So can you, by use of arcane tool known as "grep"... It's in kernel/softirq.c
and that's genksyms parser being fucked in head. Look for TYPEOF_KEYW
in parse.y and you'll see. Especially amusing part is a kludge from
commit a89a0a2354ae666612968e254d650bfd04f11eb6...

2.18.50.0.6.

And no, it's not tools side. What it is, AFAICT, is that sparc32 has
LDFLAGS_vmlinux = -r, which leaves a metric arseload of relocs that
wouldn't have survived into vmlinux otherwise. Look at .rela__ksymtab
in .tmp_vmlinux1, for example...
