Justin Hibbits 009dedabb3 Knock a page off VM_MAX_KERNEL_ADDRESS
There are places where checks are made against VM_MAX_KERNEL_ADDRESS, or
virtual_end (set to VM_MAX_KERNEL_ADDRESS).  With 32-bit checks, an address will
always be less than or equal to 0xffffffff.  Drop a page, so those checks can
terminate loops safely.
