Pekka Paalanen 3e61e0c976 mmiotrace broken in linux-next (8-bit writes only) 
The moment mmiotrace is enabled, I hit a NULL deref in:

IP: [<ffffffff80256e71>] __trace_special+0x17c/0x23a
Call Trace:
 [<ffffffff802573cc>] ftrace_special+0x6f/0x9a
 [<ffffffff8023e3e4>] down+0x19/0x4a
 [<ffffffff80228adc>] acquire_console_sem+0x42/0x58
 [<ffffffff8035d273>] con_flush_chars+0x28/0x43
 [<ffffffff80354a70>] write_chan+0x22e/0x334
 [<ffffffff802244e9>] ? default_wake_function+0x0/0xf
 [<ffffffff8035236d>] tty_write+0x195/0x228
 [<ffffffff80354842>] ? write_chan+0x0/0x334
 [<ffffffff8027c23a>] vfs_write+0xae/0x137
 [<ffffffff8027c6e3>] sys_write+0x47/0x70
 [<ffffffff8020b1db>] system_call_after_swapgs+0x7b/0x80

which means 'entry' in __trace_special() is NULL.

[ mingo@elte.hu: that ftrace_special() was a leftover. ]
