68d247ad38 parisc: Default to 16 CPUs on 32-bit kernel 
Qemu currently supports up to 16 CPUs, so increase the default from 4 to 16.
Bload-o-meter shows only an increase of 800 bytes with this change.

16f035d9e2 sections: Fix __is_kernel() to include init ranges 
With CONFIG_KALLSYMS_ALL=y, the function is_ksym_addr() is used to
determine if a symbol is from inside the kernel range. For that the
given symbol address is checked if it's inside the _stext to _end range.

Although this is correct, some architectures (e.g. parisc) may have the
init area before the _stext address and as such the check in
is_ksym_addr() fails.  By extending the range check to include the init
section, __is_kernel() will now detect symbols in this range as well.

This fixes an issue on parisc where addresses of kernel functions in
init sections aren't resolved to their symbol names.

e486288d11 parisc: Re-use toc_stack as hpmc_stack 
No need to have an own hpmc_stack. Just re-use the toc_stack of the
monarch CPU as either a TOC or a HPMC will happen at the same time.
This reduces the kernel memory footprint by 16k.

d6ab9fc745 parisc: Enable TOC (transfer of contents) feature unconditionally 
Before this patch, the TOC code used a pre-allocated stack of 16kb for
each possible CPU. That space overhead was the reason why the TOC
feature wasn't enabled by default for 32-bit kernels.

This patch rewrites the TOC code to use a per-cpu stack. That way we use
much less memory now and as such we enable the TOC feature by default on
all kernels.

Additionally the dump of the registers and the stacktrace wasn't
serialized, which led to multiple CPUs printing the stack backtrace at
once which rendered the output unreadable.
Now the backtraces are nicely serialized by a lock.

aa8589aac8 PCI: brcmstb: Augment driver for MIPs SOCs 
The current brcmstb driver works for Arm and Arm64.  A few things are
modified here for us to support MIPs as well.

  o There are four outbound range register groups and each directs a window
    of up to 128MB.  Even though there are four 128MB DT "ranges" in the
    bmips PCIe DT node, these ranges are contiguous and are collapsed into
    a single range by the OF range parser.  Now the driver assumes a single
    range -- for MIPs only -- and splits it back into 128MB sizes.

  o For bcm7425, the config space accesses must be 32-bit reads or
    writes.  In addition, the 4k config space register array is missing
    and not used.

  o The registers for the upper 32-bits of the outbound window address do
    not exist.

  o Burst size must be set to 256 (this refers to an internal bus).

d552ddeaab MIPS: bmips: Remove obsolete DMA mapping support 
The code in 'arch/mips/bmips/dma.c' performed DMA mapping for inbound
regions.  This mapping was and is required for the Broadcom STB PCIe
controller HW.  This code is removed as the current 'struct device' has a
@dma_range_map field which performs the same functionality by processing
the "dma-ranges" DT property.

Subsequently, ARCH_HAS_PHYS_TO_DMA is now unset since the dma_to_phys()
and phys_to_dma() functions are removed.

1e9d74660d bpf: Fix mount source show for bpffs 
We noticed our tc ebpf tools can't start after we upgrade our in-house kernel
version from 4.19 to 5.10. That is because of the behaviour change in bpffs
caused by commit d2935de7e4 ("vfs: Convert bpf to use the new mount API").

In our tc ebpf tools, we do strict environment check. If the environment is
not matched, we won't allow to start the ebpf progs. One of the check is whether
bpffs is properly mounted. The mount information of bpffs in kernel-4.19 and
kernel-5.10 are as follows:

- kernel 4.19
$ mount -t bpf bpffs /sys/fs/bpf
$ mount -t bpf
bpffs on /sys/fs/bpf type bpf (rw,relatime)

- kernel 5.10
$ mount -t bpf bpffs /sys/fs/bpf
$ mount -t bpf
none on /sys/fs/bpf type bpf (rw,relatime)

The device name in kernel-5.10 is displayed as none instead of bpffs, then our
environment check fails. Currently we modify the tools to adopt to the kernel
behaviour change, but I think we'd better change the kernel code to keep the
behavior consistent.

