Are you sure? We hit this bug before, but that was fixed by:

25aac9dc7c8c73798c1be8aa36141f980d32579e
ftrace, ia64: explictly ignore a file in recordmcount.pl

Basically what is happening in ftrace.o is that we have:

	ftrace_make_nop(mod, rec, mcount);

That reference to "mcount" will be in the relocation table. The perl
script simply fixes this by not processing the files "ftrace.c". I can
add the same to the C code which should fix this.

Patch soon.
