Subject: [PATCH stable v5.10 0/7] arm64: Default to 32-bit wide ZONE_DMA
Date: Wed, 3 Mar 2021 15:33:12 +0800 [thread overview]
Message-ID: <20210303073319.2215839-1-jingxiangfeng@huawei.com> (raw)
Using two distinct DMA zones turned out to be problematic. Here's an
attempt go back to a saner default.
Ard Biesheuvel (1):
arm64: mm: Set ZONE_DMA size based on early IORT scan
Nicolas Saenz Julienne (6):
arm64: mm: Move reserve_crashkernel() into mem_init()
arm64: mm: Move zone_dma_bits initialization into zone_sizes_init()
of/address: Introduce of_dma_get_max_cpu_address()
of: unittest: Add test for of_dma_get_max_cpu_address()
arm64: mm: Set ZONE_DMA size based on devicetree's dma-ranges
mm: Remove examples from enum zone_type comment
