I disagree to this and similar changes in this patch: Why do we need to
get rid of the ENDPROC() here? It's a procedure that's being ended, and
using ENDPROC() is the only (existing) way to mark something as a
procedure in assembly code.

And btw., while described so in the patch comment, this change has nothing
to do with the subject of the patch.