After this change, the mount information will be displayed the same with the
behavior in kernel-4.19, for example:

$ mount -t bpf bpffs /sys/fs/bpf
$ mount -t bpf
bpffs on /sys/fs/bpf type bpf (rw,relatime)

19d1c32652 9p: fix enodata when reading growing file 
Reading from a file that was just extended by a write, but the write had
not yet reached the server would return ENODATA as illustrated by this
command:
$ xfs_io -c 'open -ft test' -c 'w 4096 1000' -c 'r 0 1000'
wrote 1000/1000 bytes at offset 4096
1000.000000 bytes, 1 ops; 0.0001 sec (5.610 MiB/sec and 5882.3529 ops/sec)

Fix this case by having netfs assume zeroes when reads from server come

Pull power management updates from Rafael Wysocki:
 "The most signigicant change here is the addition of a new cpufreq
  'P-state' driver for AMD processors as a better replacement for the
  venerable acpi-cpufreq driver.

  There are also other cpufreq updates (in the core, intel_pstate, ARM
  drivers), PM core updates (mostly related to adding new macros for
  declaring PM operations which should make the lives of driver
  developers somewhat easier), and a bunch of assorted fixes and
  cleanups.

  Summary:

   - Add new P-state driver for AMD processors (Huang Rui).

   - Fix initialization of min and max frequency QoS requests in the
     cpufreq core (Rafael Wysocki).

   - Fix EPP handling on Alder Lake in intel_pstate (Srinivas
     Pandruvada).

   - Make intel_pstate update cpuinfo.max_freq when notified of HWP
     capabilities changes and drop a redundant function call from that
     driver (Rafael Wysocki).

   - Improve IRQ support in the Qcom cpufreq driver (Ard Biesheuvel,
     Stephen Boyd, Vladimir Zapolskiy).

   - Fix double devm_remap() in the Mediatek cpufreq driver (Hector
     Yuan).

   - Introduce thermal pressure helpers for cpufreq CPU cooling (Lukasz
     Luba).

   - Make cpufreq use default_groups in kobj_type (Greg Kroah-Hartman).

   - Make cpuidle use default_groups in kobj_type (Greg Kroah-Hartman).

   - Fix two comments in cpuidle code (Jason Wang, Yang Li).

   - Allow model-specific normal EPB value to be used in the intel_epb
     sysfs attribute handling code (Srinivas Pandruvada).

   - Simplify locking in pm_runtime_put_suppliers() (Rafael Wysocki).

   - Add safety net to supplier device release in the runtime PM core
     code (Rafael Wysocki).

   - Capture device status before disabling runtime PM for it (Rafael
     Wysocki).

   - Add new macros for declaring PM operations to allow drivers to
     avoid guarding them with CONFIG_PM #ifdefs or __maybe_unused and
     update some drivers to use these macros (Paul Cercueil).

   - Allow ACPI hardware signature to be honoured during restore from
     hibernation (David Woodhouse).

   - Update outdated operating performance points (OPP) documentation
     (Tang Yizhou).

   - Reduce log severity for informative message regarding frequency
     transition failures in devfreq (Tzung-Bi Shih).

   - Add DRAM frequency controller devfreq driver for Allwinner sunXi
     SoCs (Samuel Holland).

   - Add missing COMMON_CLK dependency to sun8i devfreq driver (Arnd
     Bergmann).

   - Add support for new layout of Psys PowerLimit Register on SPR to
     the Intel RAPL power capping driver (Zhang Rui).

   - Fix typo in a comment in idle_inject.c (Jason Wang).

   - Remove unused function definition from the DTPM (Dynamit Thermal
     Power Management) power capping framework (Daniel Lezcano).

   - Reduce DTPM trace verbosity (Daniel Lezcano)"

63045bfd3c netfilter: nf_tables: don't use 'data_size' uninitialized 
Commit 2c865a8a28 ("netfilter: nf_tables: add rule blob layout") never
initialized the new 'data_size' variable.

I'm not sure how it ever worked, but it might have worked almost by
accident - gcc seems to occasionally miss these kinds of 'variable used
uninitialized' situations, but I've seen it do so because it ended up
zero-initializing them due to some other simplification.

