These emails are auto generated by bot.  I just look over the email and
verify it looks reasonable.  Moving the code around sometimes makes it
show up as a new bug.  Also changes to the Kconfig file can affect which
code is checked.

The commit that you mention does not generate a warning.  The warning
started in commit 025dceb0fab3 ("bpf: powerpc64: optimize JIT passes for
bpf function calls").
