The m32r architecture was the only user of the old-style rtc driver for ds1302. The architecture is getting removed now, and we have a modern driver for the same hardware in drivers/rtc/rtc-ds1302.c, so this one won't be missed. Acked-by:

The tile architecture is obsolete and getting removed. From all I can tell, later ARM based products use a different ethernet driver, so we should remove this one as well. Signed-off-by: -

The Tile architecture is obsolete and getting removed from the kernel, this driver appears to only be used there, and not on the ARM based successors (Tile-Mx, BlueField), so we should remove it as well. Acked-by:

A number of architecture ports are obsolete and getting dropped, so we no longer want to track the respective features. We already removed the lines for metag and mn10300, this does 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. Signed-off-by: -

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:

The frv, tile and blackfin architectures are being removed, so we can clean up this header by removing all the special cases except those for ia64. The SEGV_BNDERR and BUS_MCEERR_AR si_code macros are now defined unconditionally on all remaining architectures. Acked-by:

Tile was the only remaining architecture to implement alloc_remap(), and since that is being removed, there is no point in keeping this function. Removing all callers simplifies the mem_map handling. Reviewed-by:

The CONFIG_MPU option was only defined on blackfin, and that architecture is now being removed, so the respective code can be simplified. A lot of other microcontrollers have an MPU, but I suspect that if we want to bring that support back, we'd do it differently anyway. Signed-off-by: -

Hardwall is a tile specific feature, and with the removal of the tile architecture, this has become dead code, so let's remove it. Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: -

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! Signed-off-by:

The Tile architecture port was added by Chris Metcalf in 2010, and maintained until early 2018 when he orphaned it due to his departure from Mellanox, and nobody else stepped up to maintain it. The product line is still around in the form of the BlueField SoC, but no longer uses the Tile architecture. There are also still products for sale with Tile-GX SoCs, notably the Mikrotik CCR router family. The products all use old (linux-3.3) kernels with lots of patches and won't be upgraded by their manufacturers. There have been efforts to port both OpenWRT and Debian to these, but both projects have stalled and are very unlikely to be continued in the future. Given that we are reasonably sure that nobody is still using the port with an upstream kernel any more, it seems better to remove it now while the port is in a good shape than to let it bitrot for a few years first.
