602684adb4 docs: Update version number from 5.x to 6.x in README.rst
A quick 'grep "5\.x" . -R' on Documentation shows that README.rst,
2.Process.rst and applying-patches.rst all mention the version number "5.x"
for kernel releases.

As the next release will be version 6.0, updating the version number to 6.x
in README.rst seems reasonable.

The description in 2.Process.rst is just a description of recent kernel
releases, it was last updated in the beginning of 2020, and can be
revisited at any time on a regular basis, independent of changing the
version number from 5 to 6. So, there is no need to update this document
now when transitioning from 5.x to 6.x numbering.

The document applying-patches.rst is probably obsolete for most users
anyway, a reader will sufficiently well understand the steps, even it
mentions version 5 rather than version 6. So, do not update that to a
version 6.x numbering scheme.

Update version number from 5.x to 6.x in README.rst only.

e89d120c4b arm64: errata: add detection for AMEVCNTR01 incrementing incorrectly
The AMU counter AMEVCNTR01 (constant counter) should increment at the same
rate as the system counter. On affected Cortex-A510 cores, AMEVCNTR01
increments incorrectly giving a significantly higher output value. This
results in inaccurate task scheduler utilization tracking and incorrect
feedback on CPU frequency.

Work around this problem by returning 0 when reading the affected counter
in key locations that results in disabling all users of this counter from
using it either for frequency invariance or as FFH reference counter. This
effect is the same to firmware disabling affected counters.

Details on how the two features are affected by this erratum:

 - AMU counters will not be used for frequency invariance for affected
   CPUs and CPUs in the same cpufreq policy. AMUs can still be used for
   frequency invariance for unaffected CPUs in the system. Although
   unlikely, if no alternative method can be found to support frequency
   invariance for affected CPUs (cpufreq based or solution based on
   platform counters) frequency invariance will be disabled. Please check
   the chapter on frequency invariance at
   Documentation/scheduler/sched-capacity.rst for details of its effect.

 - Given that FFH can be used to fetch either the core or constant counter
   values, restrictions are lifted regarding any of these counters
   returning a valid (!0) value. Therefore FFH is considered supported
   if there is a least one CPU that support AMUs, independent of any
   counters being disabled or affected by this erratum. Clarifying
   comments are now added to the cpc_ffh_supported(), cpu_read_constcnt()
   and cpu_read_corecnt() functions.

The above is achieved through adding a new erratum: ARM64_ERRATUM_2457168.

2e8cff0a0e arm64: fix rodata=full
On arm64, "rodata=full" has been suppored (but not documented) since
commit:

  c55191e96c ("arm64: mm: apply r/o permissions of VM areas to its linear alias as well")

As it's necessary to determine the rodata configuration early during
boot, arm64 has an early_param() handler for this, whereas init/main.c
has a __setup() handler which is run later.

Unfortunately, this split meant that since commit:

  f9a40b0890 ("init/main.c: return 1 from handled __setup() functions")

... passing "rodata=full" would result in a spurious warning from the
__setup() handler (though RO permissions would be configured
appropriately).

Further, "rodata=full" has been broken since commit:

  0d6ea3ac94 ("lib/kstrtox.c: add "false"/"true" support to kstrtobool()")

... which caused strtobool() to parse "full" as false (in addition to
many other values not documented for the "rodata=" kernel parameter.

This patch fixes this breakage by:

* Moving the core parameter parser to an __early_param(), such that it
  is available early.

* Adding an (optional) arch hook which arm64 can use to parse "full".

* Updating the documentation to mention that "full" is valid for arm64.

* Having the core parameter parser handle "on" and "off" explicitly,
  such that any undocumented values (e.g. typos such as "ful") are
  reported as errors rather than being silently accepted.

Note that __setup() and early_param() have opposite conventions for
their return values, where __setup() uses 1 to indicate a parameter was
handled and early_param() uses 0 to indicate a parameter was handled.

Fixes: f9a40b0890 ("init/main.c: return 1 from handled __setup() functions")
Fixes: 0d6ea3ac94 ("lib/kstrtox.c: add "false"/"true" support to kstrtobool()")

Correct the schema to express such case and fix warnings like:

  qcom/msm8916-alcatel-idol347.dtb: gyroscope@68: interrupts: [[97, 1], [98, 1]] is too long

a0a12c3ed0 asm goto: eradicate CC_HAS_ASM_GOTO
GCC has supported asm goto since 4.5, and Clang has since version 9.0.0.
The minimum supported versions of these tools for the build according to
Documentation/process/changes.rst are 5.1 and 11.0.0 respectively.

