[Qemu-ppc] [PATCH v4 0/3] ppc: handle broadcast tlb flush |

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.
Changelog
v3:
* Updated commit messages and cover letter(benh)
Nikunj A Dadhania (3):
target-ppc: add TLB_NEED_LOCAL_FLUSH flag
target-ppc: add flag in chech_tlb_flush()
target-ppc: tlbie/tlbivax should have global effect
