Robin Murphy a8a4c98fc9 x86/dma/amd-gart: Stop resizing dma_debug_entry pool ... dma-debug is now capable of adding new entries to its pool on-demand if the initial preallocation was insufficient, so the IOMMU_LEAK logic no longer needs to explicitly change the pool size. This does lose it the ability to save a couple of megabytes of RAM by reducing the pool size below its default, but it seems unlikely that that is a realistic concern these days (or indeed that anyone is actively debugging AGP drivers' DMA usage any more). Getting rid of dma_debug_resize_entries() will make room for further streamlining in the dma-debug code itself. Removing the call reveals quite a lot of cruft which has been useless for nearly a decade since commit 19c1a6f576 ("x86 gart: reimplement IOMMU_LEAK feature by using DMA_API_DEBUG"), including the entire 'iommu=leak' parameter, which controlled nothing except whether dma_debug_resize_entries() was called or not.
