Please stick to imperative tone. For example (feel free to improve):
	struct msr_param contains pointers to both struct rdt_resource
	and struct rdt_domain, thus only struct msr_param is necessary.

	Pass struct msr_param as a single parameter. Clean
	up formatting and fix some fir tree declaration ordering.

The patch looks good to me, thank you.
