This caused a regression on big -machines that need big CMA and crashkernel reservations. Note that -ZONE_DMA is only 1GB big. - -Restore the previous behavior as the wide majority of devices are OK -with reserving these in ZONE_DMA32. The ones that need them in ZONE_DMA -will configure it explicitly. - -Fixes: 1a8e1cef7603 ("arm64: use both ZONE_DMA and ZONE_DMA32") -Reported-by: Qian Cai <cai@lca.pw> -Signed-off-by: Nicolas Saenz Julienne <nsaenzjulienne@suse.de> -Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> ---- - arch/arm64/mm/init.c | 4 ++-- - 1 file changed, 2 insertions(+), 2 deletions(-) - ---- a/arch/arm64/mm/init.c -+++ b/arch/arm64/mm/init.c -@@ -85,7 +85,7 @@ static void __init reserve_crashkernel(v - - if (crash_base == 0) { - /* Current arm64 boot protocol requires 2MB alignment */ -- crash_base = memblock_find_in_range(0, ARCH_LOW_ADDRESS_LIMIT, -+ crash_base = memblock_find_in_range(0, arm64_dma32_phys_limit, - crash_size, SZ_2M); - if (crash_base == 0) { - pr_warn("cannot allocate crashkernel (size:0x%llx)\n", -@@ -461,7 +461,7 @@ void __init arm64_memblock_init(void) - - high_memory = __va(memblock_end_of_DRAM() - 1) + 1; - -- dma_contiguous_reserve(arm64_dma_phys_limit ? : arm64_dma32_phys_limit); -+ dma_contiguous_reserve(arm64_dma32_phys_limit); - } - - void __init bootmem_init(void) |
