WebCONFIG_X86_IOPL_IOPERM=n. Disable legacy iopl(2) and ioperm(2) system calls, which should not be used by modern userspace anymore. CONFIG_MICROCODE=y. Needed to benefit from microcode updates and thus security fixes (e.g., additional Intel pseudo-MSRs to be used by the kernel as a mitigation for various speculative execution vulnerabilities).
