ftrace: fix lockup with MAXSMP
MAXSMP brings in lots of use of various bitops in smp_processor_id()
and friends - causing ftrace to lock up during bootup:
calling anon_inode_init+0x0/0x130
initcall anon_inode_init+0x0/0x130 returned 0 after 0 msecs
calling acpi_event_init+0x0/0x57
[ hard hang ]
So exclude the bitops facilities from tracing.
