Subject[BENCHMARK] 2.5.44-mm1 with contest
Here are contest 0.51 benchmarks for 2.5.44-mm1 with shared pagetables enabled:

noload:
Kernel [runs] Time CPU% Loads LCPU% Ratio
2.5.43-mm2 [2] 73.4 93 0 0 1.03
2.5.44 [3] 74.6 93 0 0 1.04
2.5.44-mm1 [3] 75.0 93 0 0 1.05

process_load:

2.5.43-mm2 [2] 105.8 71 44 31 1.48
2.5.44 [3] 90.9 76 32 26 1.27
2.5.44-mm1 [3] 191.5 36 168 64 2.68

These were all checked to ensure it was not one pathological run making the
value high. The range was 190.6->192.7.

2.5.44 [3] 99.1 71 1 21 1.39
2.5.44-mm1 [3] 96.5 74 1 22 1.35

mem_load:

2.5.43-mm2 [2] 106.5 69 27 2 1.49
2.5.44 [3] 114.3 67 30 2 1.60
2.5.44-mm1 [3] 159.7 47 38 2 2.24

Notably different results in many places. This is a similar pattern to the last
time I enabled shared pagetables. I haven't had the time to try without it
enabled yet.
