e18398e80c Revert "objtool: Support addition to set CFA base" 
Commit 468af56a7b ("objtool: Support addition to set CFA base") was
added as a preparatory patch for arm64 support, but that support never
came.  It triggers a false positive warning on x86, so just revert it
for now.

Fixes the following warning:

  vmlinux.o: warning: objtool: cdce925_regmap_i2c_write+0xdb: stack state mismatch: cfa1=4+120 cfa2=5+40

15def34e26 perf/core: Fix hardlockup failure caused by perf throttle 
commit e050e3f0a7 ("perf: Fix broken interrupt rate throttling")
introduces a change in throttling threshold judgment. Before this,
compare hwc->interrupts and max_samples_per_tick, then increase
hwc->interrupts by 1, but this commit reverses order of these two
behaviors, causing the semantics of max_samples_per_tick to change.
In literal sense of "max_samples_per_tick", if hwc->interrupts ==
max_samples_per_tick, it should not be throttled, therefore, the judgment
condition should be changed to "hwc->interrupts > max_samples_per_tick".

In fact, this may cause the hardlockup to fail, The minimum value of
max_samples_per_tick may be 1, in this case, the return value of
__perf_event_account_interrupt function is 1.
As a result, nmi_watchdog gets throttled, which would stop PMU (Use x86
architecture as an example, see x86_pmu_handle_irq).

a2a83eb40f arm64: kernel: Fix kernel warning when nokaslr is passed to commandline 
'Unknown kernel command line parameters "nokaslr", will be passed to
user space' message is noticed in the dmesg when nokaslr is passed to
the kernel commandline on ARM64 platform. This is because nokaslr param
is handled by early cpufeature detection infrastructure and the parameter
is never consumed by a kernel param handler. Fix this warning by
providing a dummy kernel param handler for nokaslr.

d40a2f5062 RISC-V Devicetrees for v6.4 
Microchip:
 A "fix" for the system controller's regs on PolarFire SoC, adding a
 missing reg property.
 The patch had been sitting there for months and I only re-found it
 recently, so you can guess how much of a "fix" it actually is. It'll
 become needed when the system controller's QSPI gets added in the future,
 but at present there's no urgency as the driver can handle both the
 current and "fixed" versions.
 
 StarFive:
 Basic support for the JH7110 & the associated first-party dev board, the
 VisionFive v2 (in two forms). There's a bunch of dt-bindings required
 for this too, all of which have had input from the DT folk. There's
 enough in this tag to boot to a console w/ an initramfs but little more.
 The SoC supports some of the "new" bit manipulation instructions, which
 is a good test for the recently added Zbb support in the kernel.

    node names with bindings, drop incorrect properties, fix clock-names,
    add missing "ports" node.
 2. Move DP and MIPI phys to PMU node (DTS with binding change).
 3. Drop old MSHC aliases (while adding proper mmc-ddr-1_8v which was

It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

aebe916f9e A few more Qualcomm driver updates for v6.4 
This introduces a new binding and a dedicated driver for the Qualcomm
 Inline-Crypto-Engine (ICE), in order to support a single shared instance
 between SDHCI and UFS, found in recent platforms.
 
 RSC version check is updated to support minor revisions of v3 of the ip
 block, the SMD-RPM interface is transitioned to GFP_ATOMIC to avoid the
 shrinker to kick in underneath the GPU and QCM2290 support is added to
 the SCM binding.

Merge tag 'qcom-drivers-for-6.4-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers

A few more Qualcomm driver updates for v6.4

This introduces a new binding and a dedicated driver for the Qualcomm
Inline-Crypto-Engine (ICE), in order to support a single shared instance
between SDHCI and UFS, found in recent platforms.

RSC version check is updated to support minor revisions of v3 of the ip
block, the SMD-RPM interface is transitioned to GFP_ATOMIC to avoid the
shrinker to kick in underneath the GPU and QCM2290 support is added to
the SCM binding.

2ad91e44e6 perf/arm-cmn: Fix port detection for CMN-700 
When the "extra device ports" configuration was first added, the
additional mxp_device_port_connect_info registers were added around the
existing mxp_mesh_port_connect_info registers. What I missed about
CMN-700 is that it shuffled them around to remove this discontinuity.
As such, tweak the definitions and factor out a helper for reading these
registers so we can deal with this discrepancy easily, which does at
least allow nicely tidying up the callsites. With this we can then also
do the nice thing and skip accesses completely rather than relying on
RES0 behaviour where we know the extra registers aren't defined.

af6c0bd59f arm64: kgdb: Set PSTATE.SS to 1 to re-enable single-step 
Currently only the first attempt to single-step has any effect. After
that all further stepping remains "stuck" at the same program counter
value.

Refer to the ARM Architecture Reference Manual (ARM DDI 0487E.a) D2.12,
PSTATE.SS=1 should be set at each step before transferring the PE to the
'Active-not-pending' state. The problem here is PSTATE.SS=1 is not set
since the second single-step.

After the first single-step, the PE transferes to the 'Inactive' state,
with PSTATE.SS=0 and MDSCR.SS=1, thus PSTATE.SS won't be set to 1 due to
kernel_active_single_step()=true. Then the PE transferes to the
'Active-pending' state when ERET and returns to the debugger by step
exception.

860e1c7f8b io_uring: complete request via task work in case of DEFER_TASKRUN 
So far io_req_complete_post() only covers DEFER_TASKRUN by completing
request via task work when the request is completed from IOWQ.

However, uring command could be completed from any context, and if io
uring is setup with DEFER_TASKRUN, the command is required to be
completed from current context, otherwise wait on IORING_ENTER_GETEVENTS
can't be wakeup, and may hang forever.

The issue can be observed on removing ublk device, but turns out it is
one generic issue for uring command & DEFER_TASKRUN, so solve it in
io_uring core code.

126c6da71f Qualcomm driver updates for v6.4 
The Qualcomm SCM driver will now always clear the download bit, avoiding
 entering download mode on a clean reboot because the bootloader left it
 set. The vmid bitmap passed to qcom_scm_assign_mem() is transitioned to
 a well defined size. SM6375 support is added, and SC8180X,
 QDU1000/QRU1000, IPQ5332 and IPQ9574 compatibles are documented.
 
 GENI gains support for newer hardware with deeper FIFOs.
 
 The BWMON driver is updated to better handle the two register blocks,
 which are not consistent between MSM8998 and newer platforms.
 
 The LLCC driver no longer assumes a fixes stride across the various
 banks, and instead acquire the bank placement from DeviceTree. EDAC
 support for polling is introduced. EDAC support on SDM845 is disabled,
 as its been observed that accessing relevant registers is not permitted
 on most devices.
 
 PMIC GLINK is reworked to support defining which auxiliary children to
 spawn per platform, support for spawning a UCSI child is added and
 SM8450 and SM8550 is introduced.
 
 The RPM power-domain driver is cleaned up by moving and generalizing
 structures that are common between platforms, rather than duplicating
 everything. Macros are replaced with just direct definition of the
 relevant structures. Support for defining parent relationships between
 the power-domains is introduced, like it has been in rpmhpd for a long
 time.
 
 Number of processors has gone up, so max processor count in SMEM
 is bumped again. Error handling in SMSM is cleaned up using
 dev_err_probe().
 
 Socinfo is taught about IPQ9574, QCM2290, QRB2210, QRB4210, SM7150,
 SA8775P and a number of PMICs.

cc4cffc3c1 wifi: brcmfmac: add Cypress 43439 SDIO ids 
Add SDIO ids for use with the muRata 1YN (Cypress CYW43439).
The odd thing about this is that the previous 1YN populated
on M.2 card for evaluation purposes had BRCM SDIO vendor ID,
while the chip populated on real hardware has a Cypress one.
The device ID also differs between the two devices. But they
are both 43439 otherwise, so add the IDs for both.

