# 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. # # Fixes: 1a472c9dba6b ("powerpc/mm/radix: Add tlbflush routines") #
