powerpc/e6500: Work around erratum A-008139 Erratum A-008139 can cause duplicate TLB entries if an indirect entry is overwritten using tlbwe while the other thread is using it to do a lookup. Work around this by using tlbilx to invalidate prior to overwriting. To avoid the need to save another register to hold MAS1 during the workaround code, TID clearing has been moved from tlb_miss_kernel_e6500 until after the SMT section.
