Log:
  vm_page.c: include opt_msgbuf.h for MSGBUF_SIZE use in vm_page_startup
  
  vm_page_startup uses MSGBUF_SIZE value for adding msgbuf pages to minidump.
  If opt_msgbuf.h is not included and MSGBUF_SIZE is overriden in kernel
  config, then not all msgbuf pages will be dumped.  And most importantly,
  struct msgbuf itself will not be included.  Thus the dump would look
  corrupted/incomplete to tools like kgdb, dmesg, etc that try to access
  struct msgbuf as one of the first things they do when working on a crash
  dump.
