Hi Nishant,
I am facing the same problem to allocate a chunk of 4MB on omap3evm
using dma_alloc_coherent. I used the test driver mentioned here
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg11074.html
I applied the patch for
ioremap(24f11ec001920f1cfaeeed8e8b55725d900bbb56) suggested
: dma_alloc_coherent fragmentation

As per [1], GFP_TEMPORARY might be the right approach.. but yes,
Changing dummy to do:
