I see. Back to the patch, can't you replace vmx->eptp by
construct_eptp(vcpu->arch.mmu.root_hpa)?
Modified follow Avi's advice. Sorry for miss the mail...

Subject: [PATCH] KVM: VMX: Add ept_sync_context in flush_tlb
Fix a potention issue caused by kvm_mmu_slot_remove_write_access().
The
old behavior don't sync EPT TLB with modified EPT entry, which result
in inconsistent content of EPT TLB and EPT table.
Applied, thanks.

I added a forward declaration rather than move the code to make it clear
there are no changes here.
