The Linux kernel has just received its mitigation work for the newly-announced TSX Asynchronous Abort (TAA) variant of ZombieLoad plus revealing mitigations for another Intel CPU issue... So today in addition to the JCC Erratum and ZombieLoad TAA the latest is iITLB Multihit (NX) - No eXcuses...

Ffs, they're massacring our boy. Alternative headline: "Linux kernel under attack by Intel mitigations."

Linus do something!!

Brace yourselves! Law suits are coming!

Hah. How awesome.. Just hours after my rant that a endless pile of fixes to crap architectural issues making it to core Linux stuff...
So. Here we go again.

Revive Transmeta?

Is there a total list of CPU vulnerabilities and their overall impact?

Sadly, no benchmarks.

Jesus i wouldn't wanna be at Intel Security Department. At this rhythm the I9-9900KS IPC will match bulldozer's

Now it makes benchmark between different operating system less valuable. How can we be sure if non Open Source systems use full mitigations?
