From: Jens Freimann <jf...@linux.vnet.ibm.com>
Currently we use a mixture of atomic/non-atomic bitops
and the local_int spin lock to protect the pending_irqs bitmap
and interrupt payload data.
We need to use atomic bitops for the pending_irqs bitmap everywhere
and in addition acquire the local_int lock where interrupt data needs
to be protected.
