In a way, both; it is no longer present in memcpy.S because that file now uses
the shared implementation from copy_template.S but that particular line was
fixed in the same way (and funnily enough with a similar commit message) more
than 2 years ago in baf2df8e15be22b8bd24bdd6fd4575b6641bcfd1 ("ARM: 8827/1: fix
argument count to match macro definition").

Therefore, re-syncing would certainly solve the issue.
