  To: linux-sh; +Cc: ysato, dalias, linux-kernel, viro, Arnd Bergmann

sh5 never became a product and has probably never really worked.

Remove it by recursively deleting all associated Kconfig options
and all corresponding files.

For review purposes, this leaves out the files that can now be
removed, in particular

 arch/sh/drivers/pci/*-sh5.c
 arch/sh/include/asm/*_64.h
 arch/sh/include/uapi/asm/*_64.h
 arch/sh/include/cpu-sh5/*
 arch/sh/kernel/cpu/sh5/*
 arch/sh/lib64/*
 arch/sh/mm/*-sh5.c

From: Arnd Bergmann @ 2020-04-20 12:38 UTC (permalink / raw)
  To: linux-sh; +Cc: ysato, dalias, linux-kernel, viro, Arnd Bergmann

None of these files are used now that sh5 has been
disabled, so they can be completely removed.

Why keep the SUPERH32 symbol?
Because you forgot to clean a few files?

You might remove the empty definition, too, as you removed the sole user...

I think at least some of the following should be cleant, too:

And you forgot to remove the tlbex_64 stuff from arch/sh/mm/Makefile.

The following can be removed, too:

    arch/sh/mm/extable_64.c

And all the remaining BITS stuff:

Thanks, added this to the patch now, along with the corresponding
Makefile changes I missed as well. I left the definition of $(BITS)
in the Makefile, but removed all uses of it.

It seemed simpler this way, but I can remove it as well.

Ah, I had removed these at first when I renamed the *_32.h over
those files, but then decided to not do that, to keep the patch
easier to review.

Right, I planned to remove that one and forgot.

Thank you! I haven't reviewed this yet, but if others do before I get
to it I'm happy to go with their opinions. I've been wanting to get
this removed for a long time because cleaning out stuff that's not
used/useful makes it easier to see what needs to be done for sh2/3/4
(rest of DT conversion, mmu support for j-core).
