ASoC: imx-pcm-rpmsg: Register different platform drivers
This patch can register different ASoC platform drivers if there are
several rpmsg channels. Thus sound cards based on different rpmsg
channels can link to their respective platform drivers. Besides, the
name of driver is equal to the name of rpmsg channel.

ASoC: imx-audio-rpmsg: Create rpmsg channel for MICFIL
Rpmsg channel for MICFIL can also be created through rpmsg name service
announcement. If this driver is probed, Cortex-A can access MICFIL
which is actually controlled by Cortex-M through rpmsg channel for
MICFIL. This driver also helps register ASoC platform device thus use
of PLATFORM_DEVID_AUTO macro in API can automatically create device for
each rpmsg channel.

ASoC: dt-bindings: fsl_rpmsg: Add a property to assign the rpmsg channel
Add a string property to assign the rpmsg channel this sound card sits
on. This property can be omitted if there is only one sound card and it
sits on "rpmsg-audio-channel".

Pull more random number generator updates from Jason Donenfeld:
 "This time with some large scale treewide cleanups.

  The intent of this pull is to clean up the way callers fetch random
  integers. The current rules for doing this right are:

   - If you want a secure or an insecure random u64, use get_random_u64()

   - If you want a secure or an insecure random u32, use get_random_u32()

     The old function prandom_u32() has been deprecated for a while
     now and is just a wrapper around get_random_u32(). Same for
     get_random_int().

   - If you want a secure or an insecure random u16, use get_random_u16()

   - If you want a secure or an insecure random u8, use get_random_u8()

   - If you want secure or insecure random bytes, use get_random_bytes().

     The old function prandom_bytes() has been deprecated for a while
     now and has long been a wrapper around get_random_bytes()

   - If you want a non-uniform random u32, u16, or u8 bounded by a
     certain open interval maximum, use prandom_u32_max()

     I say "non-uniform", because it doesn't do any rejection sampling
     or divisions. Hence, it stays within the prandom_*() namespace, not
     the get_random_*() namespace.

     I'm currently investigating a "uniform" function for 6.2. We'll see
     what comes of that.

  By applying these rules uniformly, we get several benefits:

   - By using prandom_u32_max() with an upper-bound that the compiler
     can prove at compile-time is ≤65536 or ≤256, internally
     get_random_u16() or get_random_u8() is used, which wastes fewer
     batched random bytes, and hence has higher throughput.

   - By using prandom_u32_max() instead of %, when the upper-bound is
     not a constant, division is still avoided, because
     prandom_u32_max() uses a faster multiplication-based trick instead.

   - By using get_random_u16() or get_random_u8() in cases where the
     return value is intended to indeed be a u16 or a u8, we waste fewer
     batched random bytes, and hence have higher throughput.

  This series was originally done by hand while I was on an airplane
  without Internet. Later, Kees and I worked on retroactively figuring
  out what could be done with Coccinelle and what had to be done
  manually, and then we split things up based on that.

  So while this touches a lot of files, the actual amount of code that's
  hand fiddled is comfortably small"

8636df94ec perf tools changes for v6.1: 2nd batch
- Use BPF CO-RE (Compile Once, Run Everywhere) to support old kernels
   when using bperf (perf BPF based counters) with cgroups.
 
 - Support HiSilicon PCIe Performance Monitoring Unit (PMU), that
   monitors bandwidth, latency, bus utilization and buffer occupancy.
 
   Documented in Documentation/admin-guide/perf/hisi-pcie-pmu.rst.
 
 - User space tasks can migrate between CPUs, so when tracing selected
   CPUs, system-wide sideband is still needed, fix it in the setup of
   Intel PT on hybrid systems.
 
 - Fix metricgroups title message in 'perf list', it should state that
   the metrics groups are to be used with the '-M' option, not '-e'.
 
 - Sync the msr-index.h copy with the kernel sources, adding support
   for using "AMD64_TSC_RATIO" in filter expressions in 'perf trace' as
   well as decoding it when printing the MSR tracepoint arguments.
 
 - Fix program header size and alignment when generating a JIT ELF
   in 'perf inject'.
 
 - Add multiple new Intel PT 'perf test' entries, including a jitdump one.
 
 - Fix the 'perf test' entries for 'perf stat' CSV and JSON output when
   running on PowerPC due to an invalid topology number in that arch.
 
 - Fix the 'perf test' for arm_coresight failures on the ARM Juno system.
 
 - Fix the 'perf test' attr entry for PERF_FORMAT_LOST, adding this option
   to the or expression expected in the intercepted perf_event_open() syscall.
 
