| 2019-11-21 | selftests/x86/mov_ss_trap: Fix the SYSENTER test |   Andy Lutomirski | 1 | -1/+2 | |
| For reasons that I haven't quite fully diagnosed, running mov_ss_trap_32 on a 32-bit kernel results in an infinite loop in userspace. This appears to be because the hacky SYSENTER test doesn't segfault as desired; instead it corrupts the program state such that it infinite loops. Fix it by explicitly clearing EBP before doing SYSENTER. This will give a more reliable segfault.

| This exercises a nasty corner case of the x86 ISA.
