Pull probe fixes from Masami Hiramatsu:
- fprobe: Add a comment why fprobe will be skipped if another kprobe is
running in fprobe_kprobe_handler().
- probe-events: Fix some issues related to fetch-arguments:
- Fix double counting of the string length for user-string and
symstr. This will require longer buffer in the array case.
- Fix not to count error code (minus value) for the total used
length in array argument. This makes the total used length
shorter.
- Fix to update dynamic used data size counter only if fetcharg uses
the dynamic size data. This may mis-count the used dynamic data
size and corrupt data.
- Revert "tracing: Add "(fault)" name injection to kernel probes"
because that did not work correctly with a bug, and we agreed the
current '(fault)' output (instead of '"(fault)"' like a string)
explains what happened more clearly.
- Fix to record 0-length (means fault access) data_loc data in fetch
function itself, instead of store_trace_args(). If we record an
array of string, this will fix to save fault access data on each
entry of the array correctly.

fprobes: Add a comment why fprobe_kprobe_handler exits if kprobe is running
The affected lines were resulting in a NULL pointer dereference on our
platform because the device tree contained the following list of
compatible strings:
power-sensor@40 {
compatible = "ti,ina232", "ti,ina231";
...
};
Since the driver doesn't declare a compatible string "ti,ina232", the OF
matching succeeds on "ti,ina231". But the I2C device ID info is
populated via the first compatible string, cf. modalias population in
of_i2c_get_board_info(). Since there is no "ina232" entry in the legacy
I2C device ID table either, the struct i2c_device_id *id pointer in the
probe function is NULL.
Fix this by using the already populated type variable instead, which
points to the proper driver data. Since the name is also wanted, add a
generic one to the ina2xx_config table.

AC excitation enable feature exposed to user on AD7192, allowing a bit
which should be 0 to be set. This feature is specific only to AD7195. AC
excitation attribute moved accordingly.
In the AD7195 documentation, the AC excitation enable bit is on position
22 in the Configuration register. ACX macro changed to match correct
register and bit.
Note that the fix tag is for the commit that moved the driver out of

Currently, read/write_page_hwecc() and read/write_page_raw() are not
aligned: there is a mismatch in the OOB bytes which are not
read/written at the same offset in both cases (raw vs. hwecc).
This is a real problem when relying on the presence of the Page
Addresses (PA) when using the NAND chip as a boot device, as the
BootROM expects additional data in the OOB area at specific locations.
Rockchip boot blocks are written per 4 x 512 byte sectors per page.
Each page with boot blocks must have a page address (PA) pointer in OOB
to the next page. Pages are written in a pattern depending on the NAND chip ID.
Generate boot block page address and pattern for hwecc in user space
and copy PA data to/from the already reserved last 4 bytes before ECC
in the chip->oob_poi data layout.
Align the different helpers. This change breaks existing jffs2 users.

Rockchip boot blocks are written per 4 x 512 byte sectors per page.
Each page with boot blocks must have a page address (PA) pointer in OOB
to the next page.
The currently advertised free OOB area starts at offset 6, like
if 4 PA bytes were located right after the BBM. This is wrong as the
PA bytes are located right before the ECC bytes.
Fix the layout by allowing access to all bytes between the BBM and the
PA bytes instead of reserving 4 bytes right after the BBM.

Pull x86 CFI fixes from Peter Zijlstra:
"Fix kCFI/FineIBT weaknesses
The primary bug Alyssa noticed was that with FineIBT enabled function
prologues have a spurious ENDBR instruction:
__cfi_foo:
endbr64
subl $hash, %r10d
jz 1f
ud2
nop
1:
foo:
endbr64 <--- *sadface*
This means that any indirect call that fails to target the __cfi
symbol and instead targets (the regular old) foo+0, will succeed due
to that second ENDBR.
Fixing this led to the discovery of a single indirect call that was
still doing this: ret_from_fork(). Since that's an assembly stub the
compiler would not generate the proper kCFI indirect call magic and it
would not get patched.
Brian came up with the most comprehensive fix -- convert the thing to
C with only a very thin asm wrapper. This ensures the kernel thread
boostrap is a proper kCFI call.
While discussing all this, Kees noted that kCFI hashes could/should be
poisoned to seal all functions whose address is never taken, further
limiting the valid kCFI targets -- much like we already do for IBT.
So what was a 'simple' observation and fix cascaded into a bunch of

For those PMU system registers defined in sys_reg_descs[], use macro
PMU_SYS_REG() / PMU_PMEVCNTR_EL0 / PMU_PMEVTYPER_EL0 to define them, and
later two macros call macro PMU_SYS_REG() actually.
Currently the input parameter of PMU_SYS_REG() is another macro which is
calculation formula of the value of system registers, so for example, if
we want to "SYS_PMINTENSET_EL1" as the name of sys register, actually
the name we get is as following:
(((3) << 19) | ((0) << 16) | ((9) << 12) | ((14) << 8) | ((1) << 5))
The name of system register is used in some tracepoints such as
trace_kvm_sys_access(), if not set correctly, we need to analyze the
inaccurate name to get the exact name (which also is inconsistent with
other system registers), and also the inaccurate name occupies more space.
To fix the issue, use the name as a input parameter of PMU_SYS_REG like
MTE_REG or EL2_REG.