 - Add missing condition flags ('hs', 'lo', 'vc', 'vs') for arm64 in the 'perf
   annotate' asm parser.
 
 - Fix 'perf mem record -C' option processing, it was being chopped up
   when preparing the underlying 'perf record -e mem-events' and thus being
   ignored, requiring using '-- -C CPUs' as a workaround.
 
 - Improvements and tidy ups for 'perf test' shell infra.
 
 - Fix Intel PT information printing segfault in uClibc, where a NULL
   format was being passed to fprintf.

2fcd8f108f This is the final part of the clk patches for this merge window.
The clk rate range series needed another week to fully bake. Maxime
 fixed the bug that broke clk notifiers and prevented this from being
 included in the first pull request. He also added a unit test on top to
 make sure it doesn't break so easily again. The majority of the series
 fixes up how the clk_set_rate_*() APIs work, particularly around when
 the rate constraints are dropped and how they move around when
 reparenting clks. Overall it's a much needed improvement to the clk rate
 range APIs that used to be pretty broken if you looked sideways.
 
 Beyond the core changes there are a few driver fixes for a compilation
 issue or improper data causing clks to fail to register or have the
 wrong parents. These are good to get in before the first -rc so that the
 system actually boots on the affected devices.

valid cpu range") is broken.  Obviously that patch hits WARN_ON_ONCE()
when e.g.  reading /proc/cpuinfo because passing "cpu + 1" instead of
"cpu" will trivially hit cpu == nr_cpumask_bits condition.

Although syzbot found this problem in linux-next.git on 2022/09/27 [2],
this problem was not fixed immediately.  As a result, that patch was
sent to linux.git before the patch author recognizes this problem, and
syzbot started failing to test changes in linux.git since 2022/10/10
[3].

Andrew Jones proposed a fix for x86 and riscv architectures [4].  But
[2] and [5] indicate that affected locations are not limited to arch
code.  More delay before we find and fix affected locations, less tested
kernel (and more difficult to bisect and fix) before release.

We should have inspected and fixed basically all cpumask users before
applying that patch.  We should not crash kernels in order to ask
existing cpumask users to update their code, even if limited to
CONFIG_DEBUG_PER_CPU_MAPS=y case.

0a6de78cff lib/Kconfig.debug: Add check for non-constant .{s,u}leb128 support to DWARF5
When building with a RISC-V kernel with DWARF5 debug info using clang
and the GNU assembler, several instances of the following error appear:

  /tmp/vgettimeofday-48aa35.s:2963: Error: non-constant .uleb128 is not supported

Dumping the .s file reveals these .uleb128 directives come from
.debug_loc and .debug_ranges:

  .Ldebug_loc0:
          .byte   4                               # DW_LLE_offset_pair
          .uleb128 .Lfunc_begin0-.Lfunc_begin0    #   starting offset
          .uleb128 .Ltmp1-.Lfunc_begin0           #   ending offset
          .byte   1                               # Loc expr size
          .byte   90                              # DW_OP_reg10
          .byte   0                               # DW_LLE_end_of_list

  .Ldebug_ranges0:
          .byte   4                               # DW_RLE_offset_pair
          .uleb128 .Ltmp6-.Lfunc_begin0           #   starting offset
          .uleb128 .Ltmp27-.Lfunc_begin0          #   ending offset
          .byte   4                               # DW_RLE_offset_pair
          .uleb128 .Ltmp28-.Lfunc_begin0          #   starting offset
          .uleb128 .Ltmp30-.Lfunc_begin0          #   ending offset
          .byte   0                               # DW_RLE_end_of_list

There is an outstanding binutils issue to support a non-constant operand
to .sleb128 and .uleb128 in GAS for RISC-V but there does not appear to
be any movement on it, due to concerns over how it would work with
linker relaxation.

To avoid these build errors, prevent DWARF5 from being selected when
using clang and an assembler that does not have support for these symbol
deltas, which can be easily checked in Kconfig with as-instr plus the
small test program from the dwz test suite from the binutils issue.

e36ce448a0 mm/slab: use kmalloc_node() for off slab freelist_idx_t array allocation
After commit d6a71648db ("mm/slab: kmalloc: pass requests larger than
order-1 page to page allocator"), SLAB passes large ( > PAGE_SIZE * 2)
requests to buddy like SLUB does.

SLAB has been using kmalloc caches to allocate freelist_idx_t array for
off slab caches. But after the commit, freelist_size can be bigger than
KMALLOC_MAX_CACHE_SIZE.

