Hi all,
this series moves various config options that are defined in multiple
arch Kconfig files into common files, usually close to the code
supporting such features.

__KERNEL__ is never not defined for non-uapi headers, and GENERIC_CSUM
isn't ever set for powerpc either.

HAVE_KPROBES is defined genericly in arch/Kconfig and architectures
should just select it if supported.

Introduce one central definition of RWSEM_XCHGADD_ALGORITHM and
RWSEM_GENERIC_SPINLOCK in kernel/Kconfig.locks and let architectures
select RWSEM_XCHGADD_ALGORITHM if they want it, otherwise default to
the spinlock version.

visible option - we introduce a xtensa-specific symbol instead to work
around this.

To: Masahiro Yamada
Cc: linux-kbuild, linuxppc-dev, linux-riscv, linux-s390,
linux-xtensa, linux-kernel
And just let the architectures that want it select the symbol.
Same for GENERIC_BUG_RELATIVE_POINTERS.

GENERIC_CSUM was abandonned by commit d4fde568a34a ("powerpc/64: Use
optimized checksum routines on little-endian")
Could you also remove the 'config GENERIC_CSUM' item in
arch/powerpc/Kconfig ?

This changes the behavior of nds32.
So please leave a note in the commit description.
(Ideally, we want Ack of a NDS32 maintainer)
Also, please do compile test for NDS32.
-------------------------
This commit changes CONFIG_LOCKDEP_SUPPORT to y for nds32.
NDS32 selects LOCKEP_SUPPORT, but there was previously
no config entry of LOCKDEP_SUPPORT in nds32.
It is now available in lib/Kconfig.debug,
so this commit enables LOCKDEP_SUPPORT for nds32.
-------------------------

This does not work because NO_IOMEM is defined
in arch/um/Kconfig.
If you want to do this,
you must move NO_IOMEM to lib/Kconfig.

This is a behavior change of nios2.
TRACE_IRQFLAGS_SUPPORT was previously 'n',
and this commit is changing it to 'y'.
Strangely, nios2 defines TRACE_IRQFLAGS_SUPPORT twice
with different default values.
In Kconfig, the first one becomes effective.
In this case, 'def_bool n' in arch/nios2/Kconfig is used.
'def_bool y' in arch/nios2/Kconfig.debug is dead code.
I think this select should be dropped
to keep the current behavior,
but I hope the NIOS2 maintainer will give us
some comments just in case.

Thank you to let us know this change.
I think it's ok to enable LOCKDEP_SUPPORT for nds32.
I just verified it in 5.0.0-rc1.

You missed to add 'select GENERIC_CSUM' for unicore32.

I saw, but the purpose of the later patch is to replace arch defined
GENERIC_CSUM by a common one that arches select. For the powerpc you are
not in that case as the powerpc does not select GENERIC_CSUM.
So I really believe that all stale bits of remaining GENERIC_CSUM in
powerpc should go away as a single dedicated patch, as a fix of commit
d4fde568a34a ("powerpc/64: Use optimized checksum routines on
little-endian")
Regarding the #ifdef __KERNEL__ , I think we should do a wide cleanup in
arch/powerpc/include/asm, not only asm/checksum.h

This slightly changes the behavior of GENERIC_BUG_RELATIVE_POINTERS
for arm64, riscv, x86.
Previously, GENERIC_BUG_RELATIVE_POINTERS was enabled only when BUG=y.
Having said that, this is not a big deal.
When CONFIG_GENERIC_BUG=n, CONFIG_GENERIC_BUG_RELATIVE_POINTERS
is actually don't care.
If you change this,
could you add some comments in commit description?

Hmm, s390 enables GENERIC_BUG_RELATIVE_POINTERS

Please send such cleanups to PowerPC ML
instead of to me (Kbuild).
Christoph,
I think this one is independent of the rest of this series.
How about separating it if you volunteer to Powerpc cleansup?

I think this is really confusing.
"ARCH has its own optimized hweight implementation"
is not equivalent to
"ARCH does not need generic hweight at all".
For example, see
arch/powerpc/lib/hweight_64.S
As far as I understood the code,
it will fallback to generic lib/hweight.c
if it turns out the optimized one is not available.
Thanks.
