[PATCH] ACPI: NUMA: initialize all values of acpi_early_node_map to NUMA_NO_NODE
Posted by Haibo Xu 1 year, 6 months ago
Currently, only acpi_early_node_map[0] was initialized to NUMA_NO_NODE.
To ensure all the values were properly initialized, switch to initialize
all of them to NUMA_NO_NODE.

Applied arm64 hunk to arm64 (for-next/acpi), thanks!

Thanks, but I think Reported-by, or both Reported-by and Suggested-by,
is more appropriate. Also, I agree with Sunil that we probably need to
split this patch for arm64 and riscv in order to add appropriate Fixes
tags.

The change looks good to me. However, I was wondering whether it needs
"Fixes" tag in which case I think you will have to split this patch into
two.

Otherwise,
