Sebastian Ott 4f5359e94b s390/pci_dma: make lazy flush independent from the tlb_refresh bit ... We have 2 strategies to reduce the number of RPCIT instructions: * A HW feature indicated via the tlb_refresh bit allows us to omit RPCIT for invalid -> valid translation-table entry updates. * With "lazy flush" we omit RPCIT for valid -> invalid updates until we run out of dma addresses. When we have to reuse dma addresses we issue a global tlb flush using only one RPCIT instruction. Currently lazy flushing depends on tlb_refresh. Since there is no technical reason for this remove this dependency.
