Bahadir Balban afc0599d49 Saving all registers in syscall so that return from fork is easier. ...

Child needs rewound function stack in order to reach registers r9-r12
that have original userspace values. But we jump to return_from_syscall
without rewinding the stack. Therefore to ease context restore, we save
r9-r12 on the stack as well upon syscall entry.
