Modified Files: src/sys/arch/i386/conf: GENERIC Log Message: Disable vm86 by default. The use case is limited, and the potential for damage is too high. This code is fragile, and relies on a certain number of assumptions, some of which are not be totally true. For example, it relies on the fact that a 16bit process cannot perform a syscall, but verily it can. The slighest confusion in the trap frame can lead to ring0 exploits. Also, I'm not convinced that it interacts well with the compatibility layers.
