<duckinator> Is there any reason OSes tend to map the kernel at >3GB in memory?
<geist> duckinator: are you asking why do they map it up high, or specifically why 3gb?
<duckinator> geist: whichever is easier to answer
<geist> or why do they map the kernel at all?
<geist> a bunch of seperate questions, actually
<duckinator> why it's high - why not have it low and put everything else above it?
<geist> you can do that too. BeOS did
<duckinator> so it's just an odd little tradition?
<geist> some architectures require it
<geist> some dont require any mapping of the kernel at all
