- substituted the use of the m_source message field by caller->p_endpoint in kernel calls. It is the same information, just passed more intuitively. - the last dependency on m_type field is removed. - do_unused() is substituted by a check for NULL. - this pretty much removes the depency of kernel calls on the general message format. In the future this may be used to pass the kcall arguments in a different structure or registers (x86-64, ARM?) The kcall number may be passed in a register already.
