  - iommu/vt-d: avoid invalid memory access via node_online(NUMA_NO_NODE) KASAN reports: [ 4.668325][ T0] BUG:
    KASAN: wild-memory-access in dmar_parse_one_rhsa (arch/x86/include/asm/bitops.h:214     arch/x86/include/asm/bitops.h:226 include/asm-generic/bitops/instrumented-non-atomic.h:142     include/linux/nodemask.h:415 drivers/iommu/intel/dmar.c:497) [ 4.676149][ T0] Read of size 8 at addr     1fffffff85115558 by task swapper/0/0 [ 4.683454][ T0] [ 4.685638][ T0] CPU: 0 PID: 0 Comm: swapper/0 Not     tainted 5.19.0-rc3-00004-g0e862838f290 #1 [ 4.694331][ T0] Hardware name: Supermicro     SYS-5018D-FN4T/X10SDV-8C-TLN4F, BIOS 1.1 03/02/2016 [ 4.703196][ T0] Call Trace: [ 4.706334][ T0] <TASK> [     4.709133][ T0] ? dmar_parse_one_rhsa (arch/x86/include/asm/bitops.h:214 arch/x86/include/asm/bitops.h:226     include/asm-generic/bitops/instrumented-non-atomic.h:142 include/linux/nodemask.h:415     drivers/iommu/intel/dmar.c:497) after converting the type of the first argument (@nr, bit number) of     arch_test_bit() from `long` to `unsigned long`[0]. Under certain conditions (for example, when ACPI NUMA     is disabled via command line), pxm_to_node() can return %NUMA_NO_NODE (-1). It is valid 'magic' number of     NUMA node, but not valid bit number to use in bitops. node_online() eventually descends to test_bit()     without checking for the input, assuming it's on caller side (which might be good for perf-critical     tasks). There, -1 becomes %ULONG_MAX which leads to an insane array index when calculating bit position in     memory. For now, add an explicit check for @node being not %NUMA_NO_NODE before calling test_bit(). The     actual logics didn't change here at all.
