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) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux tags/arm64-upstream for you to fetch changes up to abc17128c81ae8d6a091f24348c63cbe8fe59724: 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.
