Note: this isn't a general thing. It only affects u-boot-based arm64

systems. Make sure the note says that specific case only. Also,
provide a recipe to do it.

For UEFI systems: the UEFI loader(8), loader.efi, should be updated in
conjunction with installing a new kernel after r330868. The kernel,
after this revision, will be more lenient when mapping addresses for
UEFI Runtime Services and this may result in a kernel panic without the
corresponding loader(8) update.
For u-boot based arm64 UEFI systems: the UEFI loader(8), loader.efi,
should be updated in conjunction with installing a new kernel after
r330868. The kernel, after this revision, will be more lenient when
mapping addresses for UEFI Runtime Services and this may result in a
kernel panic without the corresponding loader(8) update. If you have a
recent kernel, you can do a installkernel / installworld and then reboot
as there's no recent syscall changes. If you have an older kernel and/or
a 11.x system, the following sequence is safe:
% make buildworld
% make buildkernel
% sudo make installkernel
% cd stand
% sudo make install
% sudo reboot

% sudo make installworld
