[PATCH 1/4] x86,vdso: Fix an OOPS accessing the hpet mapping w/o an hpet

2014-05-19 Thread Andy Lutomirski
The oops can be triggered in qemu using -no-hpet (but not nohpet) by reading a couple of pages past the end of the vdso text. This should send SIGBUS instead of OOPSing. The bug was introduced by: commit 7a59ed415f5b57469e22e41fc4188d5399e0b194 Author: Stefani Seibold Date: Mon Mar 17
