Hi Ben,

Today's linux-next build (powerpc ppc64_defconfig) produced this warning:

arch/powerpc/platforms/Kconfig.cputype:60:warning: defaults for choice values not supported

We appear to have CONFIG_PPC_BOOK3S int two places which is confusing
Kconfig.

Yes, I see that. One place depends on PPC32 and the other one PPC64, but
it still seems to be somewhat confused. In any case, it seems to still
do the right thing, so not a big hurry here, but I'll do a patch that
does it differently.

Cheers,
Ben.

Hi all,

Today's linux-next build (powerpc ppc64_defconfig) produced this warning:

kernel/time/tick-sched.c: In function 'tick_nohz_stop_sched_tick':
kernel/time/tick-sched.c:261: warning: format '%02x' expects type 'unsigned int', but argument 2 has type 'long unsigned int'

Introduced by commit 6826a57d1abc8ac9f59b24f1a008554c6560a995 ("powerpc:
Switch to asm-generic/hardirq.h") which changed
irq_cpustat_t::__softirq_pending from "unsigned int" to "unsigned long"
on powerpc.

Hah, that's an interesting one.  In currently mainline the following
architectures have it as unsigned long:

	alpha, parisc and blackfin/microblaze via asm-generic

and all others have it as unsigned int.  For blackfin and microblaze
it obviously doesn't matter, so the question is why alpha and parisc
have it as usinged long.  We defintively should standardize on one,
and unless alpha and parisc have good reasons for needing a long
value that would be unsigned int.
