Commit Message

Frediano Ziglio Nov. 6, 2024, 1:06 p.m. UTC
The "base" and "offset" definition were inverted, "base" file
should be the files without offsets applied while "offset" should
have the offsets applied.
Also update an old usage of "final" to "apply offset" to make
more clear and consistent (in former commit messages the "final"
term was used instead of "offset").

Fixes: aa9045e77130 ('x86/boot: Rework how 32bit C is linked/included for early boot')

Anthony was right, it was the opposite
