David Howells ed5e5894b2 nommu: fix SYSV SHM for NOMMU ... Commit c4caa77815 ("file ->get_unmapped_area() shouldn't duplicate work of get_unmapped_area()") broke SYSV SHM for NOMMU by taking away the pointer to shm_get_unmapped_area() from shm_file_operations. Put it back conditionally on CONFIG_MMU=n. file->f_ops->get_unmapped_area() is used to find out the base address for a mapping of a mappable chardev device or mappable memory-based file (such as a ramfs file). It needs to be called prior to file->f_ops->mmap() being called.
