Subject: [PATCH 00/17] -Wmissing-prototype warning fixes

From: Arnd Bergmann <[email protected]>

Most of the patches I sent so far for the -Wmissing-prototype warnings
have made it into linux-next now. There are a few that I'm resending
now as nobody has picked them up, and then a number of fixes that I
found while test-building across all architectures rather than just the
ones I usually test.

The first 15 patches in this series should be uncontroversial, so
I expect that either a subsystem maintainer or Andrew Morton can
apply these directly.

For the last two patches, these might still need some debate about how
to handle them. I added a Kconfig option to turn off most of the missing
prototype warnings in the architectures that nobody has fixed yet,
see patch 16 for those. The last patch does cause some known warnings
and likely unknown ones for architectures other than x86 and arm,
so applying it now will bring new problems, but not applying it also
means that new warnings creep in, so I think this is mainly a question
of what the best timing is for having this in linux-next.

Subject: [PATCH 16/17] [RFC] arch: turn -Wmissing-prototypes off conditionally

From: Arnd Bergmann <[email protected]>

I have cleaned up the -Wmissing-prototypes warnings for most of the major architectures
as well as all drivers that get enabled for CONFIG_COMPILE_TEST, so now these should be
close to fixed on x86, arm, arm64, powerpc, s390, and riscv.

The other architectures tend to have a lot of these warning in architecture specific
code, primarily from functions that are only called from assembler code and do
not otherwise need a declaration but still cause a warning without one. Other cases
are simply functions that should just be static or are missing an #include statement.

In order to be able to turn the warning on globally by default without breaking all
these architectures, add a list of exceptions for architecture directories that
can revert back to the old behavior of not warning based on a new
CONFIG_WNO_MISSING_PROTOTYPES option.

do not need to be part of the changelog.

Subject: [PATCH 02/17] [RESEND] irq_work: consolidate arch_irq_work_raise prototypes

From: Arnd Bergmann <[email protected]>

The prototype was hidden on x86, which causes a warning:

kernel/irq_work.c:72:13: error: no previous prototype for 'arch_irq_work_raise' [-Werror=missing-prototypes]

Fix this by providing it in only one place that is always visible.

Subject: [PATCH 14/17] kprobes: unify kprobes_exceptions_nofify() prototypes

From: Arnd Bergmann <[email protected]>

Most architectures that support kprobes declare this function in their
own asm/kprobes.h header and provide an override, but some are missing
the prototype, which causes a warning for the __weak stub implementation:

kernel/kprobes.c:1865:12: error: no previous prototype for 'kprobe_exceptions_notify' [-Werror=missing-prototypes]
1865 | int __weak kprobe_exceptions_notify(struct notifier_block *self,

Move the prototype into linux/kprobes.h so it is visible to all
the definitions.

Subject: [PATCH 15/17] arch: fix asm-offsets.c building with -Wmissing-prototypes

From: Arnd Bergmann <[email protected]>

When -Wmissing-prototypes is enabled, the some asm-offsets.c files fail
to build, even when this warning is disabled in the Makefile for normal
files:

arch/sparc/kernel/asm-offsets.c:22:5: error: no previous prototype for 'sparc32_foo' [-Werror=missing-prototypes]
arch/sparc/kernel/asm-offsets.c:48:5: error: no previous prototype for 'foo' [-Werror=missing-prototypes]

Address this by making use of the same trick we have on other architectures,
renaming the unused global function to main(), which has an implicit
prototype.

On loongarch, there are many functions in this file, so the trick does
not work, adding explicit declarations works around it in a slightly
more ugly way but is the best I could come up with here.

Subject: [PATCH 11/17] scsi: gvp11: remove unused gvp11_setup() function

From: Arnd Bergmann <[email protected]>

This function has no declaration, which causes a warning:

drivers/scsi/gvp11.c:53:6: error: no previous prototype for 'gvp11_setup' [-Werror=missing-prototypes]

Since there is also no caller, just remove the function.

Some architectures only have a few of those errors/warnings.

For instance microblaze and parisc only have one each. Isn't it better
to fix them rather then turn the errors off ?

Others like loongarch which is a recent actively maintained
architecture, I'd expect the 30 errors to be easy to fix.

Many of the alpha ones seems to be brought by your commit e19d4ebc536d
("alpha: add full ioread64/iowrite64 implementation")

Arnd, I like your patch!
For parisc I've done quite some work during the last few weeks to
get such warnings sqeezed out, so please drop the hunk for parisc from
your patch. My plan is to become warning-free before 6.5-final.

This last one:
arch/parisc/lib/ucmpdi2.c:12:5: error: no previous prototype for '__ucmpdi2' [-Werror=missing-prototypes]
I'll take care in the parisc for-next tree.

Thanks!

The list was only the 'defconfig' warnings, there are a couple more
that I saw with 'allmodconfig', and I'm sure there are even more
when dealing with other random configurations.

I did send other fixes for microblaze and parisc specific drivers,
and I could also send patches for the two defconfig warnings if
the maintainers are happy with fixing those but leaving allmodconfig
to still warn, but I feel that it's easier for them to just
do the last fixes themselves and then remove my hack again.

I'll wait for Michal and Helge on these.

Agreed, they probably are.

As far as I can see, those already existing before that patch, though
I did touch the same lines there.

In the end it's a matter of where to stop, as there are endless
configurations to test if I want to do a complete job. I drew the
line between powerpc (which I tried to fix) and mips (which I left
alone), mainly because the powerpc side was already exhausting
and mips has even more obscure configurations. The other ones on
the list are all less actively maintained than these two.

Likewise, I'll clean up ARC errors this weekend !
It seems most of therm are in the category you mentioned. Non static but

I'll try to get these fixed for 6.6. I was looking at them recently but did not
actually make any changes and just put on my TODO. Your series moves it up in
priority and it should be easy to get the fixes out.

What do you mean by "hidden on x86"?

arch_irq_work_raise() was declared on 7 architectures,
including x86.

main() only works for one function call, but
there are some cases where splitting the code
into some functions makes the code cleaner.

I do not like repeating the function names.

Could you try "static + __used" as in
arch/x86/kernel/asm-offsets.c ?

I meant hidden in some configurations. Specifically, x86
only declares the function when it overrides it for
CONFIG_X86_LOCAL_APIC, while without that option the generic
stub still gets compiled but is never declared.

Right, I went with main() as that is already used on a couple
of architectures.

Sure, that should work, I had not noticed x86 doing it like this
and I agree it's slightly nicer.

In this case, Thomas Bogendoerfer already merged my patch for MIPS
in 6.5. The loongarch file I change here is a copy of the same file,
so we probably want them to stay consistent, either keeping my
change for now, or reworking mips along the same lines.

Thanks!

Since we already have the majority of architecture maintainers stepping
in to fix the warnings, I wonder if I should just drop my patch 16/17
completely and let the others handle it as well rather than shutting up
the warnings. Only the asm-offsets change is really needed to compile
test most of the kernel even with CONFIG_WERROR, and without that this
is just some harmless output.
