Synchronize reality with comment: The user_ldt_alloc function is supposed to return with dt_lock held. Due to broken locking in i386/xen/pmap.c, we drop dt_lock during the call to pmap_map_readonly and then pick it up again; this can be removed once the Xen pmap locking is fixed. MFC after: 3 days |
