Okie dokie.

Your branch at the above commit is not booting on n900.
> "arm/dma: flush i-cache and d-cache separately"
Not booting at this commit either.
> "arm/dma: call flush_cache_all() and don't do outer cache operation"
Not booting at this commit either.
Earlier commit f14f3479c0d7 ("arm/dma: re-enable to remap the CMA
area and flush cache before remapping") in you branch boots.
Then the following commit d6512d6d0171 ("Revert "arm/mm: disable
atomic_pool"") won't boot.
Also your tree at commit 6d0525cef962 ("arm/dma: remove i-cache
flush") with only commit d6512d6d0171 ("Revert "arm/mm: disable
atomic_pool"") reverted boots on n900.
So it seems the issue is currently at the atomic_pool_init()
related code?
Regards,
Tony
