Hi Linus,
Please pull the arm64 updates below for 6.9-rc1. The major features are
support for LPA2 (52-bit VA/PA with 4K and 16K pages), the dpISA
extension and Rust enabled on arm64. The changes are mostly contained
within the usual arch/arm64/, drivers/perf, the arm64 Documentation and
kselftests. The exception is the Rust support which touches some generic
build files.
There are two last-minute reverts: enabling CPUMASK_OFFSTACK on arm64
seems to have caused some issue with the cpufreq/opp drivers (still
debugging); the other is SCTLR_EL1.WXN hardening on arm64, the feature
is no longer applicable with permissions indirection, so the approach
needs revisiting.
So far there's a single conflict with your tree in rust/Makefile:

I'll expect one or two more conflicts with the KVM tree when that gets
pulled in but the resolutions in -next are correct.
Thanks.

Revert "mm: add arch hook to validate mmap() prot flags" (2024-03-13 10:59:38 +0000)
----------------------------------------------------------------
arm64 updates for 6.9:
* Reorganise the arm64 kernel VA space and add support for LPA2 (at
stage 1, KVM stage 2 was merged earlier) - 52-bit VA/PA address range
with 4KB and 16KB pages
* Enable Rust on arm64
* Support for the 2023 dpISA extensions (data processing ISA), host only
* arm64 perf updates:
- StarFive's StarLink (integrates one or more CPU cores with a shared
L3 memory system) PMU support
- Enable HiSilicon Erratum 162700402 quirk for HIP09
- Several updates for the HiSilicon PCIe PMU driver
- Arm CoreSight PMU support
- Convert all drivers under drivers/perf/ to use .remove_new()
* Miscellaneous:
- Don't enable workarounds for "rare" errata by default
- Clean up the DAIF flags handling for EL0 returns (in preparation for
NMI support)
- Kselftest update for ptrace()
- Update some of the sysreg field definitions
- Slight improvement in the code generation for inline asm I/O
accessors to permit offset addressing
- kretprobes: acquire regs via a BRK exception (previously done via a
trampoline handler)
- SVE/SME cleanups, comment updates
- Allow CALL_OPS+CC_OPTIMIZE_FOR_SIZE with clang (previously disabled
due to gcc silently ignoring -falign-functions=N)
