Subsystem:
kexec, libnvdimm: non-volatile memory device subsystem, the rest, x86 architecture (32-bit and 64-bit) · Maintainers:

Change the callers of walk_iomem_res() with the following names to use walk_iomem_res(), instead. "ACPI Tables" "ACPI Non-volatile Storage" "Persistent Memory (legacy)" "Crash kernel" Note, the caller of walk_iomem_res() with "GART" will be removed in a later patch.
