Sean Christopherson a835429cda KVM: x86/mmu: Ensure TLBs are flushed when yielding during GFN range zap ... When flushing a range of GFNs across multiple roots, ensure any pending flush from a previous root is honored before yielding while walking the tables of the current root. Note, kvm_tdp_mmu_zap_gfn_range() now intentionally overwrites its local "flush" with the result to avoid redundant flushes. zap_gfn_range() preserves and return the incoming "flush", unless of course the flush was performed prior to yielding and no new flush was triggered.
