Can you replace:

#ifdef MD_BITMAP_SUPPORT
        /* get the component's superblock */
+       read_disk_sb(rdev);
        sb = (mdp_super_t *)page_address(rdev->sb_page);


(untested - you are guinea pig).

It looks as though one can skip that if rdev->sb_page is non-null and
if rdev->sb_loaded is nonzero. But try that first.
