From: Claudio Imbrenda <imbrenda@xxxxxxxxxxxxx> gmap.h references radix trees, but does not include linux/radix-tree.h itself. Sources that include gmap.h but not also radix-tree.h will therefore fail to compile. This simple patch adds the include for linux/radix-tree.h in gmap.h so that users of gmap.h will be able to compile.
