disabled by default because there's problems with it on AT91RM9200,
currently the only host controller in the tree. I've not had time to
track those problems to ground. I'm committing because this is
important for other host controllers that are in the pipeline.

page / NULL returned from pmap_extract_and_hold to determine whether or not vm_fault needs
to be called.

vm_pageout_oom() describing a reason for the call.
Call vm_pageout_oom() from the swp_pager_meta_build() when swap zone

all others. Use this to disambiguate cmd line arguments that can
be either clone params or regular parameters so, in particular,
"bssid" again works as a regular parameter.
While here leverage the above to improve the logic for flushing
clone operations on the first !clone cmd line parameter.

if the probe succeeds. This guarantees that the BSD scheme
wins over the MBR scheme when MBR gets to probe first. Build-
or link-time conditions can cause schemes to end up in the
linker set in a different order. Normally BSD is before MBR
in the linker set and as such get to probe first. But typically
when the kernel gets rebuild or relinked, this can change.
- Document the minor(3), major(3) and makedev(3) macro's. They also
apply to umajor() and uminor() in the kernel, but hopefully we'll sort
that out one day.
- Briefly dev2unit() inside the make_dev(9) manual page, since this is
now the preferred macro to obtain character device unit numbers inside
the kernel.
- Remove the device_ids(9) manual page. It contains highly inaccurate
information, such as a description of the nonexistent major().
sys/param.h and move the MI numbers out of here. Also move the MI
defines. Also remove a couple defines not in use (not sure if it is
age, or OpenBSD origins for thse). Note the current values that are
overrides that appear to be odd in some way.
More cleanup could be done here: NBPG appears to be spelled PAGE_SIZE
these days. There's new ways to spell PGOFSET and PGSHIFT too, I
think. These constants duplicate the MI constants and are sprinkled
into the mips code only. Further investigation is needed.
all to date and the latter also is only used in ia64 and powerpc
code which no longer serves a real purpose after bring-up and just
can be removed as well. Note that architectures like sun4u also
provide no means of implementing IPI'ing a CPU itself natively
in the first place.

Because we now enforce UNIX98-style PTY's, we now use a lot of TTY's
that don't have the traditional /dev/ttyXX naming scheme. pkill(1)'s -t
flag automatically prepended the word "tty" to each TTY that was passed
on the command line. This meant that `pkill -t pts/0' was actually
converted to /dev/ttypts/0. Disable this broken behaviour for now.

There are some lint programs that use this hint to avoid generating
warnings.

JBus to PCI 2.2 bridges. In theory, this driver should also handle
`XMITS' Fireplane/Safari to PCI-X bridges but due to lack of access
to such hardware, support for these hasn't be fleshed out, yet.
