 469           Allow the slab memory allocator to keep chains for very large
 470           memory sizes - upto 32MB. You may need this if your system has
 471           a lot of RAM, and you need to able to allocate very large
 472           contiguous chunks. If unsure, say N.

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

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