RISC-V: ACPI: NUMA: initialize all values of acpi_early_node_map to NUMA_NO_NODE

xiaobo55x · palmer-dabbelt · commit a445699879f9 · 2024-08-14T13:12:41.000-07:00
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.
