* 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.
