Hi Dave, Control registers 8-15 (s390x and s390) and floating point registers 8-15 (s390x only) are not printed correctly because the we copy the content from the wrong location of the save area. Looks like nobody has realized this problem in the past because those registers are not too important for debugging kernel problems... This patch fixes this problem and now control and floating point registers are printed correctly.
