According to IANA RPC uaddr registry, there are no AFs
except IPv4 and IPv6, so it's not worth being too abstract here.
Remove ne_rtable[AF_MAX+1] and use explicit per-AF radix tries.
Use own initialization without relying on domattach code.
While I admit that this was one of the rare places in kernel
networking code which really was capable of doing multi-AF
without any AF-depended code, it is not possible anymore to
rely on dom* code.
While here, change terrifying "Invalid radix node head, rn:" message,
to different non-understandable "netcred already exists for given addr/mask",
but less terrifying. Since we know that rn_addaddr() returns NULL if
the same record already exists, we should provide more friendly error.

A simple continuous read string test using libusb showed a reduction

vt(4) is a new console driver which brings features such as:
o Support for Unicode and double-width characters
o Integration with the KMS kernel video drivers
o Support for UEFI
You may need to update your console settings in /etc/rc.conf, most
probably the keymap. During boot, /etc/rc.d/syscons will indicate what
you need to do.
vt(4) still has issues and lacks some features compared to syscons(4).
See the wiki for up-to-date information:
https://wiki.freebsd.org/Newcons
If you want to keep using syscons(4), you can do so by adding the
following line to /boot/loader.conf:
kern.vty=sc

875. This intersects with the agp_i810.c, which supports all Intels
from i810 to Core i5/7. Both agp_intel.c and agp_i810.c are compiled
into kernel when device agp is specified in config, and agp_i810
attach seems to be selected by chance due to linking order.
Strip support for 810 and later from agp_intel.c. Since 440-class
chipsets do not support any long-mode capable CPUs, remove agp_intel.c
from amd64 kernel file list. Note that agp_intel.c is not compiled
into agp.ko on amd64 already.

By default, vt(4) gets the "preferred mode" from DRM, when using a DRM
video driver as its backend. The preferred mode is usually the native
screen resolution.
Now, if this mode isn't appropriate, a user can use loader tunables to
select a mode. The tunables are read in the following order:
1. kern.vt.fb.modes.$connector_name
2. kern.vt.fb.default_mode
For example, to set a 1024x768 mode, no matter the connector:
kern.vt.fb.default_mode="1024x768"
To set a 800x600 mode only on the laptop builtin screen:
kern.vt.fb.modes.LVDS-1="800x600"

Currently sizeof(struct filedesc0) is 1096 bytes, which means allocations from

There is no easy way to shrink the structure <= 1024 an it is likely to grow in

random_adaptors_lock is held.
- Use sx_sleep instead of tsleep in read and write path to allow
another thread that registers a new random adapter when waiting.
Assert that random_adaptor is not NULL after reacquiring the lock.
- Capture EINTR/ERESTART from sx_sleep to allow the blocking cycle be
stopped when user requests so, while there also make short
read/write's return 0.
- Move M_WAITOK allocations out of lock scope.

support for AVX on i386.
- Similar to amd64, move the FPU save area out of the PCB and instead
store saved FPU state in a variable-sized buffer after the PCB on the
stack.
- To support the variable PCB location, alter the locore code to only use
the bottom-most page of proc0stack for init386(). init386() returns
the correct stack pointer to locore which adjusts the stack for thread0
before calling mi_startup().
- Don't bother setting cr3 in thread0's pcb in locore before calling
init386(). It wasn't used (init386() overwrote it at the end) and
it doesn't work with the variable-sized FPU save area.
- Remove the new-bus attachment from npx. This was only ever useful for
external co-processors using IRQ13, but those have not been supported
for several years. npxinit() is now called much earlier during boot
(init386()) similar to amd64.
- Implement PT_{GET,SET}XSTATE and I386_GET_XFPUSTATE.
- npxsave() is now only called from context switch contexts so it can
use XSAVEOPT.
