|Here is an excerpt from Peter Van Der Linden's excellent "Expert C

This brings me to something else that I have seen.. pagefaults... when I
looked up on the net I saw an explaination similiar to the one above.
When I compile a kernel... if I "time" it.... I get about a million minor
and major pagefaults....
even a simple ls gives me
0.01user 0.00system 0:00.06elapsed 15%CPU (0avgtext+0avgdata
0maxresident)k 0inputs+0outputs (153major+104minor)pagefaults 0swaps
(pretty large directory though)
But a seach or google returned some results where somepeople have managed
to compile a kernel with *ZERO* pagefaults!
Is there anyways to fix these bus errors and pagefaults ??
