dbf8be8218 docs/mm: add VMA locks documentation
Locking around VMAs is complicated and confusing.  While we have a number
of disparate comments scattered around the place, we seem to be reaching a
level of complexity that justifies a serious effort at clearly documenting
how locks are expected to be used when it comes to interacting with
mm_struct and vm_area_struct objects.

This is especially pertinent as regards the efforts to find sensible
abstractions for these fundamental objects in kernel rust code whose
compiler strictly requires some means of expressing these rules (and
through this expression, self-document these requirements as well as
enforce them).

The document limits scope to mmap and VMA locks and those that are
immediately adjacent and relevant to them - so additionally covers page
table locking as this is so very closely tied to VMA operations (and
relies upon us handling these correctly).

The document tries to cover some of the nastier and more confusing edge
cases and concerns especially around lock ordering and page table
teardown.

The document is split between generally useful information for users of mm
interfaces, and separately a section intended for mm kernel developers
providing a discussion around internal implementation details.

lens became incomplete. For example, details of resilient nexthop groups
are obviously omitted.

Now that 16-bit nexthop group weights are a thing, the 8-bit UAPI cannot
convey the >8-bit weight accurately. Instead of inventing workarounds for
an obsolete interface, just document the expectations of inaccuracy.

50a062a762 cpufreq/amd-pstate: Store the boost numerator as highest perf again
commit ad4caad58d ("cpufreq: amd-pstate: Merge
amd_pstate_highest_perf_set() into amd_get_boost_ratio_numerator()")
changed the semantics for highest perf and commit 18d9b52271
("cpufreq/amd-pstate: Use nominal perf for limits when boost is disabled")
worked around those semantic changes.

This however is a confusing result and furthermore makes it awkward to
change frequency limits and boost due to the scaling differences. Restore
the boost numerator to highest perf again.

c2b46ae022 ACPI/IORT: Add PMCG platform information for HiSilicon HIP09A
HiSilicon HIP09A platforms using the same SMMU PMCG with HIP09
and thus suffers the same erratum. List them in the PMCG platform
information list without introducing a new SMMU PMCG Model.

Update the silicon-errata.rst as well.

282615d133 dt-bindings: phy: imx8mq-usb: correct reference to usb-switch.yaml
The i.MX95 usb-phy can work with or without orientation-switch. With
current setting, if usb-phy works without orientation-switch, the
dt-schema check will show below error:

phy@4c1f0040: 'oneOf' conditional failed, one must be fixed:
        'port' is a required property
        'ports' is a required property
        from schema $id: http://devicetree.org/schemas/phy/fsl,imx8mq-usb-phy.yaml#

This will correct the behavior of referring to usb-switch.yaml.

ceb8bf2cea module: Convert default symbol namespace to string literal
Commit cdd30ebb1b ("module: Convert symbol namespace to string
literal") only converted MODULE_IMPORT_NS() and EXPORT_SYMBOL_NS(),
leaving DEFAULT_SYMBOL_NAMESPACE as a macro expansion.

This commit converts DEFAULT_SYMBOL_NAMESPACE in the same way to avoid
annoyance for the default namespace as well.

This reverts the misconversions introduced by commit cdd30ebb1b
("module: Convert symbol namespace to string literal").

The affected descriptions refer to MODULE_IMPORT_NS() tags in general,
rather than suggesting the use of the empty string ("") as the
namespace.

Clean up the existing export namespace code along the same lines of
commit 33def8498f ("treewide: Convert macro and uses of __section(foo)

namespace argument to be a macro expansion itself.

The MT8188 SoC has a more in-depth power-domain tree, and the
CHECK_DTBS=y check could fail because the current MediaTek power
dt-binding is insufficient to cover its CAM_SUBA and CAM_SUBB
sub-domains.

Add one more nested power-domain layer to pass the check.

d8b78066f4 TTY / Serial driver updates for 6.13-rc1
Here is a small set of tty and serial driver updates for 6.13-rc1.
 Nothing major at all this time, only some small changes:
   - few device tree binding updates
   - 8250_exar serial driver updates
   - imx serial driver updates
   - sprd_serial driver updates
   - other tiny serial driver updates, full details in the shortlog
 
 All of these have been in linux-next for a while with one reported
 issue, but that commit has now been reverted.

