Subject: [GIT PULL] arm64 updates for 6.10
Message-ID: <20240513152955.GA28901@willie-the-truck>

Hi Linus,

Please pull these arm64 updates for 6.10. There's a summary in the tag,
but the most interesting parts are probably the mm changes from Ryan
which optimise the creation of the linear mapping at boot and
(separately) implement write-protect support for userfaultfd.

Outside of our usual directories, the Kbuild-related changes under
scripts/ have been acked by Masahiro whilst the drivers/acpi/ parts have
been acked by Rafael and the addition of cpumask_any_and_but() has been
acked by Yury.

I've also picked up some CPU errata workarounds since tagging this, so
I'll aim to send those next week.

Cheers,

Will

  Merge branch 'for-next/tlbi' into for-next/core (2024-05-09 15:56:26 +0100)

----------------------------------------------------------------
arm64 updates for 6.10

ACPI:
* Support for the Firmware ACPI Control Structure (FACS) signature
  feature which is used to reboot out of hibernation on some systems.

Kbuild:
* Support for building Flat Image Tree (FIT) images, where the kernel
  Image is compressed alongside a set of devicetree blobs.

Memory management:
* Optimisation of our early page-table manipulation for creation of the
  linear mapping.

* Support for userfaultfd write protection, which brings along some nice
  cleanups to our handling of invalid but present ptes.

* Extend our use of range TLBI invalidation at EL1.

Perf and PMUs:
* Ensure that the 'pmu->parent' pointer is correctly initialised by PMU
  drivers.

* Avoid allocating 'cpumask_t' types on the stack in some PMU drivers.

* Fix parsing of the CPU PMU "version" field in assembly code, as it
  doesn't follow the usual architectural rules.

* Add best-effort unwinding support for USER_STACKTRACE

* Minor driver fixes and cleanups.

Selftests:
* Minor cleanups to the arm64 selftests (missing NULL check, unused
  variable).

Miscellaneous
* Add a command-line alias for disabling 32-bit application support.

* Add part number for Neoverse-V2 CPUs.

* Minor fixes and cleanups.
