ACPI: NUMA: Use correct type for printing addresses on i386-PAE
The addresses of NUMA nodes are not printed correctly on i386-PAE which is misleading. Here is a debian9-32bit with PAE in a QEMU guest having more than 4G of memory: qemu-system-i386 \ -hda /var/lib/libvirt/images/debian32.qcow2 \ -m 5G \ -enable-kvm \ -smp 10 \ -numa node,mem=512M,nodeid=0,cpus=0 \ -numa node,mem=512M,nodeid=1,cpus=1 \ -numa node,mem=512M,nodeid=2,cpus=2 \ -numa node,mem=512M,nodeid=3,cpus=3 \ -numa node,mem=512M,nodeid=4,cpus=4 \ -numa node,mem=512M,nodeid=5,cpus=5 \ -numa node,mem=512M,nodeid=6,cpus=6 \ -numa node,mem=512M,nodeid=7,cpus=7 \ -numa node,mem=512M,nodeid=8,cpus=8 \ -numa node,mem=512M,nodeid=9,cpus=9 \ -serial stdio Because of the wrong value type, it prints as below: [ 0.021049] ACPI: SRAT Memory (0x0 length 0xa0000) in proximity domain 0 enabled [ 0.021740] ACPI: SRAT Memory (0x100000 length 0x1ff00000) in proximity domain 0 enabled [ 0.022425] ACPI: SRAT Memory (0x20000000 length 0x20000000) in proximity domain 1 enabled [ 0.023092] ACPI: SRAT Memory (0x40000000 length 0x20000000) in proximity domain 2 enabled [ 0.023764] ACPI: SRAT Memory (0x60000000 length 0x20000000) in proximity domain 3 enabled [ 0.024431] ACPI: SRAT Memory (0x80000000 length 0x20000000) in proximity domain 4 enabled [ 0.025104] ACPI: SRAT Memory (0xa0000000 length 0x20000000) in proximity domain 5 enabled [ 0.025791] ACPI: SRAT Memory (0x0 length 0x20000000) in proximity domain 6 enabled [ 0.026412] ACPI: SRAT Memory (0x20000000 length 0x20000000) in proximity domain 7 enabled [ 0.027118] ACPI: SRAT Memory (0x40000000 length 0x20000000) in proximity domain 8 enabled [ 0.027802] ACPI: SRAT Memory (0x60000000 length 0x20000000) in proximity domain 9 enabled The upper half of the start address of the NUMA domains between 6 and 9 inclusive was cut, so the printed values are incorrect. Fix the value type, to get the correct values in the log as follows: [ 0.023698] ACPI: SRAT Memory (0x0 length 0xa0000) in proximity domain 0 enabled [ 0.024325] ACPI: SRAT Memory (0x100000 length 0x1ff00000) in proximity domain 0 enabled [ 0.024981] ACPI: SRAT Memory (0x20000000 length 0x20000000) in proximity domain 1 enabled [ 0.025659] ACPI: SRAT Memory (0x40000000 length 0x20000000) in proximity domain 2 enabled [ 0.026317] ACPI: SRAT Memory (0x60000000 length 0x20000000) in proximity domain 3 enabled [ 0.026980] ACPI: SRAT Memory (0x80000000 length 0x20000000) in proximity domain 4 enabled [ 0.027635] ACPI: SRAT Memory (0xa0000000 length 0x20000000) in proximity domain 5 enabled [ 0.028311] ACPI: SRAT Memory (0x100000000 length 0x20000000) in proximity domain 6 enabled [ 0.028985] ACPI: SRAT Memory (0x120000000 length 0x20000000) in proximity domain 7 enabled [ 0.029667] ACPI: SRAT Memory (0x140000000 length 0x20000000) in proximity domain 8 enabled [ 0.030334] ACPI: SRAT Memory (0x160000000 length 0x20000000) in proximity domain 9 enabled Signed-off-by: Chao Fan <fanc.fnst@cn.fujitsu.com> [ rjw: Subject & changelog ] Signed-off-by: Rafael J.
