 505           If you say Y here the kernel will use a 4Kb stacksize for the
 506           kernel stack attached to each process/thread. This facilitates
 507           running more threads on a system and also reduces the pressure
 508           on the VM subsystem for higher order allocations.

 542           Typically on m68k systems the kernel will not start at the base
 543           of RAM, but usually some small offset from it. Define the start
 544           address of the kernel here. The most common setup will have the
 545           processor vectors at the base of RAM and then the start of the
 546           kernel. On some platforms some RAM is reserved for boot loaders
 547           and the kernel starts after that. The 0x400 default was based on
 548           a system with the RAM based at address 0, and leaving enough room
 549           for the theoretical maximum number of 256 vectors.
