Hi,
Today's mainline build, breaks on Power6 and Power7 (all BE config) with
these build errors
arch/powerpc/kernel/time.c: In function ‘running_clock’:
arch/powerpc/kernel/time.c:712:2: error: implicit declaration of
function ‘cputime_to_nsecs’ [-Werror=implicit-function-declaration]
return local_clock() -
cputime_to_nsecs(kcpustat_this_cpu->cpustat[CPUTIME_STEAL]);
^
cc1: some warnings being treated as errors
make[1]: *** [arch/powerpc/kernel/time.o] Error 1

What exact config is that?
And what compiler are you using?
I build ~250 configs with two different compilers multiple times a day,
so I'm curious how we failed to notice this.
cheers

Hi Abdul,
Are there any extra patches in your tree? I briefly tried to reproduce
this, but in my local tree this line:
return local_clock() - cputime_to_nsecs(kcpustat_this_cpu->cpustat[CPUTIM=
E_STEAL]);
Is at time.c:692 rather than time.c:712

Hi Abdul,
Are there any extra patches in your tree? I briefly tried to reproduce
this, but in my local tree this line:
I think the failure reported here is against linux-next tree.
Abdul can you confirm ?
With today’s linux-next tree I can recreate this build failure
CC arch/powerpc/kernel/sysfs.o
CC arch/powerpc/kernel/cacheinfo.o

This is with big endian config. I have attached the config file.
The system has gcc version 4.8.5
Thanks

Thanks for reporting this!
I just sent a fix.
