   This files describes the CPU I/O 2 Protocol.\r
-  \r
+\r
   This protocol provides an I/O abstraction for a system processor. This protocol\r
   is used by a PCI root bridge I/O driver to perform memory-mapped I/O and I/O transactions.\r
   The I/O or memory primitives can be used by the consumer of the protocol to materialize\r
   bus-specific configuration cycles, such as the transitional configuration address and data\r
-  ports for PCI. Only drivers that require direct access to the entire system should use this \r
-  protocol. \r

+  ports for PCI. Only drivers that require direct access to the entire system should use this\r
+  protocol.\r
+\r
   Note: This is a boot-services only protocol and it may not be used by runtime drivers after\r
   ExitBootServices(). It is different from the Framework CPU I/O Protocol, which is a runtime\r
   protocol and can be used by runtime drivers after ExitBootServices().\r
