See http://www.infradead.org/rpr.html Precedence: bulk List-ID: X-Mailing-List: linux-pm@vger.kernel.org Remove all unused defines, and just use the expanded versions for the SCSI disk majors. I've decided to keep Root_RAM0 even if it could be expanded as there is a lot of special casing for it in the init code.
