If a virtio_pci_device supports native PCI power management and has the
No_Soft_Reset bit set, then skip resetting and reinitializing the device
when suspending and restoring the device. This allows system-wide low
power states like s2idle to be used in systems with stateful virtio
devices that

When CONFIG_BUILTIN_RANGES is enable, the modules.builtin.ranges file
should be installed in the module install location.

When CONFIG_BUILTIN_RANGES is set, a linker map for vmlinux.o needs to
be generated. The generation of offset range data for builtin modules
depends on that linker map to know what offsets in an ELF section belong
to an object file for a particular builtin module.

The CONFIG_BUILTIN_RANGES option controls whether offset range data is
generated for kernel modules that are built into the kernel image.

The file modules.builtin names all modules that are built into the
kernel; this is checked by modprobe to not fail when trying to load
something built-in. But for tools which want to see which object files
make up each module, we want to help them with such a mapping as it
Especially for tracing applications, it is convenient to be able to
refer to a symbol using a pair and to be able
to translate an address into a pair. But
that does not work if the module is built into the kernel because the
