Anyway, why do you need the spin lock there (and not mutex)? As I think you are 
still trying to avoid the problem instead of fixing it. Removing GFP_WAIT 
(fsl_diu_alloc) doesn't seem to me as mm friendly solution, especially if you 
allocate that much memory and you can sleep. But I might be wrong, you may need 
the spinlock...
