Problem with dma_alloc_coherent at linux-2.6.33-arm1 , withRealView platform,board PBX-A9 and armv7 instructions.

[David Yang]

I have passed the test,when using wmb() and without PATCH 0/3;

But,I have a  doubt : if I use the wmb(), then the l2x0.c 's patch is
not needed?


I will test the PATCH v3 0/3  tomorrow, without using wmb();



Thanks!
