Oops, apologies this is my mistake! The AArch4 code was cloned off the
ppc code and I when I looked at the ppc versions this morning I saw they
included the same repeated call to start_a_stub that you removed from
the AArch64 tree. Evidently I was still high on crack from last night's
Dionysian debauch (or something like that :-) since, as you say, there
is no such call.

I'll just go get another cup of coffee . . .
