Subject: fully convert arm to use dma-direct
Date: Thu, 21 Apr 2022 09:41:57 +0200 [thread overview]
Message-ID: <20220421074204.1284072-1-hch@lst.de> (raw)
Hi all,
arm is the last platform not using the dma-direct code for directly
mapped DMA. With the dmaboune removal from Arnd we can easily switch
arm to always use dma-direct now (it already does for LPAE configs
and nommu). I'd love to merge this series through the dma-mapping tree
as it gives us the opportunity for additional core dma-mapping
improvements.
