Use 16Kb for kernel stacks instead of 8Kb

└─> Use 16Kb for kernel stacks instead of 8Kb

If you say Y here the kernel will use a 16Kb stacksize for the
kernel stack attached to each process/thread. The default is 8K.
This increases the resident kernel footprint and will cause less
threads to run on the system and also increase the pressure
on the VM subsystem for higher order allocations.
