1. A method of facilitating processing within a computing environment, said method comprising: obtaining, by a processor, an address translation mapping, wherein the address translation mapping comprises: a first address to be translated to a second address, the first address being of a first type and the second address being of a second type, the second address of the second type indicating a memory location that includes modified code of an application, the modified code accessible via an instruction fetch of the application; the first address to be translated to a third address, the third address being of the second type and indicating a memory location that includes unmodified code corresponding to the modified code, the unmodified code accessible via data accesses of the application; and a fourth address to be translated to the second address, the fourth address being of the first type, and wherein the modified code located at the memory location indicated by the second address is accessible via a data access by a component different from the application; and accessing the memory location indicated by the second address by at least one of the application using an instruction fetch or the component using a data access, the accessing including using the address translation mapping.
