It has cropped up here a few times so this is a notice, I won't renew it. I think it has served its goal ; nowadays everyone concerned should be running a kernel that supports mitigations=off or a CPU with hardware mitigations.

Can you elaborate? Will a modern kernel effectively do all of these flags if passed migration=off?

  noibrs noibpb nopti nospectre_v2 nospectre_v1 l1tf=off nospec_store_bypass_disable no_stf_barrier mds=off tsx=on tsx_async_abort=off mitigations=off
Thanks for the excellent project. I've been doing this for a long while now. Much appreciated.

mitigations=off, and if the kernel devs do their job correctly, yes
