slab_test, before:

10000 times kmalloc(16) -> 68 cycles kfree -> 109 cycles
10000 times kmalloc(32) -> 76 cycles kfree -> 119 cycles
10000 times kmalloc(64) -> 88 cycles kfree -> 114 cycles

After:
10000 times kmalloc(8) -> 60 cycles kfree -> 74 cycles
10000 times kmalloc(16) -> 63 cycles kfree -> 78 cycles
10000 times kmalloc(32) -> 72 cycles kfree -> 85 cycles
10000 times kmalloc(64) -> 91 cycles kfree -> 99 cycles

Erm... The fastpath was not touched and the tests primarily exercise the
fastpath. This is likely some artifact of code placement by the compiler?
