fatal error: kernel-interfaces/readahead.h: No such file or directory

Hello. I'm trying to compile the kernel but there is a problem and related to the "filemap.c" in mm folder in kernel-ml-linux folder. in "filemap.c" file there is "#include <kernel-interfaces/readahead.h>"(line 47) but in there is no kernel-interfaces folder in kernel-ml-linux folder. Out of kernel-ml-linux folder, I mean in kernel-ml folder there is a kernel-interfaces folder but it has no readahead.h file. Also in include folder, there is a kernel-interfaces folder that has readahead.h file. What is the problem. Is needed to change the address in "filemap.c" file? Another folders in kernel-ml-linux like "arch" folder has no problem and compile successfully.
