This change is a bad idea. Its called "addressing" because that is what
it is about (see SATA and ATA specs). In future SATA addressing becomes
a 0,1,2 value because 48bits isnt enough, it may get more forms beyond
that.

Might be worth defining ADDR_LBA48, ADDR_LBA28 etc to make it clearer,
but really people shouldnt be randomly hacking IDE code without having
read the specifications.
