Jan Glauber 87bc359b98 s390/pci: speed up __iowrite64_copy by using pci store block insn ... Benefit from pci store block instruction by writing up to 128 bytes with a single instruction to MMIO space. Depending on the workload this can result in a huge performance increase due to the reduced number of instructions. The ordering guarantees of single stores vs. one store block are identical.
