Re: [PATCH v6 8/8] dma: swiotlb: Remove SWIOTLB_ANY

[sashiko-bot@kernel.org]

> swiotlb pools are currently allocated below the architecture's low
> address limit by default. SWIOTLB_ANY overrides this and permits
> allocation anywhere in directly mapped memory.
> 
> SWIOTLB_INIT_ADDRESSING_LIMIT now explicitly identifies callers which
> need a pool that is reachable by devices with limited DMA addressing.
> Use it as the placement constraint and remove SWIOTLB_ANY.
> 
> This changes the default behavior for callers which do not set either
> flag. Previously, omitting SWIOTLB_ANY placed the default pool below the
> architecture's low address limit and also constrained dynamically
> allocated pools to the same range. After this change, omitting
> SWIOTLB_INIT_ADDRESSING_LIMIT permits both static and dynamic pools to
> use any directly mapped memory.
