As another poster said it is 1024MB-128MB. The 1024MB comes from the
user:kernel address space split which the kerneltrap article describes
well. The 128MB is for a special kernel area of memory which, among
other things, allows the kernel to have temporary windows into the areas
above 896MB. The size itself isn't important and is actually a
tunable.
