Subject: arm swiotlb fix
Date: Mon, 5 Aug 2019 10:56:36 +0300 [thread overview]
Message-ID: <20190805075637.5373-1-hch@lst.de> (raw)
Hi all,
my commit to add swiotlb to arm failed to initialize the atomic pool,
which is needed for GFP_ATOMIC allocations on non-coherent devices.
These are fairly rare, but exist so we should wire it up. For 5.4
I plan to move the initilization to the common dma-remap code so it
won't be missed for other architectures.
