 520           If you say Y here the kernel will use a 4Kb stacksize for the

 522           running more threads on a system and also reduces the pressure

 557           Typically on m68k systems the kernel will not start at the base
 558           of RAM, but usually some small offset from it. Define the start
 559           address of the kernel here. The most common setup will have the
 560           processor vectors at the base of RAM and then the start of the
 561           kernel. On some platforms some RAM is reserved for boot loaders
 562           and the kernel starts after that. The 0x400 default was based on
 563           a system with the RAM based at address 0, and leaving enough room
 564           for the theoretical maximum number of 256 vectors.
