For slab, I found that the following two patches reduce text size most (for i386 NUMAQ config) while keeping UMA path the same. I don't have actual NUMA-capable hardware so I have no way to benchmark them. Both patches move code out-of-line and thus introduce new function calls which might affect performance negatively.
