This change causes my 2-cpu, x86-64 VirtualBox VM to hang hard
immediately on boot, regardless of how I build the kernel. If I build
the kernel with DEBUG, it hangs immediately after printing
"kernel text is mapped with 6 large pages and 442 normal pages".
In fact, it hangs so hard that it makes VirtualBox throw a fatal error
when I try to reset the VM.
I understand this change is _not_ causing trouble for some others, but
it sure does for me. Can we back it out temporarily, and what can I
offer by way of help in debugging it?
