The of_property_{read,count,match}_string* family of functions never
modify the struct device_node pointer that is passed in, so there is no

LNet is an abstraction built on top of network APIs such
as infiniband or TCP/IP layer. Since LNet is dependent
on these other layers we should ensure LNet headers
should always come after the infiniband header since the
infiniband headers can influence the LNet header
definitions.

The lock was an overkill, the same can be done with atomics.
A mb() was added in kvm_pit_ack_irq, to pair with implicit barrier
between pit_timer_fn and pit_do_work. The mb() prevents a race that
could happen if pending == 0 and irq_ack == 0:
