    sys/kern             sysv_shm.c 
    sys/sys              shm.h 
    usr.bin/ipcs         ipcs.c 
  Change the data type of the upper shared memory limits from a signed
  integer to an unsigned long. This lifts variables like the maximum
  number of pages available for shared memory from 2^31 to 2^32 on 32
  bit architectures, and from 2^31 to 2^64 on 64 bit architectures.
  It should be noted that this changes breaks ABI on 64 bit architectures
  because the size of the shmmax, shmmin, shmmni, shmseg and shmall members
  of the shminfo structure has changed.
