[PATCH/RESEND] arm64: defconfig: Enlarge CMA alignment to 2 MiB

Some IOMMUs (e.g. Renesas IPMMU/VMSA) support only page sizes of 4 KiB, 2 MiB, and 1 GiB. With the default setting of CONFIG_CMA_ALIGNMENT = 8, allocations larger than 1 MiB are aligned to a 1 MiB boundary only. Hence a 2 MiB allocation may not be aligned, leading to a mapping of 512 4 KiB

[PATCH v2] dmaengine: rcar-dmac: Widen DMA mask to 40 bits

By default, the DMA mask covers only the low 32-bit address space, which causes SWIOTLB on arm64 to fall back to a bounce buffer for DMA transfers involving memory outside the 32-bit address space. The R-Car DMA controller hardware supports a 40-bit address space, hence widen the DMA mask to 40
