[4/6] x86: i386_cons_align() badly affects diagnostics
Checks
Commit Message
Warning without knowing what's going to follow isn't useful, the more
that appropriate warnings are emitted elsewhere in all cases. Not
updating state (file/line in particular) also isn't helpful, as it's
always the last directive ahead of a construct potentially needing
fiddling with that's "guilty" in that fiddling being suppressed.

Maybe the stray diagnostics are the reason why there is that
questionable SEC_CODE check in the function (which for now I'm retaining
there)?
