Thanks Shiozaki-san, I think `reg' is short for registers of the
target chip, correct?  In ACPI's case, PM1 register and some such
and maybe definitions for ACPI tables.
How about kernel/userland shareable stuff like ioctl?  for example,
usb(4) has this kind of definitions in dev/usb/usb.h, not in usbreg.h.
Is this a special case violating the guideline?
I think we can distinguish them like "usb.h" and <dev/usb/usb.h>,
also we will stop generating acpi.h in kernel build directory.

Thanks
