  SVN rev 189740 on 2009-03-12 13:45:55Z by kib
  
  MFC r189283:
  Correct types of variables used to track amount of allocated SysV shared
  memory from int to size_t. Implement a workaround for current ABI not
  allowing to properly save size for and report more then 2GB sized segment
  of shared memory.
  
  This makes it possible to use > 2 GB shared memory segments on 64bit
  architectures. Please note the new BUGS section in shmctl(2) and
  UPDATING note for limitations of this temporal solution.
  
  MFC r189398:
  Systematically use vm_size_t to specify the size of the segment for VM KPI.
  Do not overload the local variable size in kern_shmat() due to vm_size_t
  change.
  Fix style bug by adding explicit comparision with 0.
  
  MFC r189399:
  Improve the grammar and wording in the changes to shmctl(2) manpage.
  
  Put an UPDATING entry and bump __FreeBSD_version for the change.
