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.
