[Bug 490371] Re: Atomic operations not safe for ARMv7, Thumb-2 and multicore

[Jani Monoses]

The patch in Ubuntu 11.04 is backported from upstream Qt4.8. If upstream is mistaken, one of the persons who actually have a clue about the fine details of ARMv7 memory barriers (not me)  should educate upstream as was suggested in a previous comment.
The Ubuntu bug tracker may be watched but unless the discussion happens upstream there is no guarantee a consensus will be reached.