But clang is very unhappy about it all, and correctly reports

    net/netfilter/nf_tables_api.c:8278:4: error: variable 'data_size' is uninitialized when used here [-Werror,-Wuninitialized]
                            data_size += sizeof(*prule) + rule->dlen;
                            ^~~~~~~~~
    net/netfilter/nf_tables_api.c:8263:30: note: initialize the variable 'data_size' to silence this warning
            unsigned int size, data_size;
                                        ^
                                         = 0
    1 error generated.

and this fix just initializes 'data_size' to zero before the loop.

8efd0d9c31 Networking changes for 5.17. 
Core
 ----
 
  - Defer freeing TCP skbs to the BH handler, whenever possible,
    or at least perform the freeing outside of the socket lock section
    to decrease cross-CPU allocator work and improve latency.
 
  - Add netdevice refcount tracking to locate sources of netdevice
    and net namespace refcount leaks.
 
  - Make Tx watchdog less intrusive - avoid pausing Tx and restarting
    all queues from a single CPU removing latency spikes.
 
  - Various small optimizations throughout the stack from Eric Dumazet.
 
  - Make netdev->dev_addr[] constant, force modifications to go via
    appropriate helpers to allow us to keep addresses in ordered data
    structures.
 
  - Replace unix_table_lock with per-hash locks, improving performance
    of bind() calls.
 
  - Extend skb drop tracepoint with a drop reason.
 
  - Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.
 
 BPF
 ---
 
  - New helpers:
    - bpf_find_vma(), find and inspect VMAs for profiling use cases
    - bpf_loop(), runtime-bounded loop helper trading some execution
      time for much faster (if at all converging) verification
    - bpf_strncmp(), improve performance, avoid compiler flakiness
    - bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt()
      for tracing programs, all inlined by the verifier
 
  - Support BPF relocations (CO-RE) in the kernel loader.
 
  - Further the support for BTF_TYPE_TAG annotations.
 
  - Allow access to local storage in sleepable helpers.
 
  - Convert verifier argument types to a composable form with different
    attributes which can be shared across types (ro, maybe-null).
 
  - Prepare libbpf for upcoming v1.0 release by cleaning up APIs,
    creating new, extensible ones where missing and deprecating those
    to be removed.
 
 Protocols
 ---------
 
  - WiFi (mac80211/cfg80211):
    - notify user space about long "come back in N" AP responses,
      allow it to react to such temporary rejections
    - allow non-standard VHT MCS 10/11 rates
    - use coarse time in airtime fairness code to save CPU cycles
 
  - Bluetooth:
    - rework of HCI command execution serialization to use a common
      queue and work struct, and improve handling errors reported
      in the middle of a batch of commands
    - rework HCI event handling to use skb_pull_data, avoiding packet
      parsing pitfalls
    - support AOSP Bluetooth Quality Report
 
  - SMC:
    - support net namespaces, following the RDMA model
    - improve connection establishment latency by pre-clearing buffers
    - introduce TCP ULP for automatic redirection to SMC
 
  - Multi-Path TCP:
    - support ioctls: SIOCINQ, OUTQ, and OUTQNSD

      IPV6_FREEBIND, and IPV6_TRANSPARENT, TCP_CORK and TCP_NODELAY
    - support cmsgs: TCP_INQ
    - improvements in the data scheduler (assigning data to subflows)
    - support fastclose option (quick shutdown of the full MPTCP
      connection, similar to TCP RST in regular TCP)
 
  - MCTP (Management Component Transport) over serial, as defined by
    DMTF spec DSP0253 - "MCTP Serial Transport Binding".
 
 Driver API
 ----------
 
  - Support timestamping on bond interfaces in active/passive mode.
 
  - Introduce generic phylink link mode validation for drivers which
    don't have any quirks and where MAC capability bits fully express
    what's supported. Allow PCS layer to participate in the validation.
    Convert a number of drivers.
 
  - Add support to set/get size of buffers on the Rx rings and size of
    the tx copybreak buffer via ethtool.
 
