Extend WARN_ON and BUG_ON style output from:

  WARNING: CPU: 0 PID: 0 at kernel/sched/core.c:8511 sched_init+0x20/0x410

to:

  WARNING: CPU: 0 PID: 0 at [idx < 0 && ptr] kernel/sched/core.c:8511 sched_init+0x20/0x410

Note that the output will be further reorganized later in this series.

You say that, but I don't see that in the actual email, which only
went to lkml...

So the sh maintainers (and riscv and s390 etc: same issue with those
emails) probably never saw this.

The patches look fine to me, fwiw.

So I've changed the series slightly to add a new Kconfig option to 
trigger these extra strings:

	CONFIG_DEBUG_BUGVERBOSE_DETAILED=y

Disabled by default.

This should address concerns over the +100K kernel size increase that 
some have raised.

I'll send out a -v2 series, which should have the Cc: problems fixed as 
well, so that all architecture people see it too.

Thanks,

	Ingo

Indeed, usually I rely on the tip-bot picking up Cc: lines, but here it 
would be useful to have earlier Cc:s and my script had, for some stupid 
reason:

  --suppress-cc=all

... which certainly suppressed the Cc: lines :-/

Will take a careful look at a --dry-run output next time around and 
make sure the --signed-off-by-cc auto-cc logic picks up all the Cc: 
lines in the individual commits.

Yeah, will iterate it once more just to make sure.

Thanks,
