Use UMA_ALIGN_PTR instead of sizeof(void *) for zone alignment.
uma_zcreate()'s alignment argument is supposed to be sizeof(foo) - 1, and uma.h provides a set of helper macros for common types. Passing sizeof(void *) results in all of the members being misaligned triggering unaligned access faults on certain architectures (notably MIPS).
