Larger kalloc sizes

I've googled around a bit and couldn't find any talk on larger alloc
sizes, I'm currious about the include/linux/kmalloc_sizes.h and if I
have MMU is there anything bad (except for low memory situations)
forcing the kernel to have those higher memory sizes?

Specifically removing the ifdefs so that they are enabled?
