arch: remove unused *_segments() macros/functions
Some architectures define the no-op macros/functions copy_segments, release_segments and forget_segments. These are used nowhere in the tree, so removed them. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Acked-by: Vineet Gupta <vgupta@synopsys.com> [for arch/arc] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
