Maybe that exact code path is only reachable on x86/ia64? But if so
please explain why.

Otherwise it looks like this series could break that driver on powerpc
at least.

Indeed.

When I last looked into this, I sent a patch to use ioremap()
on non-x86:

OK thanks.

Baoquan can you add that patch to the start of this series if/when you
post the next version?

Sure, will do. Wondering if we need make change to cover powerpc other
than x86 and ia64 in Arnd's patch as you and Geert pointed out.
