This got me to thinking there may be other header files that are
potentially not used in rtems.git, and of questionable value to keep
there:

cpukit/include/rtems/vmeintr.h
cpukit/include/rtems/spurious.h
cpukit/include/rtems/score/smplockseq.h
cpukit/include/rtems/score/smplockmcs.h
cpukit/include/rtems/rtemsdialer.h
cpukit/include/rtems/mptables.h

Anyone have insight on whether these headers are unused, or are used
in other dependent repos and should be considered for migration?
