Signed-off-by: Anatoly Burakov --- Notes: v4: - Use new memzone flag instead of new API - Remove experimental API from build files v3: - Added this driver to the list of modified drivers - Add experimental API to build files v3: - Added this patch All memzone reserve calls then check physical addresses, so this looks like they're reserving DMA memory.
