Modified Files: src/sys/arch/i386/i386: i386_trap.S trap.c Log Message: Mitigation for CVE-2018-8897 on i386. Contrary to amd64 there is no clear way to determine if we are in kernel mode but with the user context; so we go the hard way, and scan the IDT. On i386 the bug is less of a problem, since we don't have GSBASE. All an attacker can do is panicking the system.
