Linus Torvalds e0152e7481 RISC-V Patches for the 6.6 Merge Window, Part 1 
* Support for the new "riscv,isa-extensions" and "riscv,isa-base" device
   tree interfaces for probing extensions.
 * Support for userspace access to the performance counters.
 * Support for more instructions in kprobes.
 * Crash kernels can be allocated above 4GiB.
 * Support for KCFI.
 * Support for ELFs in !MMU configurations.
 * ARCH_KMALLOC_MINALIGN has been reduced to 8.
 * mmap() defaults to sv48-sized addresses, with longer addresses hidden
   behind a hint (similar to Arm and Intel).
 * Also various fixes and cleanups.
