PowerPC failed to handle broadcast TLB flush operations. Executing instructions that are defined architecturally as synchronizing global TLB should have a global effect.
* tlbie on BookS * tlbivax on BookE * H_CALLs (H_REMOVE, H_BULK_REMOVE and H_PROTECT) in case of pseries, since they contain a tlbie on a real hypervisor. The implementation provides a single point that can be used in MTTCG for doing async-flushes. The patchset introduces bit-flags in CPUPPCState::tlb_need_flush: TLB_NEED_LOCAL_FLUSH (0x1) - Flush local tlb TLB_NEED_GLOBAL_FLUSH (0x2) - Flush tlb on other cpus.
