As ioread8() is mapped to readb() (I/O memory space), not inb() (I/O
port space),
ioread8_rep() should map to readsb() (which m32r doesn't have yet
BTW), not insb().
For m32r this does matter, as inb() and readb() use different mechanisms
internally.
It seems include/asm-generic/io.h also has this wrong?
