Warner Losh bd3bce41db Deprecate using hints.acpi.0.rsdp to communicate the RSDP to the ... system. This uses the hints mechnanism. This mostly works today because when there's no static hints (the default), this value can be fetched from the hint. When there is a static hints file, the hint passed from the boot loader to the kernel is ignored, but for the BIOS case we're able to find it anyway. However, with UEFI, the fallback doesn't work, so we get a panic instead. Switch to acpi.rsdp and use TUNABLE_ULONG_FETCH instead. Continue to generate the old values to allow for transitions. In addition, fall back to the old method if the new method isn't present. Add comments about all this. Differential Revision: https://reviews.freebsd.org/D5866		2016-04-14 04:59:51 +00:00
