David Greenman 97e112628f Check for page being resident when doing I/O with /dev/kmem and return 
EFAULT if it is not resident. This prevents the system from manufacturing
a zero-fill page for unused but allocated areas of the kernel's VM. This
should fix the "CMAP busy" panic that some people saw during system
startup.
