Here are contest results showing 2.5.46-mm1 with preempt enabled. The other
kernels have it disabled.

Much improved

2.5.46 [1] 98.3 80 1 7 1.38
2.5.46-mm1 [5] 95.3 80 1 5 1.33

xtar_load:

2.5.44-mm6 [3] 207.6 37 2 7 2.91
2.5.46 [1] 113.5 67 1 8 1.59
2.5.46-mm1 [5] 227.1 34 3 7 3.18

Whatever was causing this to be high in 2.5.44-mm6 is still there now.

io_load:
Kernel [runs] Time CPU% Loads LCPU% Ratio
2.5.44-mm6 [3] 284.1 28 20 10 3.98
2.5.46 [1] 600.5 13 48 12 8.41
2.5.46-mm1 [5] 134.3 58 6 8 1.88

Big change here. IO load is usually the one we feel the most.

read_load:
Kernel [runs] Time CPU% Loads LCPU% Ratio
2.5.44-mm6 [3] 104.3 73 7 4 1.46
2.5.46 [1] 103.5 75 7 4 1.45
2.5.46-mm1 [5] 103.2 74 6 4 1.45

list_load:
Kernel [runs] Time CPU% Loads LCPU% Ratio
2.5.44-mm6 [3] 95.3 75 1 20 1.33
2.5.46 [1] 96.8 74 2 22 1.36
2.5.46-mm1 [5] 101.4 70 1 22 1.42

mem_load:
Kernel [runs] Time CPU% Loads LCPU% Ratio
2.5.44-mm6 [3] 226.9 33 50 2 3.18
2.5.46 [3] 148.0 51 34 2 2.07
2.5.46-mm1 [5] 180.5 41 35 1 2.53

And this remains relatively high but better than 2.5.44-mm6

Unfortunately I've only run this with preempt enabled so far and I believe
many of the improvements are showing this effect.
