syscall related developer documentation

[Stephan <stephanwib%googlemail.com@localhost>]

Hi

I´m reffering to this documentation:

http://www.netbsd.org/docs/internals/en/chap-processes.html#syscall_howto

I do think that some points have changed with current versions of
NetBSD (7, current). For example the format of syscalls.master and the
argument handling.

Could someone familiar check this?

Thanks!
