Add deprecation notices to ce,cp sync serial drivers

2022-12-22T15:47:14+00:00

And the related sconfig utility.  Sync serial (e.g. E1/T1) interfaces
are obsolete, and nobody responded to several inquires on the mailing
lists about use of these drivers.

Use a separate copy of machdep.h in cp and ce drivers

2020-03-20T19:28:55+00:00

Previously they included sys/dev/cx/machdep.h, but the cx driver was
retired in r359178.  These drivers haven't had real development for
a decade or more so there's no real benefit in sharing this file; just
copy it to the ce and cp subdirs.

sys/dev: Replace zero with NULL for pointers.

2017-02-20T03:43:12+00:00

Makes things easier to read, plus architectures may set NULL to something
different than zero.

Most affect comments, very few have user-visible effects.

CALLOUT_MPSAFE has lost its meaning since r141428, i.e., for more than ten

years for head.  However, it is continuously misused as the mpsafe argument
for callout_init(9).  Deprecate the flag and clean up callout_init() calls
to make them more consistent.

In order to reduce use of M_EXT outside of the mbuf allocator and

2015-01-06T12:59:37+00:00

socket-buffer implementations, introduce a return value for MCLGET()
(and m_cljget() that underlies it) to allow the caller to avoid testing
M_EXT itself.  Update all callers to use the return value.

With this change, very few network device drivers remain aware of
M_EXT; the primary exceptions lie in mbuf-chain pretty printers for
debugging, and in a few cases, custom mbuf and cluster allocation
implementations.

NB: This is a difficult-to-test change as it touches many drivers for
which I don't have physical devices.  Instead we've gone for intensive
review, but further post-commit review would definitely be appreciated
to spot errors where changes could not easily be made mechanically,
but were largely mechanical in nature.