The PMU event ID varies from 10 to 16 bits, depending on the PMU
version. If the PMU only supports 10 bits of event ID, bits [15:10] of
the evtCount field behave as RES0.
While the actual PMU emulation code gets this right (i.e. RES0 bits are
masked out when programming the perf event), the sysreg emulation writes
an unmasked value to the in-memory cpu context. The net effect is that
guest reads and writes of PMEVTYPER<n>_EL0 will see non-RES0 behavior in
the reserved bits of the field.
As it so happens, kvm_pmu_set_counter_event_type() already writes a
masked value to the in-memory context that gets overwritten by
access_pmu_evtyper(). Fix the issue by removing the unnecessary (and
incorrect) register write in access_pmu_evtyper().

We have seen rare IO stalls as follows:
* blk_mq_plug_issue_direct() is entered with an mq_list containing two
requests.
* For the first request, it sets last == false and enters the driver's
queue_rq callback.
* The driver queue_rq callback indirectly calls schedule() which calls
blk_flush_plug(). This may happen if the driver has the
BLK_MQ_F_BLOCKING flag set and is allowed to sleep in ->queue_rq.
* blk_flush_plug() handles the remaining request in the mq_list. mq_list
is now empty.
* The original call to queue_rq resumes (with last == false).
* The loop in blk_mq_plug_issue_direct() terminates because there are no
remaining requests in mq_list.
The IO is now stalled because the last request submitted to the driver
had last == false and there was no subsequent call to commit_rqs().
Fix this by returning early in blk_mq_flush_plug_list() if rq_count is 0
which it will be in the recursive case, rather than checking if the
mq_list is empty. At the same time, adjust one of the callers to skip
the mq_list empty check as it is not necessary.

The build failure reported in [1] occurred because commit <9fc96c7c19df>
("selftests: error out if kernel header files are not yet built") added
a new "kernel_header_files" dependency to "all", and that triggered
another, pre-existing problem. Specifically, the arm64 selftests
override the emit_tests target, and that override improperly declares
itself to depend upon the "all" target.
This is a problem because the "emit_tests" target in lib.mk was not
intended to be overridden. emit_tests is a very simple, sequential build
target that was originally invoked from the "install" target, which in
turn, depends upon "all".
That approach worked for years. But with 9fc96c7c19 in place,
emit_tests failed, because it does not set up all of the elaborate
things that "install" does. And that caused the new
"kernel_header_files" target (which depends upon $(KBUILD_OUTPUT) being
correct) to fail.
Some detail: The "all" target is .PHONY. Therefore, each target that
depends on "all" will cause it to be invoked again, and because
dependencies are managed quite loosely in the selftests Makefiles, many
things will run, even "all" is invoked several times in immediate
succession. So this is not a "real" failure, as far as build steps go:
everything gets built, but "all" reports a problem when invoked a second
time from a bad environment.
To fix this, simply remove the unnecessary "all" dependency from the
overridden emit_tests target. The dependency is still effectively
honored, because again, invocation is via "install", which also depends
upon "all".
An alternative approach would be to harden the emit_tests target so that
it can depend upon "all", but that's a lot more complicated and hard to
get right, and doesn't seem worth it, especially given that emit_tests
should probably not be overridden at all.

PM: hibernate: Fix writing maj:min to /sys/power/resume
Merge a PM QoS fix and a hibernation fix for 6.5-rc2.
- Unbreak the /sys/power/resume interface after recent changes (Azat
Khuzhin).
- Allow PM_QOS_DEFAULT_VALUE to be used with frequency QoS (Chungkai
Yang).

PM: QoS: Restore support for default value on frequency QoS
The current code assumes that the CSC3551(multiple cs35l41) always have
its interrupt pin connected to GPIO thus the IRQ can be acquired with
acpi_dev_gpio_irq_get. However on some newer laptop models this is no
longer the case as they have the CSC3551's interrupt pin connected to
APIC. This causes smi_i2c_probe to fail on these machines.
To support these machines, a new macro IRQ_RESOURCE_AUTO was introduced
for cs35l41 smi_node, and smi_get_irq function was modified so it tries
to get GPIO irq resource first and if failed, tries to get
APIC irq resource for cs35l41.
This patch affects only the cs35l41's probing and brings no negative
influence on machines that indeed have the cs35l41's interrupt pin
connected to GPIO.

Since commit 6624e780a5 ("ice: split ice_vsi_setup into smaller
functions") ice_vsi_release does things twice. There is unregister
netdev which is unregistered in ice_deinit_eth also.
It also unregisters the devlink_port twice which is also unregistered
in ice_deinit_eth(). This double deregistration is hidden because
devl_port_unregister ignores the return value of xa_erase.

When the number of responses with status of STATUS_IO_TIMEOUT
exceeds a specified threshold (NUM_STATUS_IO_TIMEOUT), we reconnect
the connection. But we do not return the mid, or the credits
returned for the mid, or reduce the number of in-flight requests.
This bug could result in the server->in_flight count to go bad,
and also cause a leak in the mids.
This change moves the check to a few lines below where the
response is decrypted, even of the response is read from the
transform header. This way, the code for returning the mids
can be reused.
Also, the cifs_reconnect was reconnecting just the transport
connection before. In case of multi-channel, this may not be
what we want to do after several timeouts. Changed that to
reconnect the session and the tree too.
Also renamed NUM_STATUS_IO_TIMEOUT to a more appropriate name
MAX_STATUS_IO_TIMEOUT.
