This commit adds support for riscv_hwprobe on the Linux kernel 6.15. It adds feature detection of 8 extensions (4 of them are new in this).

Existing RISC-V Extensions:

  1. Zicntr
  2. Zihpm
  3. Zalrsc
  4. Zaamo

New RISC-V Extensions:

  1. Zicbom
  2. Zfbfmin
  3. Zvfbfmin
  4. Zvfbfwma

Note: four new extensions are already added to beta (cf. rust-lang/rust#140507) and checking cfg should be okay.
