Notes A module can claim this vector if it wants to take over ownership of the FIQ vector. If the call is left unclaimed then the kernel will take ownership, installing a default handler which disables and ignores any received FIQ. This call should only be issued when a module voluntarily releases control of the FIQ vector. It should not be issued in response to [[Service_ClaimFIQ]] or [[Service_ClaimFIQinBackground]]. h4.
