wahrenstandGreg Kroah-Hartman bf96d362aa ARM: 9323/1: mm: Fix ARCH_LOW_ADDRESS_LIMIT when CONFIG_ZONE_DMA ...

[ Upstream commit 399da29ff5 ]

Configuring VMSPLIT_2G + LPAE on Raspberry Pi 4 leads to SWIOTLB
buffer allocation beyond platform dma_zone_size of SZ_1G, which
results in broken SD card boot.

So fix this be setting ARCH_LOW_ADDRESS_LIMIT in CONFIG_ZONE_DMA
case.
