The address at which a function or task begins to execute. In C, the
entry point of a function is the function's name.
envelope
A buffer provided by the MPCI layer to RTEMS which is used to pass
messages between nodes in a multiprocessor system. It typically contains
routing information needed by the MPCI. The contents of an envelope are
referred to as a packet.

SMP locks
The SMP locks ensure mutual exclusion on the lowest level and are a
replacement for the sections of disabled interrupts. Interrupts are
usually disabled while holding an SMP lock. They are implemented using
atomic operations. Currently a ticket lock is used in RTEMS.
SMP barriers
The SMP barriers ensure that a defined set of independent threads of
execution on a set of processors reaches a common synchronization point
in time. They are implemented using atomic operations. Currently a
sense barrier is used in RTEMS.
