[PATCH 05/15] KVM: x86: Uncondtionally skip MMU sync/TLB flush in MOV CR3's PGD switch

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Stop leveraging the MMU sync and TLB flush requested by the fast PGD
switch helper now that kvm_set_cr3() manually handles the necessary sync,
frees, and TLB flush.  This will allow dropping the params from the fast
PGD helpers since nested SVM is now the odd blob out.
