when i worked at BMW as a technician some woman came in with her car saying theres white smoke out of the exhaust, i checked the oil level and it was over done, i opened the oil cap and i couldnt even see the rockers as it was filled up with so much oil even there was oil being pushed out of the dipstick.. drained it and flushed it all out and car was normal again!! this happened a few times with other people!!! ALSO white smoke is another indicator of engine damage, i.e. water emulsification with oil, head gasket water gallery damage, check for water loss in the radiator..... if yes then..mmmmmmmmmm
just hope you messed up (but not too much) with over filling oil...
