Thanks for reporting.

I tried to reproduce with above steps, while failed with below message.
Later I got a s390x machine to reproduce the failure, and made a fix in
below patch.

 GENERIC_IOREMAP
Content-type: text/plain

We should always include <asm/io.h> in ARCH, but not <asm-generic/io.h>
directly. Otherwise, macro defined by ARCH won't be seen and could cause
building error.
