hm, actually...  Add two new initcall levels, one for populate_rootfs() and
one for things which want to come after it (ie: drivers which want to
access the filesytem):

 #define core_initcall(fn)		__define_initcall("1",fn,1)
 #define core_initcall_sync(fn)		__define_initcall("1s",fn,1s)
 #define postcore_initcall(fn)		__define_initcall("2",fn,2)
 #define postcore_initcall_sync(fn)	__define_initcall("2s",fn,2s)
 #define arch_initcall(fn)		__define_initcall("3",fn,3)
 #define arch_initcall_sync(fn)		__define_initcall("3s",fn,3s)
 #define subsys_initcall(fn)		__define_initcall("4",fn,4)
 #define subsys_initcall_sync(fn)	__define_initcall("4s",fn,4s)
 #define fs_initcall(fn)		__define_initcall("5",fn,5)
 #define fs_initcall_sync(fn)		__define_initcall("5s",fn,5s)
 #define device_initcall(fn)		__define_initcall("6",fn,6)
 #define device_initcall_sync(fn)	__define_initcall("6s",fn,6s)
 #define late_initcall(fn)		__define_initcall("7",fn,7)
 #define late_initcall_sync(fn)		__define_initcall("7s",fn,7s)
+#define populate_rootfs_initcall ...
+#define post_populate_rootfs_initcall ...
