Hi Linus,

Please pull the arm64 updates below for 6.5. Notable features are
user-space support for the memcpy/memset instructions and the permission
indirection extension. Depending on the order you receive/merge the pull
requests, there is a conflict in linux-next for Documentation/arm64/
(Jon is moving those files under Documentation/arch/) and another
trivial conflict with the kvmarm tree (I think Oliver already pulled
some of the relevant arm64 branches where the resolution was not
obvious).

Thanks.

The following changes since commit 44c026a73be8038f03dbdeef028b642880cf1511:

Linux 6.4-rc3 (2023-05-21 14:05:48 -0700)

Merge branch 'for-next/feat_s1pie' into for-next/core (2023-06-23 18:34:16 +0100)

----------------------------------------------------------------
arm64 updates for 6.5:

- Support for the Armv8.9 Permission Indirection Extensions. While this
feature doesn't add new functionality, it enables future support for
Guarded Control Stacks (GCS) and Permission Overlays.

- User-space support for the Armv8.8 memcpy/memset instructions.

- arm64 perf: support the HiSilicon SoC uncore PMU, Arm CMN sysfs
identifier, support for the NXP i.MX9 SoC DDRC PMU, fixes and
cleanups.

- Removal of superfluous ISBs on context switch (following retrospective
architecture tightening).

- Decode the ISS2 register during faults for additional information to
help with debugging.

- KPTI clean-up/simplification of the trampoline exit code.

- Addressing several -Wmissing-prototype warnings.

- Kselftest improvements for signal handling and ptrace.

- Fix TPIDR2_EL0 restoring on sigreturn

- Clean-up, robustness improvements of the module allocation code.

- More sysreg conversions to the automatic register/bitfields
generation.

- CPU capabilities handling cleanup.

- Arm documentation updates: ACPI, ptdump.
