Back in the days when the kernel was single threaded, testing
"vm_paging_target() > 0" was a reasonable way of determining if the
inactive queue scan met its target. However, now that other threads
can be allocating pages while the inactive queue scan is running, it's
an unreliable method. The effect of it being unreliable is that we
can start swapping out processes when we didn't intend to.
This issue has existed since the kernel was multithreaded, but the
changes to the inactive queue target in 10.0-RELEASE have made its
effects visible.
This change introduces a more direct method for determining if the
inactive queue scan met its target that is not affected by the actions
of other threads.
The UEFI framebuffer driver vt_efifb requires vt(4), so add a
mechanism for the startup routine to set the preferred console.
This change is ugly because console init happens very early in the
boot, making a cleaner interface difficult. This change is intended
only to facilitate the sc(4) / vt(4) transition, and can be reverted
once vt(4) is the default.

r268982: Don't pass null kmdp to preload_search_info
Allow efifb to be used with xf86-video-scfb. This is important for EFI
systems without either a CSM or real graphics drivers, such as my
Lenovo Haswell laptop.
This provides working X with the small complication of a console
cursor permanently overlaid on the upper-left corner of the screen
that will be dealt with later.
r268771:
Allow console drivers active from early boot to be used with
xf86-video-scfb, rather than only drivers attached later on. This
involves a small amount of code duplication with dev/fb/fbd.c, which
will fixed later on.
Also improve performance of vt_blank() by making it not read from the
framebuffer unnecessarily.
On my Lenovo laptop, the firmware maps the EFI framebuffer with MTRRs
set to uncacheable. This leads to execrable console performance. Once
PMAP is up, remap the framebuffer as write-combining. This reduces
boot time on my laptop by 60% when booting with EFI.
The SHT range 0x70000000-0x7fffffff is processor-specific. Pass the

Change libatf-c and libatf-c++ to be private libraries.
We should not be leaking these interfaces to the outside world given
that it's much easier for third-party components to use the devel/atf
package from ports.
As a side-effect, we can also drop the ATF pkgconfig and aclocal files
from the base system. Nothing in the base system needs these, and it
was quite ugly to have to get them installed only so that a few ports
could build. The offending ports have been fixed to depend on
devel/atf explicitly.

r267172:
Homogenize libatf-* version numbers with upstream.
The libatf-* major version numbers in FreeBSD were one version ahead of
upstream because, when atf was first imported into FreeBSD, the upstream
numbers were not respected. This is just confusing and bound to cause
problems down the road.
Fix this by taking advantage of the fact that libatf-* are now private
and that atf is not yet built by default. However, and unfortunately, a
clean build is needed for tests to continue working once "make
delete-old-libs" has been run; hence the note in UPDATING.
