This extends the KVM RISC-V ONE_REG interface to report more ISA extensions namely: Zbz, scalar crypto, vector crypto, Zfh[min], Zihintntl, Zvfh[min], and Zfa.
This series depends upon the "riscv: report more ISA extensions through hwprobe" series.from Clement. (Link: https://lore.kernel.org/lkml/20231114141256.126749-1-cleger@rivosinc.com/)
To test these patches, use KVMTOOL from the riscv_more_exts_v1 branch at: https://github.com/avpatel/kvmtool.git
