ftrace: fix lockup with MAXSMP

Browse source 
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.
