    sys/sys              ipc.h shm.h 
    sys/kern             sysv_shm.c 
  Log:
  Make sure we restrict Linux only IPC calls from being executed
  through the FreeBSD ABI.  IPC_INFO, SHM_INFO, SHM_STAT were added
  specifically for Linux binary support.  They are not documented
  as being a part of the FreeBSD ABI, also, the structures necessary
  for them have been hidden away from the users for a long time.
  
  Also, the Linux ABI layer uses it's own structures to populate the
  responses back to the user to ensure that the ABI is consistent.
  
  I think there is a bit more separation work that needs to happen.
