5.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Aneesh Kumar K.V <aneesh.kumar@xxxxxxxxxxxxx> commit 7b31f7dadd7074fa70bb14a53bd286ffdfc98b04 upstream. For both CONFIG_NUMA enabled/disabled use mem_topology_setup() to update max/min_low_pfn. This also adds min_low_pfn update to CONFIG_NUMA which was initialized to zero before. (mpe: Though MEMORY_START is == 0 for PPC64=y which is all possible NUMA=y systems) Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@xxxxxxxxxxxxx> Signed-off-by: Michael Ellerman <mpe@xxxxxxxxxxxxxx> Link: https://lore.kernel.org/r/20220704063851.295482-1-aneesh.kumar@xxxxxxxxxxxxx Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- arch/powerpc/mm/numa.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) --- a/arch/powerpc/mm/numa.c +++ b/arch/powerpc/mm/numa.c @@ -1162,6 +1162,9 @@ void __init mem_topology_setup(void) { int cpu; + max_low_pfn = max_pfn = memblock_end_of_DRAM() >> PAGE_SHIFT; + min_low_pfn = MEMORY_START >> PAGE_SHIFT; + /* * Linux/mm assumes node 0 to be online at boot.
