A quick grep on the file in question revealed that there are two
functions that may panic() with "page not in any segment": the
vm_phys_paddr_to_vm_page() being patched and also the next function
vm_phys_paddr_to_segind(). I'm not exactly current with the memory
management code so this may be a very stupid question, but I'll ask it
anyway: don't both functions need to be patched?
My apologies if I'm way off the mark here, but I'm just trying to help.
All right, that does it Bill [Donahue]. I'm pretty sure that killing
Jesus is not very Christian.
