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: commit 7a59ed415f5b57469e22e41fc4188d5399e0b194 Author: Stefani Seibold <stefani@seibold.net> Date: Mon Mar 17 23:22:09 2014 +0100 x86, vdso: Add 32 bit VDSO time support for 32 bit kernel which is new in 3.15.
