Follow the advice of the Documentation/filesystems/sysfs.rst and show()
should only use sysfs_emit() or sysfs_emit_at() when formatting the
value to be returned to user space.

32eb645332 cpufreq: tegra186: Use flexible array to simplify memory allocation
Use flexible array to simplify memory allocation.
It saves some memory, avoids an indirection when reading the 'clusters'
array and removes some LoC.

Detailed explanation:
====================
Knowing that:
  - each devm_ allocation over-allocates 40 bytes for internal needs
  - Some rounding is done by the memory allocator on 8, 16, 32, 64, 96,
    128, 192, 256, 512, 1024, 2048, 4096, 8192 boundaries

and that:
  - sizeof(struct tegra186_cpufreq_data) = 24
  - sizeof(struct tegra186_cpufreq_cluster) = 16

Memory allocations in tegra186_cpufreq_probe() are:
  data:           (24 + 40) = 64 		      => 64 bytes
  data->clusters: (2 * 16 + 40) = 72     => 96 bytes
So a total of 160 bytes are allocated.
56 for the real need, 80 for internal uses and 24 are wasted.

If 'struct tegra186_cpufreq_data' is reordered so that 'clusters' is a
flexible array:
  - it saves one pointer in the structure
  - only one allocation is needed

So, only 96 bytes are allocated:
  16 + 2 * 16 + 40 = 88  => 96 bytes

6286bbb405 cpufreq: apple-soc: Add new driver to control Apple SoC CPU P-states
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.

4370232c72 cpufreq: qcom-hw: Add CPU clock provider support
Qcom CPUFreq hardware (EPSS/OSM) controls clock and voltage to the CPU
cores. But this relationship is not represented with the clk framework
so far.

So, let's make the qcom-cpufreq-hw driver a clock provider. This makes the
clock producer/consumer relationship cleaner and is also useful for CPU
related frameworks like OPP to know the frequency at which the CPUs are
running.

The clock frequency provided by the driver is for each frequency domain.
We cannot get the frequency of each CPU core because, not all platforms
support per-core DCVS feature.

Also the frequency supplied by the driver is the actual frequency that
comes out of the EPSS/OSM block after the DCVS operation. This frequency is
not same as what the CPUFreq framework has set but it is the one that gets
supplied to the CPUs after throttling by LMh.

202e683df3 cpufreq: amd-pstate: add amd-pstate driver parameter for mode selection
When the amd_pstate driver is built-in users still need a method to be
able enable or disable it depending upon their circumstance.
Add support for an early parameter to do this.

There is some performance degradation on a number of ASICs in the
passive mode. This performance issue was originally discovered in
shared memory systems but it has been proven that certain workloads
on MSR systems also suffer performance issues.
Set the amd-pstate driver as disabled by default to temporarily
mitigate the performance problem.

 1) with `amd_pstate=disable`, pstate driver will be disabled to load at
    kernel booting.

 2) with `amd_pstate=passive`, pstate driver will be enabled and loaded
    as non-autonomous working mode supported in the low-level power
    management firmware.

 3) If neither parameter is specified, the driver will be disabled by
    default to avoid triggering performance regressions in certain ASICs

919f455769 cpufreq: amd-pstate: cpufreq: amd-pstate: reset MSR_AMD_PERF_CTL register at init
MSR_AMD_PERF_CTL is guaranteed to be 0 on a cold boot. However, on a
kexec boot, for instance, it may have a non-zero value (if the cpu was
in a non-P0 Pstate).  In such cases, the cores with non-P0 Pstates at
boot will never be pushed to P0, let alone boost frequencies.

Kexec is a common workflow for reboot on Linux and this creates a
regression in performance. Fix it by explicitly setting the
MSR_AMD_PERF_CTL to 0 during amd_pstate driver init.

94eedf3dde tracing: Fix race where eprobes can be called before the event
The flag that tells the event to call its triggers after reading the event
is set for eprobes after the eprobe is enabled. This leads to a race where
the eprobe may be triggered at the beginning of the event where the record
information is NULL. The eprobe then dereferences the NULL record causing
a NULL kernel pointer bug.

Test for a NULL record to keep this from happening.

7fc961cf7f iommu/vt-d: Set SRE bit only when hardware has SRS cap
SRS cap is the hardware cap telling if the hardware IOMMU can support
requests seeking supervisor privilege or not. SRE bit in scalable-mode
PASID table entry is treated as Reserved(0) for implementation not
supporting SRS cap.

Checking SRS cap before setting SRE bit can avoid the non-recoverable
fault of "Non-zero reserved field set in PASID Table Entry" caused by
setting SRE bit while there is no SRS cap support. The fault messages
look like below:

 DMAR: DRHD: handling fault status reg 2
 DMAR: [DMA Read NO_PASID] Request device [00:0d.0] fault addr 0x1154e1000
       [fault reason 0x5a]

242b0aaeab iommu/vt-d: Preset Access bit for IOVA in FL non-leaf paging entries
The A/D bits are preseted for IOVA over first level(FL) usage for both
kernel DMA (i.e, domain typs is IOMMU_DOMAIN_DMA) and user space DMA
usage (i.e., domain type is IOMMU_DOMAIN_UNMANAGED).

Presetting A bit in FL requires to preset the bit in every related paging
entries, including the non-leaf ones. Otherwise, hardware may treat this
as an error. For example, in a case of ECAP_REG.SMPWC==0, DMA faults might
occur with below DMAR fault messages (wrapped for line length) dumped.

 DMAR: DRHD: handling fault status reg 2

63c8c0d7dc Merge tag 'driver-core-6.1-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core fixes from Greg KH:
 "Here are two small driver core fixes for 6.1-rc6:

   - utsname fix, this one should already be in your tree as it came
     from a different tree earlier.

   - kernfs bugfix for a much reported syzbot report that seems to keep
     getting triggered.

  Both of these have been in linux-next for a while with no reported
  issues"
