise
- Use the proper accessor in the RZ2GL driver instead of blindly
dereferencing an unchecked pointer
- Make GICv3 handle the dma-non-coherent attribute correctly
- Ensure that all interrupt controller nodes on RISCV are marked as
initialized correctly
Maintainer changes:
- Add a new entry for GIC interrupt controllers and assign Marc
Zyngier as the maintainer
- Remove Marc Zyngier from the core and driver maintainer entries as
he is burried in work and short of time to handle that.
Thanks to Marc for all the great work he has done in the past couple
of years!
Also note that commit 5873d380f4c0 ("irqchip/qcom-pdc: Add support for
v3.2 HW") has a incorrect SOB chain.
The real author is Neil. His patch was posted by Dmitry once and Neil
picked it up from the list and reposted it with the bogus SOB chain.
Not a big deal, but worth to mention. I wanted to fix that up, but
then got distracted and Marc piled more changes on top. So I decided
to leave it as is instead of rebasing world"

This reverts commit 5f521494cc73520ffac18ede0758883b9aedd018.
The patch breaks mounts with security mount options like
$ mount -o context=system_u:object_r:root_t:s0 /dev/sdX /mn
mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdX, missing codepage or helper program, ...
We cannot reject all unknown options in btrfs_parse_subvol_options() as
intended, the security options can be present at this point and it's not
possible to enumerate them in a future proof way. This means unknown
mount options are silently accepted like before when the filesystem is
mounted with either -o subvol=/path or as followup mounts of the same
device.

Commit 1e66220948df8 ("net/mlx5e: Update rx ring hw mtu upon each rx-fcs
flag change") seems to have accidentally inverted the logic added in
commit 0bc73ad46a76 ("net/mlx5e: Mutually exclude RX-FCS and
RX-port-timestamp").
The impact of this is a little unclear since it seems the FCS scattered
with RX-FCS is (usually?) correct regardless.

The driver might pull connectors which weren't submitted by
user-space into the atomic state. For instance,
intel_dp_mst_atomic_master_trans_check() pulls in connectors
sharing the same DP-MST stream. However, if the connector is
unregistered, this later fails with:
[ 559.425658] i915 0000:00:02.0: [drm:drm_atomic_helper_check_modeset] [CONNECTOR:378:DP-7] is not registered
Skip the unregistered connector check to allow user-space to turn
off connectors one-by-one.

When the SMC protocol is built into the kernel proper while ISM is
configured to be built as module, linking the kernel fails due to
unresolved dependencies out of net/smc/smc_ism.o to
ism_get_smcd_ops, ism_register_client, and ism_unregister_client
as reported via the linux-next test automation (see link).
This however is a bug introduced a while ago.
Correct the dependency list in ISM's and SMC's Kconfig to reflect the
dependencies that are actually inverted. With this you cannot build a
kernel with CONFIG_SMC=y and CONFIG_ISM=m. Either ISM needs to be 'y',
too - or a 'n'. That way, SMC can still be configured on non-s390
architectures that do not have (nor need) an ISM driver.

The sta_himax83102 panel sometimes shows abnormally flickering
horizontal lines. The front gate output will precharge the X point of
the next pole circuit before TP(TouchPanel Enable) term starts, and wait
until the end of the TP term to resume the CLK. For this reason, the X
point must be maintained during the TP term. In abnormal case, we
measured a slight leakage at point X. This because during the TP term,
the GPW does not fully pull the VGL low, causing the TFT to not be
closed tightly.
To fix this, we completely pull GPW to VGL before entering the TP term.
This will ensure that the TFT is closed tightly and prevent the abnormal
display.

