the same edits for all the others.

The score architecture used a number of old system calls for compatibility
with a traditional libc port, all architectures that got added later
skip these. With score out of the way, we can finally clean up the
syscall list to no longer provide these.

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.

The CONFIG_MPU option was only defined on blackfin, and that architecture

The port was added back in 2000 so it's no longer even a good source
of inspiration for newer ports (if it ever was)

The last SoC (ARTPEC-3) with a CRIS main CPU was launched in 2008.

Coupled with time and working developer board hardware being
in low supply, it's time to drop the port from Linux.

So long and thanks for all the fish!
