Hmmm... So you are building TINY_RCU without CONFIG_DEBUG_LOCK_ALLOC,
but with some checking enabled. I -thought- I was testing that...
But, wait. You do have CONFIG_DEBUG_LOCK_ALLOC defined. That really
should cause rcu_is_cpu_idle() to be compiled into kernel/rcupdate.o.
And your config builds on my system with no errors.
Was there perhaps another problem, maybe running out of disk space?
Thanx, Paul

I can reproduce the errors in a clean build. And I find the root cause to be
the below line in rcutiny.c:
=> #ifdef CONFIG_PROVE_RCU
/*
* Test whether RCU thinks that the current CPU is idle.
*/
int rcu_is_cpu_idle(void)
> Was there perhaps another problem, maybe running out of disk space?
Sometimes it does run out of *memory*, because I aggressively put all
.o files in tmpfs ;) In which case the make/gcc tasks are killed and
the abnormal situation is detected by grepping for "Terminated" lines
in the build log.
Thanks,

Ah! Fixed by d7118175 in -next, -tip, and -rcu. The bug was introduced
by 9b2e4f1880 in v3.3, but apparently the commit you found was the one
that actually exposed the bug.
What error were you bisecting for?

I don't know that the wfg@linux.intel.com email address works.
I added it it in the last thread an Fengguang said it only failed
because of a fluke. I insisted that it still wasn't working. But
I see now that Fengguang removed the working email address from
the list so my reply never got through.
Fengguang please leave your working email address on the CC list.

dan carpenter

It's probably a different error..
When you say "builds on my system w/o errors", you are talking about
the git head of this branch? That's true: the bug is introduced in
commit 62fde6e and then fixed by d711817:

The bad commit 62fde6e is actually committed on Jul 2, so it obviously
presents some new work:

Sorry, I didn't notice that. It seems that mutt automatically removes
my @intel.com address from the CC list, when the other
@linux.intel.com address is used..

Got it and replied :)

Check the patch. The bug was introduced by 9b2e4f1880, which used
CONFIG_PROVE_RCU rather than the correct CONFIG_DEBUG_LOCK_ALLOC.
Commit 62fde6e exposed the bug.
