I have a question regarding the EVA (spacewalk) by Michael Fossum and Ron Garan that took place during the STS-135 mission.

Is it considered a shuttle or ISS EVA?

The reason I ask is because neither EVA crew member was actually a part of the shuttle flight crew, and looking through my records ISS (U.S.) EVA #17 took place in August 2010 during Increment 24, and U.S. EVA #18 took place during Increment 32 in August 2012.

The spacewalk was considered an STS-135 EVA. From the mission's press kit:
The last spacewalk to be performed by space shuttle crew members took place on STS-134, but not the last spacewalk to be performed during a space shuttle mission.

Although STS-135 was not originally intended to include a spacewalk, the desire to return a pump module that failed on the International Space Station in 2010 to the Earth for analysis made one necessary, and over time other tasks were added to it as well. With only four people, however, the STS-135 crew was too small to perform a spacewalk on top of all of its other work. So members of the Expedition 28 crew were recruited for the job, though the shuttle crew members will still support the spacewalk from inside the space station.

Plus, the other thing to keep in mind is while Rex Walheim didn't go out the airlock door, he did hands on NBL training to refine the techniques for the EVA while the spacewalkers themselves were in final preparations for their launch on the Soyuz.

This recent NASA webpage has an ISS EVA graphic, and the spacewalk by Fossum and Garan on July 12, 2011 is listed as an Expedition 28 EVA.

Here is Walking to Olympus: An EVA Chronology, 1997–2011 Volume 2 by Julie B. Ta and Robert C. Treviño.
Following the first volume of "Walking to Olympus: An EVA Chronology," which recounted the period from the first spacewalks in 1965 to the end of the Shuttle-Mir program in 1997, this second volume of "Walking to Olympus" spans the period from 1997 to the end of the Space Shuttle Program in 2011.

It includes not only spacewalks performed by American and European astronauts and the Russian/Soviet cosmonauts, but also those of the newest members of the EVA community, the taikonauts of the People's Republic of China. Several key events and themes from this period include the building of the ISS, the servicing of the Hubble Space Telescope, and the STS-107 Columbia accident.

The publication of this second EVA chronology follows two major anniversaries of significance to the spaceflight community: the 50th anniversary of the first EVA and the 25th anniversary of the Hubble Space Telescope. The phrase "Walking to Olympus" is a symbolic expression of humans inevitably landing on Mars and exploring the planet, including Olympus Mons, the largest volcano in our solar system.

This sounds like one of those questions that can have different answers for what you consider a shuttle EVA? Is a shuttle EVA one that only uses the shuttle airlock or shuttle crew member, or while a shuttle was docked to ISS? STS-125 could be the last shuttle era EVA, since it was the last shuttle air lock EVA, or 135 since it was docked to the ISS.
