Subject: [PATCH 00/23] SVM queue for 5.13

This includes:

- vmcb01/vmcb02 split.  Unfortunately this is a wash in terms of
  nested vmexit speed, which I did not expect.  However, keeping
  the code more in sync with VMX is useful anyway.

- move common VMX/SVM emulation to x86.c (Sean)

- support for vSPEC_CTRL (Babu)

Paolo


Babu Moger (1):
  x86/cpufeatures: Add the Virtual SPEC_CTRL feature

Cathy Avery (3):
  KVM: SVM: Use a separate vmcb for the nested L2 guest
  KVM: nSVM: Track the physical cpu of the vmcb vmrun through the vmcb
  KVM: nSVM: Track the ASID generation of the vmcb vmrun through the
    vmcb

Krish Sadhukhan (1):
  KVM: nSVM: Add missing checks for reserved bits to
    svm_set_nested_state()

Maxim Levitsky (1):
  KVM: nSVM: always use vmcb01 to for vmsave/vmload of guest state

Paolo Bonzini (8):
  KVM: nSVM: rename functions and variables according to vmcbXY
    nomenclature
  KVM: nSVM: do not copy vmcb01->control blindly to vmcb02->control
  KVM: nSVM: do not mark all VMCB01 fields dirty on nested vmexit
  KVM: nSVM: do not mark all VMCB02 fields dirty on nested vmexit
  KVM: nSVM: only copy L1 non-VMLOAD/VMSAVE data in
    svm_set_nested_state()
  KVM: SVM: merge update_cr0_intercept into svm_set_cr0
  KVM: SVM: move VMLOAD/VMSAVE to C code
  KVM: SVM: Add support for Virtual SPEC_CTRL

Sean Christopherson (9):
  KVM: x86: Move nVMX's consistency check macro to common code
  KVM: nSVM: Trace VM-Enter consistency check failures
  KVM: SVM: Pass struct kvm_vcpu to exit handlers (and many, many other
    places)
  KVM: nSVM: Add VMLOAD/VMSAVE helper to deduplicate code
  KVM: x86: Move XSETBV emulation to common code
  KVM: x86: Move trivial instruction-based exit handlers to common code
  KVM: x86: Move RDPMC emulation to common code
  KVM: SVM: Don't manually emulate RDPMC if nrips=0
  KVM: SVM: Skip intercepted PAUSE instructions after emulation
