      Description

        Currently, method VM_Version::os_uarch_additional_features uses "fgets" to read the contents of /proc/cpuinfo, then calls "parse_satp_mode" with a string with the leading "mmu" and whitespaces removed, like ": sv39\n". However, "parse_satp_mode" compares this string directly to "sv39", which always fails and returns VM_MBARE.

        Xing Qizheng(@MaxXSoft) will own this issue.
