This should produce no visible changes unless the device is

for the bio for swapout write. It allows the page allocator to drain
free page list deeper. As result, a deadlock where pageout deamon sleeps
waiting for bio to be allocated for swapout is no more reproducable in
practice.
Alan said that M_USE_RESERVE shall be ressurrected and used there, but
until this is implemented, M_NOWAIT does exactly what is needed.

Both situations could cause NULL dereference in the

Namely, cdp->cdp_c.si_parent may be NULL.

Initialize %ds, %es, and %fs during CPU startup. Otherwise a garbage

CPU after exec and the new CPU had never exec'd a 32-bit process.
A more complete fix is needed, but this mitigates the most frequent

When setting media, don't error out when a specific media is selected.
# Note: There may be some issues still here since the EtherJet PC Card doesn't

Also, add a /* bad! */ comment to a 1/2 second delay after we set the
DC/DC parameters. This should be a *sleep of some sort for !cold.
Fortunately it is the only one and is only used when setting media, so
the benefit from removing it is small. Unfortunately, it likely
serves as an exemplar of good programming techniques, which it isn't.

socket support. These utility routines are used only for routing and
pfkey sockets, neither of which have a notion of address, so were
required to mock up fake socket addresses to avoid connection
requirements for applications that did not specify their own fake
addresses (most of them).
Quite a bit of the removed code is #ifdef notdef, since raw sockets
don't support bind() or connect() in practice. Removing this
simplifies the raw socket implementation, and removes two (commented
out) uses of dtom(9).
Fake addresses passed to sendto(2) by applications are ignored for
compatibility reasons, but this is now done in a more consistent way
(and with a comment). Possibly, EINVAL could be returned here in
the future if it is determined that no applications depend on the
semantic inconsistency of specifying a destination address for a
protocol without address support, but this will require some amount
of careful surveying.
NB: This does not affect netinet, netinet6, or other wire protocol
raw sockets, which provide their own independent infrastructure with
control block address support specific to the protocol.
