- honor parent DMA tag limitations, as man page requires,
- allow data buffer to be allocated within full 64bit address range, when
support is announced by hardware,
- add quirk, disabling 64bit addresses for broken chips, use it for MCP78.
about a queue from a remote host. That remote host may use \r, \r\n,
or \n\r as the line-ending character. In some cases the remote host
will write a single line of information without *any* EOL sequence.
Translate all the non-unix EOL's to the standard newline, and make
sure the final line includes a terminating newline. Logic is also
added to translate all unprintable characters to '?', but that is
#if-ed out for now.

entries allocated for translations in pmap_init() as MAP_NOFAULT. This
prevents vm_map_insert from trying to account the entries for swap
usage, that is both wrong and too early to work.
While there, change FALSE to VMFS_NO_SPACE.

On amd64 KERNBASE/kernbase does not mean start of kernel memory.
This should fix a KASSERT panic in dtrace_copycheck when copyin*()
is used in D program.
Also make checks for user memory a bit stricter.

'ifa' was used as the TAILQ_FOREACH() iterator argument, and 'ia' was just
derived form it, it could be left non-NULL which confused later
conditional freeing code. This could cause kernel panics if multicast IP
packets were received. [1]
Call 'struct in_ifaddr *' in ip_rtaddr() 'ia', not 'ifa' in keeping with
normal conventions.
When 'ipstealth' is enabled returns from ip_input early, properly release
the 'ia' reference.

- at_ifawithnet(), which acquires an locks it needs and returns an
at_ifaddr reference.
- at_ifawithnet_locked(), which relies on the caller locking
at_ifaddr_list, and returns a pointer rather than a reference.
Update various consumers to prefer one or the other, including ether
and fddi output, to properly release at_ifaddr references.
Rework at_control() to manage locking and references in a manner
identical to in_control().

Eliminate an unnecessary #include.
- Modules and kernel code alike may use DPCPU_DEFINE(),
DPCPU_GET(), DPCPU_SET(), etc. akin to the statically defined
PCPU_*. Requires only one extra instruction more than PCPU_* and is
virtually the same as __thread for builtin and much faster for shared
objects. DPCPU variables can be initialized when defined.
- Modules are supported by relocating the module's per-cpu linker set
over space reserved in the kernel. Modules may fail to load if there
is insufficient space available.
- Track space available for modules with a one-off extent allocator.
Free may block for memory to allocate space for an extent.
