All architecturally defined bits in the FPU implementation register are read only & unchanging. It contains some implementation-defined bits but the architecture manual states "This bits are explicitly not intended to be used for mode control functions" which seems to provide justification for viewing the register as a whole as unchanging. This being the case we can simply re-use the value we read at boot rather than having to re-read it later, and avoid the complexity which that read entails.
