Also, this turns an easily understood and widely documented kernel panic
message into a page fault.  Prior to this, users could google for the
message and find documentation on increasing the size of the kernel
address space.  Now, it requires facility with the source code in order to
figure out what it is going on (since the page fault trace won't include
the memory allocation).
