Subject: [PATCH 00/22] KVM: x86: Fill *_x86_ops via kvm-x86-ops.h

Use kvm-x86-ops.h to fill vmx_x86_ops and svm_x86_ops, with a bunch of
cleanup along the way to make that happen.  Aside from removing a lot of
boilerplate code, the part I most like about fill via kvm-x86-ops.h is
that it provides enforcement that (a) new kvm_x86_ops hooks get added to
kvm-x86-ops.h and (b) vendor code has to implement _something_, even if
it's a redirect to NULL, which provides documentation of what's going on.

Patch 01 isn't exactly necessary for this series, my hope is that Maxim's
bug fix for the AVIC race can go on top without introducing too much
conflict for either of us.

Sean Christopherson (22):
  KVM: x86: Drop unnecessary and confusing KVM_X86_OP_NULL macro
  KVM: x86: Move delivery of non-APICv interrupt into vendor code
  KVM: x86: Drop export for .tlb_flush_current() static_call key
  KVM: x86: Rename kvm_x86_ops pointers to align w/ preferred vendor
    names
  KVM: x86: Use static_call() for .vcpu_deliver_sipi_vector()
  KVM: VMX: Call vmx_get_cpl() directly in handle_dr()
  KVM: xen: Use static_call() for invoking kvm_x86_ops hooks
  KVM: nVMX: Refactor PMU refresh to avoid referencing
    kvm_x86_ops.pmu_ops
  KVM: x86: Uninline and export hv_track_root_tdp()
  KVM: x86: Unexport kvm_x86_ops
  KVM: x86: Use static_call() for copy/move encryption context ioctls()
  KVM: x86: Allow different macros for APICv, CVM, and Hyper-V
    kvm_x86_ops
  KVM: VMX: Rename VMX functions to conform to kvm_x86_ops names
  KVM: VMX: Use kvm-x86-ops.h to fill vmx_x86_ops
  KVM: x86: Move get_cs_db_l_bits() helper to SVM
  KVM: SVM: Rename svm_flush_tlb() to svm_flush_tlb_current()
  KVM: SVM: Remove unused MAX_INST_SIZE #define
  KVM: SVM: Rename AVIC helpers to use "avic" prefix instead of "svm"
  KVM: x86: Use more verbose names for mem encrypt kvm_x86_ops hooks
  KVM: SVM: Rename SEV implemenations to conform to kvm_x86_ops hooks
  KVM: SVM: Rename hook implementations to conform to kvm_x86_ops' names
  KVM: SVM: Use kvm-x86-ops.h to fill svm_x86_ops
