The hrtimer mode of broadcast queues hrtimers in the idle entry
path so as to wakeup cpus in deep idle states. hrtimer_{start/cancel}
functions call into tracing which uses RCU. But it is not legal to call
into RCU in cpuidle because it is one of the quiescent states. Hence

The patch removes unused file eeh-ioda.c and updates makefile
accordingly. Besides, the definition of "struct pnv_eeh_ops" and
the instances are all removed. Until now, the chip layer of EEH
implementation for PowerNV platform is removed completely.

The EEH was implemented for PowerNV platform with 2 layers, which are
supported by "struct eeh_ops" and "struct pnv_eeh_ops" separately. The
latter, called chip layer, was introduced for EEH guest support initially.
However, the EEH guest support was implemented depending on "struct eeh_ops"

sysfs_create_groups() creates groups one by one in the attr_groups array
before a NULL entry is encountered. But if an error is seen, it stops
and removes all the groups already created:
