  KVM: SVM: Don't flush cache if hardware enforces cache coherency across encryption domains (2020-09-19 20:46:59 +0200)

----------------------------------------------------------------
* Add support for hardware-enforced cache coherency on AMD which
obviates the need to flush cachelines before changing the PTE encryption
bit, by Krish Sadhukhan.

* Add Centaur initialization support for families >= 7, by Tony W
Wang-oc.

* Add a feature flag for, and expose TSX suspend load tracking feature
to KVM, by Cathy Zhang.

* Emulate SLDT and STR so that windows programs don't crash on UMIP
machines, by Brendan Shanks and Ricardo Neri.

* Use the new SERIALIZE insn on Intel hardware which supports it, by
Ricardo Neri.

* Misc cleanups and fixes.