On-device 1YN (43439), the new one, chip label reads "1YN":
```
/sys/.../mmc_host/mmc2/mmc2:0001 # cat vendor device
0x04b4
0xbd3d
```

EA M.2 evaluation board 1YN (43439), the old one, chip label reads "1YN ES1.4":
```
/sys/.../mmc_host/mmc0/mmc0:0001/# cat vendor device
0x02d0
0xa9a6

3d3b32a6dd RISC-V SoC drivers for v6.4 
Microchip:
 Mailbox controller & client changes for the system controller on
 PolarFire SoC. The controller bits have been acked by Jassi.
 Primarily the changes work around a "hardware" bug (really the system
 controller's software, but it may as well be hardware as customers
 cannot change it) where interrupts are not generated if a service fails.
 The mailbox controller driver is tweaked to use polling, rather than
 interrupt, mode and there are some changes to timeout code required in
 the client driver as a result. There's some opportunistic cleanup that I
 performed while doing the swap too.
 
 Canaan:
 A single fix for some randconfig issues that crop up when !mmu is
 enabled for 32-bit kernels, due to my changes in a previous release that
 swapped out select based entablement of the driver.

RISC-V SoC drivers for v6.4

Microchip:
Mailbox controller & client changes for the system controller on
PolarFire SoC. The controller bits have been acked by Jassi.
Primarily the changes work around a "hardware" bug (really the system
controller's software, but it may as well be hardware as customers
cannot change it) where interrupts are not generated if a service fails.
The mailbox controller driver is tweaked to use polling, rather than
interrupt, mode and there are some changes to timeout code required in
the client driver as a result. There's some opportunistic cleanup that I
performed while doing the swap too.

Canaan:
A single fix for some randconfig issues that crop up when !mmu is
enabled for 32-bit kernels, due to my changes in a previous release that
swapped out select based entablement of the driver.

5395482afa wifi: rtw89: support parameter tables by RFE type 
One chip can have different RFE (RF front end) types which we will judge
at runtime. And, different RFE types may use different RF parameter tables.
Though we didn't really meet this case previously, we are going to meet it
on upcoming chip RTL8851B. So, this commit handles parameter tables for
runtime RFE type.

We now encapsulate rtw89_txpwr_rule_<2/5/6>ghz tables into rtw89_rfe_parms.
Then, each chip defines its default parameter tables, and if needed, it can
configure extra parameter tables by RFE type. Finally we determine runtime
parameter tables by RFE type if one is configured. Otherwise, we use the
default parameter tables.

For now, we just move all settings under default parameter tables. We will
configure parameter tables by RFE types in separate commits afterwards.

ffde7f3476 wifi: rtw89: add firmware format version to backward compatible with older drivers 
In the discuss threads [1] [2], new firmware format break user space
because older drivers can't recognize new firmware format. To avoid this,
the new format will be named rtw89/rtw8852b_fw-1.bin and only new driver
try to load it. Old drivers only load original and understandable firmware
rtw89/rtw8852b_fw.bin.

More, new driver will be still backward compatible with old firmware, so
original firmware can be used by new driver.

If there is newer firmware format is introduced, rtw89/rtw8852b_fw-2.bin
will be given. The same rules will be applied like above. So, we will have
firmware like below in linux-firmware in the future.

  rtw89/rtw8852b_fw-2.bin
  rtw89/rtw8852b_fw-1.bin
  rtw89/rtw8852b_fw.bin

After this patch, MODULE_FIRMWARE() of 8852A/B/C become
  rtw89/rtw8852a_fw.bin

b80ad23a8f wifi: rtw89: use schedule_work to request firmware 
Since we are going to load more than one firmware and some are not
presented or optional, using asynchronous API request_firmware_nowait()
will become complicated. Also, we want to use firmware_request_nowarn()
to avoid warning messages when loading optional files. So, use
schedule_work to be simpler.

To abstract loading a firmware or file, define a struct rtw89_fw_req_info
containing a struct firmware and a completion to ensure this firmware is
loaded completely.

639ec6d635 wifi: rtw89: fw: use generic flow to set/check features 
In early feature bitmap obtained from rtw89_early_fw_feature_recognize(),
the bits needed to check get increased. It's more friendly to work with
RTW89_CHK_FW_FEATURE(). So, we concentrate the flow of iterating FW feature
configures and calling RTW89_SET_FW_FEATURE() for various uses. And then,
we adjust rtw89_early_fw_feature_recognize() for RTW89_CHK_FW_FEATURE().
