This patch aligns the logic used to check for the presence of adjacent segments in has_adjacent_segments() with the logic used in cleanup_segments() when actually deciding to concatenate or not a pair of segments. Additionally, adjacent segments are no longer considered overlapping to avoid generating errors for segments that can happily coexist together. This fixes an infinite loop that happened when segments where adjacent in their physical or virtual addresses but not in their ioremap addresses: has_adjacent_segments() reported the presence of adjacent segments while cleanup_segments() was not considering them for concatenation, resulting in an infinite loop since the result of has_adjacent_segments() is used in the decision to continue looping in cleanup_segments().
