* While x86 architecture in general requires an IPI to perform TLB
* shootdown, enablement code for several hypervisors overrides
* .flush_tlb_others hook in pv_mmu_ops and implements it by issuing
* a hypercall. To keep software pagetable walkers safe in this case we
- * switch to RCU based table free (HAVE_RCU_TABLE_FREE). See the comment
