of the fp save area to all the process_read_fpregs() and process_write_fpregs() functions. None of the functions have been modified to use the new parameters. The size is set for all the writes, but some of the arch-specific reads just pass NULL. The amd64 (and i386) need variable sized fp register save areas in order to support AVX and other enhanced register areas. These functions are rarely called - so the extra argument won't matter.
