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.