2eff01ee28 Char/Misc/IIO/Whatever driver subsystem updates for 6.13-rc1
Here is the "big and hairy" char/misc/iio and other small driver
 subsystem updates for 6.13-rc1.  Sorry for doing this at the end of the
 merge window, conference and holiday travel got in the way on my side
 (hence the 5am pull request emails...)
 
 Loads of things in here, and even a fun merge conflict!
   - rust misc driver bindings and other rust changes to make misc
     drivers actually possible.  I think this is the tipping point,
     expect to see way more rust drivers going forward now that these
     bindings are present.  Next merge window hopefully we will have pci
     and platform drivers working, which will fully enable almost all
     driver subsystems to start accepting (or at least getting) rust
     drivers.  This is the end result of a lot of work from a lot of
     people, congrats to all of them for getting this far, you've proved
     many of us wrong in the best way possible, working code :)
   - IIO driver updates, too many to list individually, that subsystem
     keeps growing and growing...
   - Interconnect driver updates
   - nvmem driver updates
   - pwm driver updates
   - platform_driver::remove() fixups, loads of them
   - counter driver updates
   - misc driver updates (keba?)
   - binder driver updates and fixes
   - loads of other small char/misc/etc driver updates and additions,
     full details in the shortlog.
 
 Note, there is a semi-hairy rust merge conflict when pulling this.  The
 resolution has been in linux-next for a while and can be seen here:
 	https://lore.kernel.org/all/20241111173459.2646d4af@canb.auug.org.au/
 
 All of these have been in linux-next for a while, with no other reported
 issues other than that merge conflict.

Here is a small set of driver core changes for 6.13-rc1.
 
 Nothing major for this merge cycle, except for the 2 simple merge
 conflicts are here just to make life interesting.
 
 Included in here are:
   - sysfs core changes and preparations for more sysfs api cleanups that
     can come through all driver trees after -rc1 is out
   - fw_devlink fixes based on many reports and debugging sessions
   - list_for_each_reverse() removal, no one was using it!
   - last-minute seq_printf() format string bug found and fixed in many
     drivers all at once.
   - minor bugfixes and changes full details in the shortlog
 
 As mentioned above, there is 2 merge conflicts with your tree, one is
 where the file is removed (easy enough to resolve), the second is a
 build time error, that has been found in linux-next and the fix can be
 seen here:
 	https://lore.kernel.org/r/20241107212645.41252436@canb.auug.org.au
 
 Other than that, the changes here have been in linux-next with no other
 reported issues.

7af08b57bc Tracing updates for 6.13:
- Add trace flag for NEED_RESCHED_LAZY
 
   Now that NEED_RESCHED_LAZY is upstream, add it to the status bits of the
   common_flags. This will now show when the NEED_RESCHED_LAZY flag is set that
   is used for debugging latency issues in the kernel via a trace.
 
 - Remove leftover "__idx" variable when SRCU was removed from the tracepoint
   code
 
 - Add rcu_tasks_trace guard
 
   To add a guard() around the tracepoint code, a rcu_tasks_trace guard needs
   to be created first.
 
 - Remove __DO_TRACE() macro and just call __DO_TRACE_CALL() directly
 
   The DO_TRACE() macro has conditional locking depending on what was passed
   into the macro parameters. As the guts of the macro has been moved to
   __DO_TRACE_CALL() to handle static call logic, there's no reason to keep
   the __DO_TRACE() macro around. It is better to just do the locking in
   place without the conditionals and call __DO_TRACE_CALL() from those
   locations. The "cond" passed in can also be moved out of that macro.
   This simplifies the code.
 
 - Remove the "cond" from the system call tracepoint macros
 
   The "cond" variable was added to allow some tracepoints to check a
   condition within the static_branch (jump/nop) logic. The system calls do
   not need this. Removing it simplifies the code.
 
 - Replace scoped_guard() with just guard() in the tracepoint logic
 
   guard() works just as well as scoped_guard() in the tracepoint logic and
   the scoped_guard() causes some issues.

