Hi Kishon,

I rebased my rcar-endpoint patches on endpoint branch, which has
support for streaming DMA API support, with this  read/write/copy
tests failed, to make sure nothing hasn't changed on my driver I
reverted the streaming DMA API patch
74b9b4da84c71418ceeaaeb78dc790376df92fea "misc: pci_endpoint_test: Use
streaming DMA APIs for buffer allocation" and tests began to pass
again.

If add a GFP_DMA flag for kzalloc (with streaming DMA), the test cases
for read/write/copy pass as expected.

Could you please through some light why this could be happening.

Cheers,
--Prabhakar Lad
