Aneesh Kumar K.V a5d4b5891c powerpc/mm: Fixup tlbie vs store ordering issue on POWER9 ... On POWER9, under some circumstances, a broadcast TLB invalidation might complete before all previous stores have drained, potentially allowing stale stores from becoming visible after the invalidation. This works around it by doubling up those TLB invalidations which was verified by HW to be sufficient to close the risk window. This will be documented in a yet-to-be-published errata.