Indicate next PN update using update_pn flag in macsec_context.
Offloaded MACsec implementations does not know whether or not the
MACSEC_SA_ATTR_PN attribute was passed for an SA update and assume
that next PN should always updated, but this is not always true.
The PN can be reset to its initial value using the following command:
$ ip macsec set macsec0 tx sa 0 off #octeontx2-pf case
Or, the update PN command will succeed even if the driver does not support
PN updates.
$ ip macsec set macsec0 tx sa 0 pn 1 on #mscc phy driver case
Comparing the initial PN with the new PN value is not a solution. When
the user updates the PN using its initial value the command will
succeed, even if the driver does not support it. Like this:
$ ip macsec add macsec0 tx sa 0 pn 1 on key 00 \

TPS25750 controller requires a binary to be loaded with a configuration
binary by an EEPROM or a host.
Appling a patch bundling using a host is implemented based on the flow
diagram pg.62 in TPS25750 host interface manual.
https://www.ti.com/lit/ug/slvuc05a/slvuc05a.pdf
The flow diagram can be summarized as following:
- Start the patch loading sequence with patch bundle information by
executing PBMs
- Write the whole patch at once
- When writing the patch fails, execute PBMe which instructs the PD controller
to end the patching process
- After writing the patch successfully, execute PBMc which verifies the patch
integrity and applies the patch internally
- Wait for the device to switch into APP mode (normal operation)
The execuation flow diagram polls the events register and then polls the
corresponding register related to the event as well before advancing to the next
state. Polling the events register is a redundant step, in this implementation
only the corresponding register related to the event is polled.
Adding tps25750 support, the followings are being taken care of:
- Implement applying patch flow.
- When an EEPROM is present, tps25750 loads the binary configuration from
EEPROM. Hence, all we need to do is wait for the device to switch to APP
mode.
- Dead battery flag is cleared after switching tps25750 to APP mode so the
PD controller becomes fully functional.
- Add port registration as tps25750 doesn't have system configuration register
to get dr/pr of the current applied binary configuration. Get data role from
the device node and power role from PD status register.
- tps25750 event registers structure is different than tps6598x's,
tps25750 has 11 bytes of events which are read at once where
tps6598x has two event registers of 8 bytes each which are read
separately. Likewise MASK event registers. Also, not all events
are supported in both devices. Create a new handler to accommodate
tps25750 interrupt.
- Enable sleep mode so the device enters sleep state when idling.
- When the current mode is PTCH, enable tps25750 by loading a
configuration patch that switches the device into APP mode.
- Add resume and suspend pm for tps25750.

Commit ff48b37802e5 ("scsi: Do not attempt to rescan suspended devices")
modified scsi_rescan_device() to avoid attempting rescanning a suspended
device. However, the modification added a check to verify that a SCSI
device is in the running state without checking if the device request
queue (in the case of block device) is also running, thus allowing the
exectuion of internal requests. Without checking the device request
queue, commit ff48b37802e5 fix is incomplete and deadlocks on resume can
still happen. Use blk_queue_pm_only() to check if the device request

fit3 protocol driver does not support accessing IDE control registers
(device control/altstatus). The DOS driver does not use these registers
either (as observed from DOSEMU trace). But the HW seems to be capable
of accessing these registers - I simply tried bit 3 and it works!
The control register is required to properly reset ATAPI devices or
they will be detected only once (after a power cycle).
Tested with EXP Computer CD-865 with MC-1285B EPP cable and
TransDisk 3000.

Some parallel adapters (e.g. EXP Computer MC-1285B EPP Cable) return
bogus values when there's no master device present. This can cause
reset to fail, preventing the lone slave device (such as EXP Computer
CD-865) from working.
Add custom version of wait_after_reset that ignores master failure when
a slave device is present. The custom version is also needed because
the generic ata_sff_wait_after_reset uses direct port I/O for slave
device detection.

Ifcfg config file support in NetworkManger is deprecated. This patch
provides support for the new keyfile config format for connection
profiles in NetworkManager. The patch modifies the hv_kvp_daemon code
to generate the new network configuration in keyfile
format(.ini-style format) along with a ifcfg format configuration.
The ifcfg format configuration is also retained to support easy
backward compatibility for distro vendors. These configurations are
stored in temp files which are further translated using the
hv_set_ifconfig.sh script. This script is implemented by individual
distros based on the network management commands supported.
For example, RHEL's implementation could be found here:
https://gitlab.com/redhat/centos-stream/src/hyperv-daemons/-/blob/c9s/hv_set_ifconfig.sh
Debian's implementation could be found here:
https://github.com/endlessm/linux/blob/master/debian/cloud-tools/hv_set_ifconfig
The next part of this support is to let the Distro vendors consume
these modified implementations to the new configuration format.
Tested-on: Rhel9(Hyper-V, Azure)(nm and ifcfg files verified)

