Since SDCIAE is the architecture specific feature while the generic resctrl feature
is "io_alloc" I think it will be more accurate to say something similar to the
ABMC changelog:
	Add a kernel command-line parameter to enable or disable the exposure of
	the L3 Smart Data Cache Injection Allocation Enforcement (SDCIAE) hardware
	feature to resctrl.
