Subject: linux-next: build failure after merge of the kvm tree

Hi all,

After merging the kvm tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

arch/x86/kvm/vmx/main.c:102:43: error: 'pi_has_pending_interrupt' undeclared here (not in a function)
  102 |         .dy_apicv_has_pending_interrupt = pi_has_pending_interrupt,
      |                                           ^~~~~~~~~~~~~~~~~~~~~~~~
arch/x86/kvm/vmx/main.c:131:27: error: 'vmx_pi_update_irte' undeclared here (not in a function); did you mean 'kvm_apic_update_irr'?
  131 |         .pi_update_irte = vmx_pi_update_irte,
      |                           ^~~~~~~~~~~~~~~~~~
      |                           kvm_apic_update_irr
arch/x86/kvm/vmx/main.c:132:32: error: 'vmx_pi_start_assignment' undeclared here (not in a function); did you mean 'kvm_arch_start_assignment'?
  132 |         .pi_start_assignment = vmx_pi_start_assignment,
      |                                ^~~~~~~~~~~~~~~~~~~~~~~
      |                                kvm_arch_start_assignment

Probably caused by commit

  5f18c642ff7e ("KVM: VMX: Move out vmx_x86_ops to 'main.c' to dispatch VMX and TDX")

interacting with commit

  699f67512f04 ("KVM: VMX: Move posted interrupt descriptor out of VMX code")

from the tip tree.

I have applied the following merge resolution patch.
