Andrew Morton 6536e3123e mm: fix warnings regarding enum migrate_mode
sparc64 allmodconfig:

In file included from include/linux/compat.h:15,
                 from /usr/src/25/arch/sparc/include/asm/siginfo.h:19,
                 from include/linux/signal.h:5,

include/linux/fs.h:618: warning: parameter has incomplete type

It seems that my sparc64 compiler (gcc-3.4.5) doesn't like the forward
declaration of enums.

Fix this by moving the "enum migrate_mode" definition into its own header
file.
