From: Arnd Bergmann <arnd@arndb.de>

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.

Below is the full list of warnings I see in defconfig builds for reference, these
do not need to be part of the changelog.

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")

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.

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!
Helge

Thx, Arnd, I will clean them up for the csky part.

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.

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.