The verifier, as part of check_return_code(), verifies that async
callbacks such as from e.g. timers, will return 0. It does this by
correctly checking that R0->var_off is in tnum_const(0), which
effectively checks that it's in a range of 0. If this condition fails,
however, it prints an error message which says that the value should
have been in (0x0; 0x1). This results in possibly confusing output such
as the following in which an async callback returns 1:
At async callback the register R0 has value (0x1; 0x0) should have been in (0x0; 0x1)
The fix is easy -- we should just pass the tnum_const(0) as the correct
range to verbose_invalid_scalar(), which will then print the following:
At async callback the register R0 has value (0x1; 0x0) should have been in (0x0; 0x0)

are created and managed by the userspace as GEM buffers. Surfaces
grab only a ttm reference which means that the gem object can
be deleted underneath us, especially in cases where prime buffer
export is used.
Make sure that all userspace surfaces which are backed by gem objects

One PID may appear multiple times in a preloaded pidlist.
(Possibly due to PID recycling but we have reports of the same
task_struct appearing with different PIDs, thus possibly involving
transfer of PID via de_thread().)
Because v1 seq_file iterator uses PIDs as position, it leads to
a message:
> seq_file: buggy .next function kernfs_seq_next did not update position index
Conservative and quick fix consists of removing duplicates from `tasks`
file (as opposed to removing pidlists altogether). It doesn't affect
correctness (it's sufficient to show a PID once), performance impact
would be hidden by unconditional sorting of the pidlist already in place
(asymptotically).

The RISC-V BPF uses a5 for BPF return values, which are zero-extended,
whereas the RISC-V ABI uses a0 which is sign-extended. In other words,
a5 and a0 can differ, and are used in different context.
The BPF trampoline are used for both BPF programs, and regular kernel
functions.
Make sure that the RISC-V BPF trampoline saves, and restores both a0
and a5.

The RISC-V architecture does not expose sub-registers, and hold all
32-bit values in a sign-extended format [1] [2]:
| The compiler and calling convention maintain an invariant that all
| 32-bit values are held in a sign-extended format in 64-bit
| registers. Even 32-bit unsigned integers extend bit 31 into bits
| 63 through 32. Consequently, conversion between unsigned and
| signed 32-bit integers is a no-op, as is conversion from a signed
| 32-bit integer to a signed 64-bit integer.
While BPF, on the other hand, exposes sub-registers, and use
zero-extension (similar to arm64/x86).
This has led to some subtle bugs, where a BPF JITted program has not
sign-extended the a0 register (return value in RISC-V land), passed
the return value up the kernel, e.g.:
| int from_bpf(void);
|
| long foo(void)
| {
| return from_bpf();
| }
Here, a0 would be 0xffff_ffff, instead of the expected
0xffff_ffff_ffff_ffff.
Internally, the RISC-V JIT uses a5 as a dedicated register for BPF
return values.
Keep a5 zero-extended, but explicitly sign-extend a0 (which is used
outside BPF land). Now that a0 (RISC-V ABI) and a5 (BPF ABI) differs,
a0 is only moved to a5 for non-BPF native calls (BPF_PSEUDO_CALL).

irq1_edge_low_force_override[]
The TongFang GM6BGEQ, GM6BG5Q and GM6BG0Q are 3 GPU variants of a TongFang
barebone design which is sold under various brand names.
The ACPI IRQ override for the keyboard IRQ must be used on these AMD Zen
laptops in order for the IRQ to work.
Adjust the pcspecialist_laptop[] DMI match table for this:
1. Drop the sys-vendor match from the existing PCSpecialist Elimina Pro 16
entry for the GM6BGEQ (RTX3050 GPU) model so that it will also match
the laptop when sold by other vendors such as hyperbook.pl.
2. Add board-name matches for the GM6BG5Q (RTX4050) and GM6B0Q (RTX4060)
models.
Note the .ident values of the dmi_system_id structs are left unset
since these are not used.