  - Support offloading TC actions as first-class citizens rather than
    only as attributes of filters, improve sharing and device resource
    utilization.
 
  - WiFi (mac80211/cfg80211):
    - support forwarding offload (ndo_fill_forward_path)
    - support for background radar detection hardware
    - SA Query Procedures offload on the AP side

Pull networking updates from Jakub Kicinski:
 "Core
  ----

   - Defer freeing TCP skbs to the BH handler, whenever possible, or at
     least perform the freeing outside of the socket lock section to
     decrease cross-CPU allocator work and improve latency.

   - Add netdevice refcount tracking to locate sources of netdevice and
     net namespace refcount leaks.

   - Make Tx watchdog less intrusive - avoid pausing Tx and restarting
     all queues from a single CPU removing latency spikes.

   - Various small optimizations throughout the stack from Eric Dumazet.

   - Make netdev->dev_addr[] constant, force modifications to go via
     appropriate helpers to allow us to keep addresses in ordered data
     structures.

   - Replace unix_table_lock with per-hash locks, improving performance
     of bind() calls.

   - Extend skb drop tracepoint with a drop reason.

   - Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.

  BPF
  ---

   - New helpers:
      - bpf_find_vma(), find and inspect VMAs for profiling use cases
      - bpf_loop(), runtime-bounded loop helper trading some execution
        time for much faster (if at all converging) verification
      - bpf_strncmp(), improve performance, avoid compiler flakiness
      - bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt()
        for tracing programs, all inlined by the verifier

   - Support BPF relocations (CO-RE) in the kernel loader.

   - Further the support for BTF_TYPE_TAG annotations.

   - Allow access to local storage in sleepable helpers.

   - Convert verifier argument types to a composable form with different
     attributes which can be shared across types (ro, maybe-null).

   - Prepare libbpf for upcoming v1.0 release by cleaning up APIs,
     creating new, extensible ones where missing and deprecating those
     to be removed.

  Protocols
  ---------

   - WiFi (mac80211/cfg80211):
      - notify user space about long "come back in N" AP responses,
        allow it to react to such temporary rejections
      - allow non-standard VHT MCS 10/11 rates
      - use coarse time in airtime fairness code to save CPU cycles

   - Bluetooth:
      - rework of HCI command execution serialization to use a common
        queue and work struct, and improve handling errors reported in
        the middle of a batch of commands
      - rework HCI event handling to use skb_pull_data, avoiding packet
        parsing pitfalls
      - support AOSP Bluetooth Quality Report

   - SMC:
      - support net namespaces, following the RDMA model
      - improve connection establishment latency by pre-clearing buffers
      - introduce TCP ULP for automatic redirection to SMC

   - Multi-Path TCP:
      - support ioctls: SIOCINQ, OUTQ, and OUTQNSD
      - support socket options: IP_TOS, IP_FREEBIND, IP_TRANSPARENT,
        IPV6_FREEBIND, and IPV6_TRANSPARENT, TCP_CORK and TCP_NODELAY
      - support cmsgs: TCP_INQ
      - improvements in the data scheduler (assigning data to subflows)
      - support fastclose option (quick shutdown of the full MPTCP
        connection, similar to TCP RST in regular TCP)

   - MCTP (Management Component Transport) over serial, as defined by
     DMTF spec DSP0253 - "MCTP Serial Transport Binding".

  Driver API
  ----------

   - Support timestamping on bond interfaces in active/passive mode.

   - Introduce generic phylink link mode validation for drivers which
     don't have any quirks and where MAC capability bits fully express
     what's supported. Allow PCS layer to participate in the validation.
     Convert a number of drivers.

   - Add support to set/get size of buffers on the Rx rings and size of
     the tx copybreak buffer via ethtool.

   - Support offloading TC actions as first-class citizens rather than
     only as attributes of filters, improve sharing and device resource
     utilization.

   - WiFi (mac80211/cfg80211):
      - support forwarding offload (ndo_fill_forward_path)
      - support for background radar detection hardware

75b950ef61 Revert "drm/amd/display: Fix for otg synchronization logic" 
This reverts commit a896f870f8.

It causes odd flickering on my Radeon RX580 (PCI ID 1002:67df rev e7,
subsystem ID 1da2:e353).

