riscv: Optimize bitops with Zbb extension (2023-11-09 10:15:52 -0800)
----------------------------------------------------------------
RISC-V Patches for the 6.7 Merge Window, Part 2
* Support for handling misaligned accesses in S-mode.
* Probing for misaligned access support is now properly cached and
handled in parallel.
* PTDUMP now reflects the SW reserved bits, as well as the PBMT and
NAPOT extensions.
* Performance improvements for TLB flushing.
* Support for many new relocations in the module loader.
* Various bug fixes and cleanups.
