Changes from v2:

	* Remove usleep API
		It seemed the weak consensus that the best way to
		force callers to consider the cost / implications
		of the underlying hrtimers was to leave only the
		range API as an option. Given the dangers of an
		implicit slack coupled with the potential
		proliferation of interrupts with no slack, forcing
		callers to supply a range seems the best choice.

	* Documentation updated to reflect changes

	* Fix checkpatch warnings to point to the correct file
