The purpose of this series is to:
- Fix the "BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment" messages reported by Linus [1], Andy [2], and others.
- Move arch-specific shadow ROM location knowledge, e.g., 0xC0000-0xDFFFF, from PCI core to arch code.
- Fix the ia64 and MIPS Loongson 3 oddity of keeping virtual addresses in shadow ROM struct resource (resources should always contain *physical* addresses).
- Remove now-unused IORESOURCE_ROM_COPY and IORESOURCE_ROM_BIOS_COPY flags.
This series is based on v4.5-rc1, and it's available on my pci/resource git branch (along with a couple tiny unrelated patches) at [3].
