Hmm ... why is my Intel system missing 'IBPB' & 'IBRS_FW' ?
$ grep . /sys/devices/system/cpu/vulnerabilities/*
/sys/devices/system/cpu/vulnerabilities/meltdown:Mitigation: PTI
/sys/devices/system/cpu/vulnerabilities/spectre_v1:Mitigation: __user pointer
sanitization
/sys/devices/system/cpu/vulnerabilities/spectre_v2:Mitigation: Full generic
retpoline
Are there some kernel options I should have selected manually?
