So you want to continue to allow the page allocator to return pages from anywhere, even when GFP_DMA is specified, just as though it was lowmem?
Why don't you actually address the problem with the driver you're complaining about with the patch below, which I already posted to you a few days ago?
If this arm driver is going to be using GFP_DMA unconditionally, it better require CONFIG_ZONE_DMA for it to actually be meaningful until such time as it can be removed if it's truly not needed or generalized to only specific pieces of hardware. --- drivers/net/irda/Kconfig | 1 + 1 files changed, 1 insertions(+), 0 deletions(-)
