457 Select the desired split between kernel and user memory.
458
459 If the address range available to the kernel is less than the
460 physical memory installed, the remaining memory will be available
461 as "high memory". Accessing high memory is a little more costly
462 than low memory, as it needs to be mapped into the kernel first.
463 Note that increasing the kernel address space limits the range
464 available to user programs, making the address space there
465 tighter. Selecting anything other than the default 3G/1G split
466 will also likely make your kernel incompatible with binary-only
467 kernel modules.
