Description

Similar to the option for Kernel PTI on system_advanced_misc.php we should have an option for MDS.

It is controlled by sysctl oid hw.mds_disable:

0 - mitigation disabled
1 - VERW instruction (microcode) mitigation enabled
2 - Software sequence mitigation enabled (not recommended)
3 - Automatic VERW or Software selection

Also in the system info widget on the Dashboard, the value of hw.mds_disable_state can be output to show the current state.