Bisected right to this commit, and reverting it fixes things.

Pull slab updates from Vlastimil Babka:

 - Separate struct slab from struct page - an offshot of the page folio
   work.

   Struct page fields used by slab allocators are moved from struct page
   to a new struct slab, that uses the same physical storage. Similar to
   struct folio, it always is a head page. This brings better type
   safety, separation of large kmalloc allocations from true slabs, and
   cleanup of related objcg code.

 - A SLAB_MERGE_DEFAULT config optimization.

Pull random number generator updates from Jason Donenfeld:
 "These a bit more numerous than usual for the RNG, due to folks
  resubmitting patches that had been pending prior and generally renewed
  interest.

  There are a few categories of patches in here:

   1) Dominik Brodowski and I traded a series back and forth for a some
      weeks that fixed numerous issues related to seeds being provided
      at extremely early boot by the firmware, before other parts of the
      kernel or of the RNG have been initialized, both fixing some
      crashes and addressing correctness around early boot randomness.
      One of these is marked for stable.

   2) I replaced the RNG's usage of SHA-1 with BLAKE2s in the entropy
      extractor, and made the construction a bit safer and more
      standard. This was sort of a long overdue low hanging fruit, as we
      were supposed to have phased out SHA-1 usage quite some time ago
      (even if all we needed here was non-invertibility). Along the way
      it also made extraction 131% faster. This required a bit of
      Kconfig and symbol plumbing to make things work well with the
      crypto libraries, which is one of the reasons why I'm sending you
      this pull early in the cycle.

   3) I got rid of a truly superfluous call to RDRAND in the hot path,
      which resulted in a whopping 370% increase in performance.

   4) Sebastian Andrzej Siewior sent some patches regarding PREEMPT_RT,
      the full series of which wasn't ready yet, but the first two
      preparatory cleanups were good on their own. One of them touches
      files in kernel/irq/, which is the other reason why I'm sending
      you this pull early in the cycle.

   5) Other assorted correctness fixes from Eric Biggers, Jann Horn,
      Mark Brown, Dominik Brodowski, and myself"

d5962fb7d6 perf annotate: Avoid TUI crash when navigating in the annotation of recursive functions 
In 'perf report', entering a recursive function from inside of itself
(either directly of indirectly through some other function) results in
calling symbol__annotate2 multiple() times, and freeing the whole
disassembly when exiting from the innermost instance.

The first issue causes the function's disassembly to be duplicated, and
the latter a heap use-after-free (and crash) when trying to access the
disassembly again.

I reproduced the bug on perf 5.11.22 (Ubuntu 20.04.3 LTS) and 5.16.rc8
with the following testcase (compile with gcc recursive.c -o recursive).
To reproduce:

- perf record ./recursive
- perf report
- enter fibonacci and annotate it
- move the cursor on one of the "callq fibonacci" instructions and press enter
  - at this point there will be two copies of the function in the disassembly
- go back by pressing q, and perf will crash

  #include <stdio.h>

  int fibonacci(int n)
  {
      if(n <= 2) return 1;
      return fibonacci(n-1) + fibonacci(n-2);
  }

  int main()
  {
      printf("%d\n", fibonacci(40));
  }

This patch addresses the issue by annotating a function and freeing the
associated memory on exit only if no annotation is already present, so
that a recursive function is only annotated on entry.

e3304c2135 perf sort: Include global and local variants for p_stage_cyc sort key 
Sort key 'p_stage_cyc' is used to present the latency cycles spent in
pipeline stages.

perf has local 'p_stage_cyc' sort key to display this info. There is no
global variant available for this sort key. The local variant shows
latency in a single sample, whereas the global value will be useful to
present the total latency (sum of latencies) in the hist entry. It
represents the latency number multiplied by the number of samples.

Add global ('p_stage_cyc') and local variant ('local_p_stage_cyc') for
this sort key. Use 'local_p_stage_cyc' as default option for "mem" sort
mode.

Also add this to the list of dynamic sort keys and made the
"dynamic_headers" and "arch_specific_sort_keys" as static.
