remove bogus GFP_DMA32 flags for dma allocations

remove bogus GFP_DMA32 flags for dma allocations

[Christoph Hellwig]

dma_alloc_* internally selects the zone to allocate from based on the
DMA mask.  Remove all explicit uses of GFP_DMA32 with dma_alloc_*.

Can you pick it up through the cpufreq tree?

Sure, I'll do that, thanks!

Applied "ASoC: intel: don't pass GFP_DMA32 to dma_alloc_coherent" to the asoc tree

[Mark Brown]

The patch

   ASoC: intel: don't pass GFP_DMA32 to dma_alloc_coherent

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

No but Mauros or Hans (in CC) can add it.

I'm adding it. Sorry for the delay. All those trips for MS/KS made
harder to handle it earlier.
