i thought you as a PowerPC person would be more suited to fix them than 
me.

but it took me 30 minutes - much less than the total time just i had to 
spend on similar issues in the past. So this patch will be a real 
time-saver and it should have been done years ago.

Tested on ppc64-defconfig - i guess there's more to it but similarly 
trivial.

Subject: powerpc: change u64/s64 to a long long integer type
From: Ingo Molnar <mingo@elte.hu>
Date: Mon Dec 22 08:32:41 CET 2008

Convert arch/powerpc/ over to long long based u64:

 -#ifdef __powerpc64__
 -# include <asm-generic/int-l64.h>
 -#else
 -# include <asm-generic/int-ll64.h>
 -#endif
 +#include <asm-generic/int-ll64.h>

This will avoid reoccuring spurious warnings in core kernel code that 
comes when people test on their own hardware. (i.e. x86 in ~98% of the 
cases) This is what x86 uses and it generally helps keep 64-bit code 
32-bit clean too.

I have missed the introduction.
Can you explain why?

I have done a bit of sparc hacking lately and was wondering if
sparc needs something similar.

This should only affect 64-bit architectures.

In the sparc-next tree:

ls arch/sparc64
ls: arch/sparc64: No such file or directory

We have unified sparc and sparc64 so they are in the same arch directory now.
This will hit mainline in the upcoming merge window.

This has happended over at the sparclinux mailing list as this was
sparc/sparc64 specific stuff so no wonder you have not heard about it.

People keep on doing

	printk("%llu", some_u64);

testing it only on x86_64 and this generates a warning storm on
powerpc, sparc64, etc.  Because they use `long', not `long long'.

And not just a little bit - this bug gets repeated maybe ten times per
week - it's insane.

If we make all architectures use `long long' then the above code
becomes correct and warning-free on all architectures.

And we then get to remove all the open-coded (unsigned long long) casts
which we added all over the tree (hundreds of them).

Yes, quite a few 64-bit architectures are using `long' for their
s64/u64 types.  We should convert them all to `long long'.

That's quite trivial to do, but it causes a lot of warnings due to code
in arch-speciic files which does

	printk("%lu", some_u64);

which will then generate a warning.  Or an error if the archtiecture
uses -Werror, which several do.  So we need to simultaneously convert
all those to %llu.  (Or %Lu, which saves a byte :))

    Quite a few 64-bit architectures are using `long' for their
    s64/u64 types.  We should convert them all to `long long'.

Update types.h so we use unsigned long long for u64 and
fix all warnings in sparc64 code.
Tested with an allnoconfig, defconfig and allmodconfig builds.

This patch introduces additional warnings in several drivers.
These will be dealt with in separate patches.

It may take a few days before the drivers gets fixed.

[PATCH] sparc64: fix unsigned long long warnings in drivers

[Sam Ravnborg]

Fix warnings caused by the unsigned long long usage in sparc
specific drivers.

The drivers were considered sparc specific more or less from the
filename alone.

Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
---

This turned out easier than expected.
There were a few generic related warnings that I did not touch.
I can split it up in smaller chunks if preferred.

wait, why does this need to be changed?


People having problem with:

        u64 data;
        seq_printf(m, "%llu ", data);

This compiles fine with arch that defines u64 to unsigned long long
(like x86), but generate compile time warning on arch that defines u64
to unsigned long.

Isn't that you just need to convert format string to %llu for u64 type?

We have:
        clocksource_tick.read = tick_ops->get_tick;

And clocksource_tick is of type clocksource:

struct clocksource {
	...
        cycle_t (*read)(void);

And cycle_t is:
/* clocksource cycle base type */
typedef u64 cycle_t;

And u64 is now:
unsigned long long - thus we need to fix prototype
of get_tick to fix the warnings.

A cast could do it - but fixing the real problem
is better here.

Sounds good to me.  It was just a question.  Thank you for the explanation.

Hey - it triggered me to take a deeper look at it.
And thanks for actually reading the patch - it's always good that
an extra pair of eyes look over it even it is only quick browsing.

Even with this and your driver patch applied, the tree
doesn't build successfully:

cc1: warnings being treated as errors
arch/sparc/kernel/psycho_common.c: In function ‘psycho_check_stc_error’:
arch/sparc/kernel/psycho_common.c:104: warning: format ‘%016lx’ expects type ‘long unsigned int’, but argument 4 has type ‘long long unsigned int’

Did you remove sparc's -Werror when doing test builds
of these changes? :-)

Either way these need some work before they should be
added to any tree.

Andrew you probably want to toss these from your tree
since at a minimum they will break the sparc64 build.

Sam will fix them up and resubmit, and I'll apply them,
don't worry. :)

No - it is worse than that.
My gcc does not complain about the above.

Just to check that I was not fouled by some preprocessor magic
here is the preprocessed code:

   printk("<3>" "%s: STC_TAG(%d)[PA(%016lx)VA(%08lx)"
          "V(%d)W(%d)]\n",
          pbm->name,
          i,
          ((tagval & 0x0fffffff00000000UL) >> 19UL),
          (tagval & 0x00000000ffffe000UL),
          ((tagval & 0x0000000000000002UL) ? 1 : 0),
          ((tagval & 0x0000000000000001UL) ? 1 : 0));


tagval is u64.

So it looks like my gcc does not promote:
((tagval & 0x0fffffff00000000UL) >> 19UL) to unsigned long long int
but your gcc does?

My gcc (build with Dan Kegel's crosstool):

I'm using a native gcc-4.1.3 here:

gcc (GCC) 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)

When you cross build 32-bit to 64-bit, a small but non-zero
number of warning checks and optimizations are not performed
and I think that is what you're hitting here.

OK.
I have ordered a used Sun Blade 100(*) that should show up
before new eve.
So when I have it and it is up and running I will redo this
patch set. That will likely take a few weeks though.

(*) Any distribution recommendations? I will only use it for
    sparc kernel development so nothing fancy...

Another option, of course, is to use 64-bit cross tools
on an x86_64 system if you have access to one of those.

Debian testing works fine, and that's what I'm typing this
on.

It needs a new motherboard and I used my savings on a Sun blade...

Thanks for this great start.  Just a few comments ...

Firstly, it would be nice if we could split this into things we can do
now (e.g. logical bug fixes) and things that must be done at the time of
the u64 type change (e.g. the printk's etc).  That will make the second
patch hopefully somewhat smaller.

These casts are actually not needed at all as of_get_flat_dt_prop()
returns "void *".

Wouldn't it make more sense to change the prototype to match the
implementation and the only caller (which passes an "unsigned long")?

in_be64()'s argument is "const volatile u64 __iomem *" so the
original "unsigned long" should have been "u64".

I have submitted a different patch for this.  The bitops work on unsigned
longs, so I changed the "flags" to be unsigned long.

So, would you like me to push this along - including splitting it up a
bit (keeping your Signed-off-by, of course)?

Sure, feel free - this should really be done by someone with more PowerPC 
interest/experience than me.
