Subject: [PATCH 0/5] x86/vm86: First round of vm86 cleanups

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.
