I agree with that. Robert P. J. Day pointed out something similiar. For
a more verbose answer to that see the reply to his message.

I totally agree with that. Here's a new patch that totally removes the ACPI_FADT_INFO_ENTRIES
macro. In contrast to the original patch, this one only affects tbfadt.c (I split this, because
there's another issue about rsdump.c pointed out by Robert P. J. Day. The other
changes will be in a reply to his message)
Tested by compilation.
