Everyone and their mother includes linux/acpi.h, i.e. modifying realmode.h results in a full kernel rebuild, which makes the already inscrutable real mode boot code even more difficult to understand and is positively rage inducing when trying to make changes to x86's boot flow. No functional change intended.
