The goal of this set of patches is to change vm86 support to return to userspace with the normal exit paths instead of leaving data on the kernel stack and jumping directly into the exit asm routines. This fixes issues like ptrace and syscall auditing not working with vm86, and makes possible cleanups in the syscall exit work code.