Instead of using pointer to kmalloc cache, use kmalloc_node() and only
check if the kmalloc cache is off slab during calculate_slab_order().
If freelist_size > KMALLOC_MAX_CACHE_SIZE, no looping condition happens
as it allocates freelist_idx_t array directly from buddy.

e3e9463414 smb3: improve SMB3 change notification support
Change notification is a commonly supported feature by most servers,
but the current ioctl to request notification when a directory is
changed does not return the information about what changed
(even though it is returned by the server in the SMB3 change
notify response), it simply returns when there is a change.

This ioctl improves upon CIFS_IOC_NOTIFY by returning the notify
information structure which includes the name of the file(s) that
changed and why. See MS-SMB2 2.2.35 for details on the individual
filter flags and the file_notify_information structure returned.

To use this simply pass in the following (with enough space
to fit at least one file_notify_information structure)

struct __attribute__((__packed__)) smb3_notify {
       uint32_t completion_filter;
       bool     watch_tree;
       uint32_t data_len;
       uint8_t  data[];
} __packed;

using CIFS_IOC_NOTIFY_INFO 0xc009cf0b
 or equivalently _IOWR(CIFS_IOCTL_MAGIC, 11, struct smb3_notify_info)

The ioctl will block until the server detects a change to that
directory or its subdirectories (if watch_tree is set).

5e91e57e68 perf auxtrace arm64: Add support for parsing HiSilicon PCIe Trace packet
Add support for using 'perf report --dump-raw-trace' to parse PTT packet.

Example usage:

Output will contain raw PTT data and its textual representation, such
as (8DW format):

This patch only add basic parsing support according to the definition of
the PTT packet described in Documentation/trace/hisi-ptt.rst. And the
fields of each packet can be further decoded following the PCIe Spec's
definition of TLP packet.

58d4802a5e perf tests stat+json_output: Include sanity check for topology
Testcase stat+json_output.sh fails in powerpc:

	86: perf stat JSON output linter : FAILED!

The testcase "stat+json_output.sh" verifies perf stat JSON output. The
test covers aggregation modes like per-socket, per-core, per-die, -A
(no_aggr mode) along with few other tests. It counts expected fields for
various commands. For example say -A (i.e, AGGR_NONE mode), expects 7
fields in the output having "CPU" as first field. Same way, for
per-socket, it expects the first field in result to point to socket id.
The testcases compares the result with expected count.

The values for socket, die, core and cpu are fetched from topology
directory:

  /sys/devices/system/cpu/cpu*/topology.

For example, socket value is fetched from "physical_package_id" file of
topology directory.  (cpu__get_topology_int() in util/cpumap.c)

If a platform fails to fetch the topology information, values will be
set to -1. For example, incase of pSeries platform of powerpc, value for
"physical_package_id" is restricted and not exposed. So, -1 will be
assigned.

Perf code has a checks for valid cpu id in "aggr_printout"
(stat-display.c), which displays the fields. So, in cases where topology
values not exposed, first field of the output displaying will be empty.
This cause the testcase to fail, as it counts  number of fields in the
output.

Incase of -A (AGGR_NONE mode,), testcase expects 7 fields in the output,
becos of -1 value obtained from topology files for some, only 6 fields
are printed. Hence a testcase failure reported due to mismatch in number
of fields in the output.

Patch here adds a sanity check in the testcase for topology.  Check will
help to skip the test if -1 value found.

Add tests:

	Test with/without CYC
	Test recording with sample mode
	Test with kernel trace
	Test virtual LBR
	Test power events
	Test with TNT packets disabled
	Test with event_trace

These tests mostly check that perf record works with the corresponding
Intel PT config terms, sometimes also checking that certain packets do or
do not appear in the resulting trace as appropriate.

The "Test virtual LBR" is slightly trickier, using a Python script to
check that branch stacks are actually synthesized.

c461c677a8 clk: tegra: Fix Tegra PWM parent clock
Commit 8c193f4714 ("pwm: tegra: Optimize period calculation") updated
the period calculation in the Tegra PWM driver and now returns an error
if the period requested is less than minimum period supported. This is
breaking PWM support on various Tegra platforms. For example, on the
Tegra210 Jetson Nano platform this is breaking the PWM fan support and
probing the PWM fan driver now fails ...

 pwm-fan pwm-fan: Failed to configure PWM: -22
 pwm-fan: probe of pwm-fan failed with error -22

The problem is that the default parent clock for the PWM on Tegra210 is
a 32kHz clock and is unable to support the requested PWM period.

Fix PWM support on Tegra20, Tegra30, Tegra114, Tegra124 and Tegra210 by
updating the parent clock for the PWM to be the PLL_P.

Fixes: 8c193f4714 ("pwm: tegra: Optimize period calculation")
