I've finally gotten back to this after several months. This is the 2nd
part of mach/io.h removals. This series removes io.h on platforms with
PCI by creating a fixed virtual I/O mapping and a common __io() macro.

As several platforms have 2 1MB I/O windows, I've changed the fixed
mapping to 2MB (vs. 1MB in the prior posting) and allow platforms to
control the size. This also allows using a single 1MB section mapping
rather than 4KB pages.

Looks really good, feel free to add my Reviewed-by on patches 2-15, since
I've done a line-by-line walkthrough and could not find anything besides the
trivial comments I gave.

Thanks for the review. It's going to change a bit with using
ioremap_page_range. Hope to have new version out soon.

Beware the fact that you can't use ioremap_page_range() early on during 
the boot as it uses the standard page allocator.
