asm-generic: siginfo: define ia64 si_codes unconditionally
Unlike system call numbers the assignment of si_codes has never had a reason to be made per architecture. Some architectures have had unique conditions to report and reporting those conditions needed new si_codes. Nothing has ever needed si_codes to have different values on different architectures. The si_code space is vast so even with defining all si_codes on all architectures there is no danger in running out of si_code values. The history of the si_codes BUS_MCEERR_AR, BUS_MCEER_AO, SEGV_BNDERR, and SEGV_PKUERR show that a need of one architecture frequently becomes a need of another architecture which makes sharing si_codes between architectures a positive benefit and something to be encouraged. Where there are no conflicts with the historical ia64 arch specific si_codes and any other si_codes make them generic si_codes. We might need them on another architecture someday. This leaves only the good example of arch generic si_codes in the kernel for future architectures and architecture enhancments to follow. Without bad examples to follow it should be easy to avoid the mistakes of the past. Reported-by: Eric W.