8cd07cc6c8 kbuild: allow to start building external modules in any directory
Unless an explicit O= option is provided, external module builds must
start from the kernel directory.

This can be achieved by using the -C option:

  $ make -C /path/to/kernel M=/path/to/external/module

This commit allows starting external module builds from any directory,
so you can also do the following:

  $ make -f /path/to/kernel/Makefile M=/path/to/external/module

The key difference is that the -C option changes the working directory
and parses the Makefile located there, while the -f option only
specifies the Makefile to use.

As shown in the examples in Documentation/kbuild/modules.rst, external
modules usually have a wrapper Makefile that allows you to build them
without specifying any make arguments. The Makefile typically contains
a rule as follows:

    KDIR ?= /path/to/kernel
    default:
            $(MAKE) -C $(KDIR) M=$(CURDIR) $(MAKECMDGOALS)

The log will appear as follows:

    $ make
    make -C /path/to/kernel M=/path/to/external/module
    make[1]: Entering directory '/path/to/kernel'
    make[2]: Entering directory '/path/to/external/module'
      CC [M]  helloworld.o
      MODPOST Module.symvers
      CC [M]  helloworld.mod.o
      CC [M]  .module-common.o
      LD [M]  helloworld.ko
    make[2]: Leaving directory '/path/to/external/module'
    make[1]: Leaving directory '/path/to/kernel'

This changes the working directory twice because the -C option first
switches to the kernel directory, and then Kbuild internally recurses
back to the external module directory.

With this commit, the wrapper Makefile can directly include the kernel
Makefile:

    KDIR ?= /path/to/kernel
    export KBUILD_EXTMOD := $(realpath $(dir $(lastword $(MAKEFILE_LIST))))
    include $(KDIR)/Makefile

This avoids unnecessary sub-make invocations:

    $ make
      CC [M]  helloworld.o
      MODPOST Module.symvers
      CC [M]  helloworld.mod.o
      CC [M]  .module-common.o
      LD [M]  helloworld.ko

11b3d5175e kbuild: support building external modules in a separate build directory
There has been a long-standing request to support building external
modules in a separate build directory.

This commit introduces a new environment variable, KBUILD_EXTMOD_OUTPUT,
and its shorthand Make variable, MO.

A simple usage:

 $ make -C <kernel-dir> M=<module-src-dir> MO=<module-build-dir>

13b25489b6 kbuild: change working directory to external module directory with M=
Currently, Kbuild always operates in the output directory of the kernel,
even when building external modules. This increases the risk of external
module Makefiles attempting to write to the kernel directory.

This commit switches the working directory to the external module
directory, allowing the removal of the $(KBUILD_EXTMOD)/ prefix from
some build artifacts.

The command for building external modules maintains backward
compatibility, but Makefiles that rely on working in the kernel
directory may break. In such cases, $(objtree) and $(srctree) should
be used to refer to the output and source directories of the kernel.

The appearance of the build log will change as follows:

[Before]

  $ make -C /path/to/my/linux M=/path/to/my/externel/module
  make: Entering directory '/path/to/my/linux'
    CC [M]  /path/to/my/externel/module/helloworld.o
    MODPOST /path/to/my/externel/module/Module.symvers
    CC [M]  /path/to/my/externel/module/helloworld.mod.o
    CC [M]  /path/to/my/externel/module/.module-common.o
    LD [M]  /path/to/my/externel/module/helloworld.ko
  make: Leaving directory '/path/to/my/linux'

[After]

  $ make -C /path/to/my/linux M=/path/to/my/externel/module
  make: Entering directory '/path/to/my/linux'
  make[1]: Entering directory '/path/to/my/externel/module'
    CC [M]  helloworld.o
    MODPOST Module.symvers
    CC [M]  helloworld.mod.o
    CC [M]  .module-common.o
    LD [M]  helloworld.ko
  make[1]: Leaving directory '/path/to/my/externel/module'
  make: Leaving directory '/path/to/my/linux'

Printing "Entering directory" twice is cumbersome. This will be
addressed later.
