At build time, create the file modules.builtin.ranges that will hold
address range data of the built-in modules that can be used by tracers.
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
The modules.builtin.ranges offset range data for builtin modules is
generated at compile time based on the list of built-in modules and

KVM_FEATURE_VIRT_EXTIOI is paravirt feature defined with EXTIOI
interrupt controller, it can route interrupt to 256 vCPUs and CPU
interrupt pin IP0-IP7. Now EXTIOI irqchip is emulated in user space
rather than kernel space, here interface is provided for VMM to pass
this feature to KVM hypervisor.
Export kernel paravirt features to user space, so that VMM can control
the single paravirt feature. By default paravirt features will be the same
with kvm supported features if VMM does not set it.
Also a new feature KVM_FEATURE_VIRT_EXTIOI is added which can be set from
user space. This feature i
Interrupts can be routed to maximal four virtual CPUs with one HW
