Initial commit
block: cfq: definitely finally nail the CFQ tunables.
One final tweak to give us the desired 335, 85 on tuna, according to pkgnex's Excel GN equation which accomodates for the weird HZ: y=TRUNC(x*7.8125,0)
arch: omap: export current IVA clock to userspace, make GPU+IVA exports match
similar to scaling_cur_freq, gpu_cur_freq and iva_cur_freq
