Revision 048f49809c526348775425420fb5b8e84fd9a133 authored by Sean Christopherson on 25 March 2021, 20:01:18 UTC, committed by Paolo Bonzini on 30 March 2021, 17:19:55 UTC 
KVM: x86/mmu: Ensure TLBs are flushed for TDP MMU during NX zapping
 
Honor the "flush needed" return from kvm_tdp_mmu_zap_gfn_range(), which
does the flush itself if and only if it yields (which it will never do in
this particular scenario), and otherwise expects the caller to do the
flush.  If pages are zapped from the TDP MMU but not the legacy MMU, then
no flush will occur.
