Crud.  OK, v2, probably just for Andrew for now (?).




From: Randy Dunlap <randy.dunlap@oracle.com>

The COMPAT_BRK kconfig symbol does not depend on EMBEDDED,
but it is in the midst of the EMBEDDED menu symbols, so it mucks
up the EMBEDDED menu.  Fix by moving it to just after all of
the EMBEDDED menu symbols.  Also, ANON_INODES has a similar
problem, so move it to just above the EMBEDDED menu items
since it is used in the EMBEDDED menu.
