This looks like yet another stray variable not used anywhere including
core ACPI
It will be used by ACPICA to get the RSDP in acpi_tb_parse_root_table()
in tbutils.c.
No I couldn't find it in mainline/acpica/linux-next(pm tree).
On further digging found that commit fab461058385("ACPICA: Cleanup the
option of forcing the use of the RSDT") has renamed it to
acpi_gbl_do_not_use_xsdt and moved it into acpica with default false.
So you can remove this.
