Probably all fixed with " [PATCH 1/3] Revert "lto: Make asmlinkage
__visible", see https://lkml.org/lkml/2014/4/1/757. (At least, similar
warnings were gone here with that patch applied.) Not sure were that
patch is queued.

Fixed by "[PATCH] Revert "drm/i915: fix build warning on 32-bit (v2)"",
see https://lkml.org/lkml/2014/4/7/119 . Is that one queued somewhere?

First reported (for linux-next it seems) in
https://lkml.org/lkml/2014/3/26/30 . Fix is currently discussed in the
(short) thread starting at https://lkml.org/lkml/2014/4/10/633 .
