[PATCH 0/2] Preparation to .map_page and .unmap_page removal

From: Leon Romanovsky
Date: Thu Jul 17 2025 - 02:47:35 EST


This is followup to "dma-mapping: migrate to physical address-based API"
series https://lore.kernel.org/all/cover.1750854543.git.leon@xxxxxxxxxx/

These preparation changes are limited to DMA subsystem to avoid possible
complications with submission to multiple trees.

Thanks
