[Intel-gfx] Is MI_FLUSH_ENABLE bit 12?

Just reading through vol1c.4 of the bspec  this evening and found something odd.

Bit 11 of MI_MODE is "Invalidate UHPTR enable".
Bit 12 of MI_MODE is "MI_FLUSH Enable"

And, yet, in i915_reg.h:

#define MI_MODE		0x0209c
# define VS_TIMER_DISPATCH				(1 << 6)
# define MI_FLUSH_ENABLE				(1 << 11)

Are we off-by-one on MI_FLUSH_ENABLE? Seems like this would cause
serious problems...
