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.
