ACPI, APEI, EINJ, limit the range of einj_param
On the platforms with ACPI4.x support, parameter extension is not always doable, which means only parameter extension is enabled, einj_param can take effect. v2->v1: stopping early in einj_get_parameter_address for einj_param Signed-off-by: Chen Gong <gong.chen@linux.intel.com> Acked-by: Tony Luck <tony.luck@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
