Having si_codes in many different files simply encourages duplicate definitions that can cause problems later. To avoid that merge the blackfin specific si_codes into uapi/asm-generic/siginfo.h Update copy_siginfo_to_user to copy with the absence of BUS_MCEERR_AR that blackfin defines to be something else.