Remove the feature detection script, Kconfig option, and clean up some
fallback code that is no longer supported.

The removed script was also testing for a GCC specific bug that was
fixed in the 4.7 release.

Also remove workarounds for bpftrace using clang older than 9.0.0, since
other BPF backend fixes are required at this point.

cee7db1b02 docs: kerneldoc-preamble: Test xeCJK.sty before loading
On distros whose texlive packaging is fine-grained, texlive-xecjk
can be installed/removed independently of other texlive packages.
Conditionally loading xeCJK depending only on the existence of the
"Noto Sans CJK SC" font might end up in xelatex error of
"xeCJK.sty not found!".

Improve the situation by testing existence of xeCJK.sty before
loading it.

This is useful on RHEL 9 and its clone distros where texlive-xecjk
doesn't work at the moment due to a missing dependency [1].
"make pdfdocs" for non-CJK contents should work after removing
texlive-xecjk.

415d832497 locking/atomic: Make test_and_*_bit() ordered on failure
These operations are documented as always ordered in
include/asm-generic/bitops/instrumented-atomic.h, and producer-consumer
type use cases where one side needs to ensure a flag is left pending
after some shared data was updated rely on this ordering, even in the
failure case.

This is the case with the workqueue code, which currently suffers from a
reproducible ordering violation on Apple M1 platforms (which are
notoriously out-of-order) that ends up causing the TTY layer to fail to
deliver data to userspace properly under the right conditions.  This
change fixes that bug.

Change the documentation to restrict the "no order on failure" story to
the _lock() variant (for which it makes sense), and remove the
early-exit from the generic implementation, which is what causes the
missing barrier semantics in that case.  Without this, the remaining
atomic op is fully ordered (including on ARM64 LSE, as of recent
versions of the architecture spec).

8c59632423 dt-bindings: thermal: Fix missing required property
When the thermal zone description was converted to yaml schema, the
required 'trips' property was forgotten.

The initial text bindings was describing:

"
[ ... ]

* Thermal zone nodes

The thermal zone node is the node containing all the required info
for describing a thermal zone, including its cooling device bindings. The
thermal zone node must contain, apart from its own properties, one sub-node
containing trip nodes and one sub-node containing all the zone cooling maps.

Required properties:
- polling-delay:        The maximum number of milliseconds to wait between polls
  Type: unsigned        when checking this thermal zone.
  Size: one cell

- polling-delay-passive: The maximum number of milliseconds to wait
  Type: unsigned        between polls when performing passive cooling.
  Size: one cell

- thermal-sensors:      A list of thermal sensor phandles and sensor specifier
  Type: list of         used while monitoring the thermal zone.
  phandles + sensor
  specifier

- trips:                A sub-node which is a container of only trip point nodes
  Type: sub-node        required to describe the thermal zone.

Optional property:
- cooling-maps:         A sub-node which is a container of only cooling device
  Type: sub-node        map nodes, used to describe the relation between trips
                        and cooling devices.
  [ ... ]

"

Now the schema describes:

"
    [ ... ]

    required:
      - polling-delay
      - polling-delay-passive
      - thermal-sensors

    [ ... ]
"

Add the missing 'trips' property in the required properties.

402c43ea6b xen-blkfront: Apply 'feature_persistent' parameter when connect
In some use cases[1], the backend is created while the frontend doesn't
support the persistent grants feature, but later the frontend can be
changed to support the feature and reconnect.  In the past, 'blkback'
enabled the persistent grants feature since it unconditionally checked
if frontend supports the persistent grants feature for every connect
('connect_ring()') and decided whether it should use persistent grans or
not.

However, commit aac8a70db2 ("xen-blkback: add a parameter for
disabling of persistent grants") has mistakenly changed the behavior.
It made the frontend feature support check to not be repeated once it
shown the 'feature_persistent' as 'false', or the frontend doesn't
support persistent grants.

Similar behavioral change has made on 'blkfront' by commit 74a852479c
("xen-blkfront: add a parameter for disabling of persistent grants").
This commit changes the behavior of the parameter to make effect for
every connect, so that the previous behavior of 'blkfront' can be
restored.
