displays after a pause, use the difference in runtime divided by the
length of the pause as the percentage of CPU used instead of the value
calculated by the kernel. In addition, when determing if a process or
thread is idle or not, treat any process or thread that has used any
runtime or performed any context switches during the interval as busy.
Note that the percent CPU is calculated as a double and stored in an
array to avoid recalculating the value multiple times in the comparison
method used to sort processes in the CPU display.

prevents surprising effects post-installation on serial-only x86 systems
(e.g. bhyve) where the kernel messages will appear, rc scripts will run,
and then there will be no login prompt and you will be locked out of the
system.
Thanks to Devin Teske and Peter Grehan for ideas and testing. With this
patch, it may also be possible to unify all or most of the machine-specific
ttys files.
- Make the USB boot library more configurable.
- Resolve compile issues when cross building.
- Allow use of separate malloc.
- Allow use of separate endian macros.

o Allow setting keymap in FDT, use hardcoded one by default
o Represent fallback keymap as a list rather than directly usable M*N array

Add kernel config and FDT file for RR Lite board.

If a vt(4) font does not exactly fit the screen dimensions, the console
window is offset so that it is centered. A rectangle is drawn at the
top, left, right, and bottom of the screen, to erase any leftovers that
are outside of the new usable console area.
If the x offset or y offset is 0 then the left border or top border
respectively is not drawn. The right and bottom borders may be one
pixel larger than necessary due to rounding, and are always drawn.
Prior to this change a 0 offset would result in a panic when calling
vt_drawrect with an x or y coordinate of -1.

vt_grow may be called with a new size that's larger than previous but
does not require reallocation - for example, when the number of columns
is the same and new number of rows is less than the history size.
Prior to this change we would fail to update vb_scr_size, and then hit
a KASSERT when trying to write to the newly visible rows.

ifa_ifwithnet() and ifa_ifwithdstaddr() The legacy functions will call the

Add legacy-compatible functions as described above. Ensure legacy
behavior when RT_ALL_FIBS is passed as fibnum.
sys/netinet/in_pcb.c

Call with _fib() functions if we must use a specific fib, or the
legacy functions otherwise.

Improve the udp_dontroute test. The bug that this test exercises is
that ifa_ifwithnet() will return the wrong address, if multiple
interfaces have addresses on the same subnet but with different
fibs. The previous version of the test only considered one possible
failure mode: that ifa_ifwithnet_fib() might fail to find any
suitable address at all. The new version also checks whether
ifa_ifwithnet_fib() finds the correct address by checking where the
ARP request goes.

(XScale mainly) expects the memory located before the kernel to be mapped,
and use it to allocate the page tables, the various stacks, etc.
A better fix would probably be to rewrite the various bla_machdep.c to stop
using that RAM, but I'm not so inclined to do it, especially since I don't
have hardware for all of them.
correctly prepare KGSBASE msr to restore the user descriptor base on
the last swapgs during return to usermode.
