Andy Lutomirski 368b69a5b0 x86, vdso: Fix an OOPS accessing the HPET mapping w/o an HPET 
The oops can be triggered in qemu using -no-hpet (but not nohpet) by
running a 32-bit program and reading a couple of pages before the vdso.
This should send SIGBUS instead of OOPSing.

The bug was introduced by:
