Summary

Document why kexec_load() currently relies on PRIV_REBOOT for access
control, noting that loading a new kernel image is more powerful than
a traditional reboot and may warrant finer-grained privileges in the
future.

No functional change intended.

Test Plan

Not applicable (comment-only change).
