timerqueue_del() uses rbtree, and #define rb_parent(r) ((struct rb_node *)((r)->__rb_parent_color & ~3)) relies on all objects being 4-byte aligned. But your patch broke that assumption on m68k, where the default alignment is 2-byte. Andrew: please drop this patch.
Yeah that's too bad. I'll send a patch improving the comment around the alignment once the patch is dropped. Thanks, Davidlohr
