Cover letter [PATCH v1 0/9] Remove DMA .map_page and .unmap_page callbacks
Changelog:
v1:
* Fixed wrong offset in alpha conversion patch.
v0: https://lore.kernel.org/all/[email protected]
Hi,
This series continues following two series:
1. "dma-mapping: migrate to physical address-based API"
https://lore.kernel.org/all/[email protected]
2. "Preparation to .map_page and .unmap_page removal" Preparation to .map_page and .unmap_page removal
In this series, the DMA .map_page/.unmap_page callbacks are converted to newly introduced .map_phys/.unmap_phys interfaces. This conversion allows us to reduce or eliminate (for certain ARCHs) use of struct pages in DMA path.
Thanks
