Hi Linus,

Aside from the usual things this has an arch update for
__iowrite64_copy() used by the RDMA drivers. This API was intended to
generate large 64 byte MemWr TLPs on PCI. These days most processors
had done this by just repeating writel() in a loop. S390 and some new
ARM64 designs require a special helper to get this to generate.

Thanks,
Jason
