This commit adds the ability for archs to export per-vcpu information via a new per-vcpu dir in the VM's debugfs directory. If kvm_arch_has_vcpu_debugfs() returns true, then KVM will create a vcpu dir for each vCPU in the VM's debugfs directory. Then kvm_arch_create_vcpu_debugfs() is responsible for populating each vcpu directory with arch specific entries. The per-vcpu path in debugfs will look like: /sys/kernel/debug/kvm/29162-10/vcpu0 /sys/kernel/debug/kvm/29162-10/vcpu1 This is all arch specific for now because the only user of this interface (x86) wants to export x86-specific per-vcpu information to user-space.
