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

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

 482           0, the base of the address space. And this is the default. Some

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