Merge tag 'riscv-for-linus-6.9-mw2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V updates from Palmer Dabbelt:
- Support for various vector-accelerated crypto routines
- Hibernation is now enabled for portable kernel builds
- mmap_rnd_bits_max is larger on systems with larger VAs
- Support for fast GUP
- Support for membarrier-based instruction cache synchronization
- Support for the Andes hart-level interrupt controller and PMU
- Some cleanups around unaligned access speed probing and Kconfig
settings
- Support for ACPI LPI and CPPC
- Various cleanus related to barriers
- A handful of fixes
