Fix the incorrect use of igrab() inside the i_lock in NFS and Ceph‥

If we are already holding the i_lock, we have a reference to the
inode so we can safely use ihold() to gain an extra reference. This

powerpc: cell: Fix the irq_desc access

The core irq_set_type() function updates the flow type when the chip

irq_ack() to check for the level bit. That avoids a redundant sparse
