This fixes issues like ptrace and syscall auditing not working with vm86, and makes possible cleanups in the syscall exit work code. Changes from v1: - Added first two patches - Changed userspace access to copy each field explicitly instead of relying on the same order of members in the structure. In-Reply-To:
