Space allocated by 'union __vfp' is too small and cannot hold full VFP context. - move structures defined in fp.h to more appropriate headers. - remove all unused VFP structures. r315973: Save VFP state on fork(). Update the copy of VFP state in PCB before it is cloned for new process. r315974: Preserve VFP state across signal delivery. END
