set from Mauro toward the completion of the RST conversion. I *really*
hope we are getting close to the end of this. Meanwhile, those patches
reach pretty far afield to update document references around the tree;
there should be no actual code changes there. There will be, alas, more of
the usual trivial merge conflicts.
Beyond that we have more translations, improvements to the sphinx
scripting, a number of additions to the sysctl documentation, and lots of
fixes.

Pull arm64 updates from Will Deacon:
"A sizeable pile of arm64 updates for 5.8.
Summary below, but the big two features are support for Branch Target
Identification and Clang's Shadow Call stack. The latter is currently
arm64-only, but the high-level parts are all in core code so it could
easily be adopted by other architectures pending toolchain support
Branch Target Identification (BTI):
- Support for ARMv8.5-BTI in both user- and kernel-space. This allows
branch targets to limit the types of branch from which they can be

- Extend the x86 family/model macros with a steppings dimension,
because x86 life isn't complex enough and Intel uses steppings to
differentiate between different CPUs. :-/
- Convert the TSC deadline timer quirks to the steppings macros.
- Clean up asm mnemonics.
- Fix the handling of an AMD erratum, or in other words, fix a kernel
erratum"

- Add AMD Fam17h RAPL support

Tooling changes:
perf record:
- Introduce --switch-output-event to use arbitrary events to be setup
and read from a side band thread and, when they take place a signal
be sent to the main 'perf record' thread, reusing the --switch-output
code to take perf.data snapshots from the --overwrite ring buffer, e.g.:
# perf record --overwrite -e sched:* \
--switch-output-event syscalls:*connect* \
workload
will take perf.data.YYYYMMDDHHMMSS snapshots up to around the
connect syscalls.
- Add --num-synthesize-threads option to control degree of parallelism of the
synthesize_mmap() code which is scanning /proc/PID/task/PID/maps and can be
time consuming. This mimics pre-existing behaviour in 'perf top'.
perf bench:
- Add a multi-threaded synthesize benchmark.
- Add kallsyms parsing benchmark.
Intel PT support:
- Stitch LBR records from multiple samples to get deeper backtraces,
there are caveats, see the csets for details.
- Allow using Intel PT to synthesize callchains for regular events.
- Add support for synthesizing branch stacks for regular events (cycles,
instructions, etc) from Intel PT data.
Misc changes:
- Updated perf vendor events for power9 and Coresight.
- Add flamegraph.py script via 'perf flamegraph'

of local_lock_t - this primitive comes from the -rt project and identifies
CPU-local locking dependencies normally handled opaquely beind preempt_disable()
or local_irq_save/disable() critical sections.
The generated code on mainline kernels doesn't change as a result, but still there
are benefits: improved debugging and better documentation of data structure
accesses.
The new local_lock_t primitives are introduced and then utilized in a couple of
kernel subsystems. No change in functionality is intended.
There's also other smaller changes and cleanups.

Pull locking updates from Ingo Molnar:
"The biggest change to core locking facilities in this cycle is the
introduction of local_lock_t - this primitive comes from the -rt
project and identifies CPU-local locking dependencies normally handled
opaquely beind preempt_disable() or local_irq_save/disable() critical
sections.
The generated code on mainline kernels doesn't change as a result, but
still there are benefits: improved debugging and better documentation
of data structure accesses.
The new local_lock_t primitives are introduced and then utilized in a
couple of kernel subsystems. No change in functionality is intended.
There's also other smaller changes and cleanups"

"Fixes and new features for pstore.
This is a pretty big set of changes (relative to past pstore pulls),
but it has been in -next for a while. The biggest change here is the
ability to support a block device as a pstore backend, which has been
desired for a while. A lot of additional fixes and refactorings are
also included, mostly in support of the new features.
- refactor pstore locking for safer module unloading (Kees Cook)
- remove orphaned records from pstorefs when backend unloaded (Kees
Cook)
- refactor dump_oops parameter into max_reason (Pavel Tatashin)
- introduce pstore/zone for common code for contiguous storage
(WeiXiong Liao)
- introduce pstore/blk for block device backend (WeiXiong Liao)
- introduce mtd backend (WeiXiong Liao)"

The big change in this release is that Matti Vaittinen has factored out
the linear ranges support into a separate library in lib/ since it is
also useful for at least the power subsystem (and most likely others
too), it helps subsystems which need to map register values into more
useful real world values do so with minimal per-driver code.
- Factoring out of the linear ranges support into a library in lib/
from Matti Vaittinen.
- Trace points for bypass mode.
- Use the consumer name in debugfs to make it easier to understand.
- New drivers for Maxim MAX77826 and MAX8998.

This has been a very active release for the DesignWare driver in
particular - after a long period of inactivity we have had a lot of
people actively working on it for unrelated reasons this cycle with some
of that work still not landed. Otherwise it's been fairly quiet for the
subsystem. Highlights include:
- Lots of performance improvements and fixes for the DesignWare driver
from Serge Semin, Andy Shevchenko, Wan Ahmad Zainie, Clement Leger,
Dinh Nguyen and Jarkko Nikula.
- Support for octal mode transfers in spidev.
- Slave mode support for the Rockchip drivers.
- Support for AMD controllers, Broadcom mspi and Raspberry Pi 4,
and Intel Elkhart Lake.

This has been a very active release for the regmap API for some reason,
a lot of it due to new devices with odd requirements that can sensibly
be handled here.
- Add support for buses implementing a custom reg_update_bits()
method in case the bus has a native operation for this.
- Support 16 bit register addresses in SMBus.
- Allow customization of the device attached to regmap-irq.
- Helpers for bitfield operations and per-port field initializations.

When reading the Documentation/vm/zswap.rst file I fell over this typo.
The parameter is called accept_threshold_percent not accept_threhsold_percent

On the ASUS laptop UX325JA/UX425JA, most of the media keys are not
working due to the ASUS WMI driver fails to be loaded. The ACPI error
as follows leads to the failure of asus_wmi_evaluate_method.
ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [IIA3] at bit offset/length 96/32 exceeds size of target Buffer (96 bits) (20200326/dsopcode-203)
No Local Variables are initialized for Method [WMNB]
ACPI Error: Aborting method \_SB.ATKD.WMNB due to previous error (AE_AML_BUFFER_LIMIT) (20200326/psparse-531)
The DSDT for the WMNB part shows that 5 DWORD required for local
variables and the 3rd variable IIA3 hit the buffer limit.
Method (WMNB, 3, Serialized)
{ ..
CreateDWordField (Arg2, Zero, IIA0)
CreateDWordField (Arg2, 0x04, IIA1)
CreateDWordField (Arg2, 0x08, IIA2)
CreateDWordField (Arg2, 0x0C, IIA3)
CreateDWordField (Arg2, 0x10, IIA4)
Local0 = (Arg1 & 0xFFFFFFFF)
If ((Local0 == 0x54494E49))
..
}
The limitation is determined by the input acpi_buffer size passed
to the wmi_evaluate_method. Since the struct bios_args is the data
structure used as input buffer by default for all ASUS WMI calls,
the size needs to be expanded to fix the problem.
