For UEFI systems: the UEFI loader(8), loader.efi, should be updated in

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
