The declaration of dmi helper functions is a bit messy and inconsistent at the moment: * On ia64 they are declared in <asm/io.h>. * On x86-64 they are declared in <asm/dmi.h>. * On i386 they are declared both in <asm/io.h> and <asm/dmi.h>. Fix the header files so that the dmi helper functions are consistently defined in <asm/dmi.h>.
