If anyone has any objections, please let me know. ------------------ From: Shawn Guo commit 1af997cad473d505248df6d9577183bb91f69670 upstream. Reboot starts failing on Poplar since commit 8424ecdde7df ("arm64: mm: Set ZONE_DMA size based on devicetree's dma-ranges"), which effectively changes zone_dma_bits from 30 to 32 for arm64 platforms that do not properly define dma-ranges in device tree. It's unclear how Poplar reboot gets broken by this change exactly, but a dma-ranges limiting zone_dma to the first 1 GB fixes the regression.
