      * Report the RSDP to the kernel. While this can be found with
      * a BIOS boot, the RSDP may be elsewhere when booted from UEFI.
-     * The old code used the 'hints' method to communite this to
-     * the kernel. However, while convenient, the 'hints' method
-     * is fragile and does not work when static hints are compiled
-     * into the kernel. Instead, move to setting different tunables
-     * that start with acpi. The old 'hints' can be removed before
-     * we branch for FreeBSD 12.
