4.1-stable review patch. If anyone has any objections, please let me know.
------------------ From: Bjorn Helgaas <[email protected]> commit 45ea2a5fed6dacb9bb0558d8b21eacc1c45d5bb4 upstream. Meelis and Helge reported that 3a9ad0b4fdcd ("PCI: Add pci_bus_addr_t") caused HPMCs on A500 and hangs on rp5470. PA-RISC does not set ARCH_DMA_ADDR_T_64BIT, even for 64-bit kernels, so prior to 3a9ad0b4fdcd, we always used 32-bit PCI addresses. After 3a9ad0b4fdcd, we do use 64-bit PCI addresses in 64-bit kernels, and apparently there's some PA-RISC problem related to them.
