lib: Export interval_tree
lib/interval_tree.c provides a simple interface for an interval-tree (an augmented red-black tree) but is only built when testing the generic macros for building interval-trees. For drivers with modest needs, export the simple interval-tree library as is. v2: Lots of help from Michel Lespinasse to only compile the code as required: - make INTERVAL_TREE a config option - make INTERVAL_TREE_TEST select the library functions and sanitize the filenames & Makefile - prepare interval_tree for being built as a module if required Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Michel Lespinasse <walken@google.com> Cc: Rik van Riel <riel@redhat.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Andrea Arcangeli <aarcange@redhat.com> Cc: David Woodhouse <dwmw2@infradead.org> Cc: Andrew Morton <akpm@linux-foundation.org> Reviewed-by: Michel Lespinasse <walken@google.com> [Acked for inclusion via drm/i915 by Andrew Morton.] [danvet: switch to _GPL as per the mailing list discussion.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
