Interrupts can be routed to maximal four virtual CPUs with one HW
EIOINTC interrupt controller model, since interrupt routing is encoded with
CPU bitmap and EIOINTC node combined method. Here add the EIOINTC virt
extension support so that interrupts can be routed to 256 vCPUs on
hypervisor mode. CP
Function kvm_para_has_feature() is to detect supported paravirt features,
it can be used by device driver to detect and enable paravirt features,
such as extioi irqchip driver can detect KVM_FEATURE_VIRT_EXTIOI and do
some optimization.

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
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.

All nodes need an explicit additionalProperties or unevaluatedProperties
unless a $ref has one that's false. Add missing additionalProperties
to fix dt_binding_check warning:

Hmm, bpf_uprobe_multi_link_attach() looks obviously wrong.
bpf_link_prime() is called after the
for (i = 0; i < cnt; i++) {
uprobe_register(...);
...
}
loop. If bpf_link_prime() fails, bpf_uprobe_multi_link_attach() just do
kvfree(uprobes) without
