We found these warnings in arch/powerpc/kernel/time.c as follows:
warning: symbol 'decrementer_max' was not declared. Should it be static?
warning: symbol 'rtc_lock' was not declared. Should it be static?
warning: symbol 'dtl_consumer' was not declared. Should it be static?

Declare 'decrementer_max' in powerpc asm/time.h.
Include linux/mc146818rtc.h in powerpc kernel/time.c where 'rtc_lock'
is declared. And remove duplicated declaration of 'rtc_lock' in powerpc
platforms/chrp/time.c because it has included linux/mc146818rtc.h.
Move 'dtl_consumer' definition behind "include <asm/dtl.h>" because it
is declared there.

V2:
- Instead of including linux/mc146818rtc.h in powerpc kernel/time.c, declare
  rtc_lock in powerpc asm/time.h.
V3:
- Recover to V1, that is including linux/mc146818rtc.h in powerpc
  kernel/time.c. And remove duplicated declaration of 'rtc_lock' in powerpc
  platforms/chrp/time.c because it has included linux/mc146818rtc.h.

I'm fine with that but I really think my suggestion to make the rtc_lock
local to the platforms was better because it is only used to synchronize
between concurrent invocations of chrp_set_rtc_time or
maple_set_rtc_time. The rtc core will never do that and the only case
would be concurrent calls to rtc_ops.set_time and
update_persistent_clock64 (which should also be removed at some point).

I agree but I think it must be done carefully. If the lock is local to the driver really and without 
a link with the RTC core, then the lock var should probably be static. But then we'll have name 
conflict with the global rtc_lock which is declared in <linux/mc146818rtc.h>

All this is not easy, and I like your idea in the other mail to really clean up the rtc core and 
remove this global rtc_lock completely.

For the time being I guess the fix provided by this patch is just semantic and is just fine as is, 
as there is no real bug behind the messages from sparse.

Many thanks for your suggestion. As you suggest, rtc_lock should be 
local to platforms.

Does it mean not only powerpc but also all other platforms should adapt 
this change?

It might be a big change. I have no idea if that's OK. What are other 
maintainers' opinions?


Thanks.
