  Modified files:
    sys/kern             sysv_shm.c 
  Log:
  shmat: If VM_PROT_READ_IS_EXEC is defined and prot includes VM_PROT_READ,
  VM_PROT_EXECUTE must be added to prot before calling vm_map_find.
  
  Without this change, an mprotect on a shmat'ed region fails (when
  it shouldn't).  This bug was reported Feb 28 by Brooks Davis
  <brooks@one-eyed-alien.net> on -hackers.
