Dave,

Thanks for checking this out on x86, and getting it reverted.

Following up on this from yesterday, Linus please revert the above cset.
It doesn't seem to be necessary (it was added to fix a miscompile in
'make allnoconfig' which doesn't seem to be repeatable with it reverted)
and actively breaks the ARM SA1100 framebuffer driver.

(If you'd prefer a patch reverting it, I'll send one, but I'm

No.  That code is required - the StrongARM 1100 framebuffer driver
*needs* to know what the CPU frequency is so it can set the pixel clock
divisor.

The real problem is the silly people who added this to cpufreq.h:

#ifdef CONFIG_CPU_FREQ
unsigned int cpufreq_quick_get(unsigned int cpu); unsigned int
cpufreq_get(unsigned int cpu); #else static inline unsigned int
cpufreq_quick_get(unsigned int cpu) {
return 0;
}
static inline unsigned int cpufreq_get(unsigned int cpu) {
return 0;
}
#endif

which utterly bogus.

heh.

I think just reverting that change for .23 makes sense. It doesn't
seem that anything breaks by not having it there, and we know it
definitly breaks arm at least.

Could be that this patch fixed version 17 of sched-clock-share and we ended

Nothing breaks for me with make ARCH=i386 bzImage on my x86-64 box
(which should be the same as a native build).

The functions that complain in that patch header don't seem to actually
exist in mainline at all. (`init_sched_clock' and `call_r_s_f')
Did this patch perhaps jump the gun, and these are -mm only ?

OK, here: 
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.21-rc5/2.6.21-rc5-mm3/broken-out/fix-x86_64-mm-sched-clock-share.patch

So I guess what we want to do here is to revert that patch, test i386
allnoconfig and then fix up anything which breaks.

Oh geeze.  sched-clock-share went through about 18 different versions, was

I don't remember seeing any problem here, so I'm not entirely sure what

"Fix for the following patch" is also something that really should
never be added to a git changelog too, because 'next' means absolutely

No.  That code is required - the StrongARM 1100 framebuffer driver
*needs* to know what the CPU frequency is so it can set the pixel
clock divisor.

The real problem is the silly people who added this to cpufreq.h:

#ifdef CONFIG_CPU_FREQ
unsigned int cpufreq_quick_get(unsigned int cpu);
unsigned int cpufreq_get(unsigned int cpu);
#else
static inline unsigned int cpufreq_quick_get(unsigned int cpu)
{
return 0;
}
static inline unsigned int cpufreq_get(unsigned int cpu)
{
return 0;
}
#endif

which utterly bogus.

   I don't remember seeing any problem here, so I'm not entirely sure what
   this was supposed to be fixing.  Perhaps the -mm-esque patch name
   will provide Andrew/Andi clues. It lacks sufficient information for
   my brain to guess what the problem was.
  
  Oh geeze.  sched-clock-share went through about 18 different versions, was
  merged, unmerged, remerged, dropped, etc.  I don't recall at what stage in
  this mess the above fix was inserted, sorry.
  
   Fix for the following patch is also something that really should
   never be added to a git changelog too, because 'next' means absolutely
   nothing to me, nor I expect 99% of changelog readers.
  
  184c44d2049c4db7ef6ec65794546954da2c6a0e should never have existed,
  actually.  I intended that Andi fold it into the base patch prior to
  sending it to Linus.  He normally does that, but it looks like this
  one was handled as a standalone commit for some reason.

So lets see what happens if we revert it ?

So I guess what we want to do here is to revert that patch, test i386
allnoconfig and then fix up anything which breaks.

Nothing breaks for me with make ARCH=i386 bzImage on my x86-64 box
(which should be the same as a native build).

The functions that complain in that patch header don't seem to actually
exist in mainline at all. (`init_sched_clock' and `call_r_s_f')
Did this patch perhaps jump the gun, and these are -mm only ?

Could be that this patch fixed version 17 of sched-clock-share and we ended
up merging verion 56.  It was awful.

heh.

I think just reverting that change for .23 makes sense. It doesn't
seem that anything breaks by not having it there, and we know it
definitly breaks arm at least.

 I'm guessing no one ever ended up in the else section until now, and

 that the header was added some time ago and no one caught this.
 This patch worked for me to get rid of the compile time problems.  I'm

 having issues with the kernel, but as far as I can tell they are form 
 the Frame buffer and not because of this.  If this assessment is 
 correct {the not needing this code anymore} then please pass this 
 along so it makes it into an upcoming release.

No.  That code is required - the StrongARM 1100 framebuffer driver
*needs* to know what the CPU frequency is so it can set the pixel clock
divisor.

The real problem is the silly people who added this to cpufreq.h:

#ifdef CONFIG_CPU_FREQ
unsigned int cpufreq_quick_get(unsigned int cpu); unsigned int
cpufreq_get(unsigned int cpu); #else static inline unsigned int
cpufreq_quick_get(unsigned int cpu) {
return 0;
}
static inline unsigned int cpufreq_get(unsigned int cpu) {
return 0;
}
#endif

which utterly bogus.
