Changeset 84e6f15 in rtems for cpukit/score/cpu/epiphany/rtems

score: Robust thread dispatch

On SMP configurations, it is a fatal error to call blocking operating
system with interrupts disabled, since this prevents delivery of
inter-processor interrupts. This could lead to executing threads which
are not allowed to execute resulting in undefined behaviour.

The ARM Cortex-M port has a similar problem, since the interrupt state
is not a part of the thread context.

Update #2811.
