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

 489           0, the base of the address space. And this is the default. Some

 514           Typically on m68k systems the kernel will not start at the base
 515           of RAM, but usually some small offset from it. Define the start
 516           address of the kernel here. The most common setup will have the
 517           processor vectors at the base of RAM and then the start of the
 518           kernel. On some platforms some RAM is reserved for boot loaders
 519           and the kernel starts after that. The 0x400 default was based on
 520           a system with the RAM based at address 0, and leaving enough room
 521           for the theoretical maximum number of 256 vectors.
