  KVM: x86: Fix off-by-one error in kvm_vcpu_ioctl_x86_setup_mce (2020-05-15 13:48:56 -0400)

----------------------------------------------------------------
A new testcase for guest debugging (gdbstub) that exposed a bunch of
bugs, mostly for AMD processors.  And a few other x86 fixes.

----------------------------------------------------------------
Babu Moger (1):
      KVM: x86: Fix pkru save/restore when guest CR4.PKE=0, move it to x86.c

Jim Mattson (1):
      KVM: x86: Fix off-by-one error in kvm_vcpu_ioctl_x86_setup_mce

Paolo Bonzini (6):
      KVM: x86: fix DR6 delivery for various cases of #DB injection
      KVM: nSVM: trap #DB and #BP to userspace if guest debugging is on
      KVM: SVM: keep DR6 synchronized with vcpu->arch.dr6
      KVM: x86, SVM: isolate vcpu->arch.dr6 from vmcb->save.dr6
      KVM: VMX: pass correct DR6 for GD userspace exit
      Merge branch 'kvm-amd-fixes' into HEAD

Peter Xu (4):
      KVM: X86: Declare KVM_CAP_SET_GUEST_DEBUG properly
      KVM: X86: Set RTM for DB_VECTOR too for KVM_EXIT_DEBUG

Suravee Suthikulpanit (2):
      KVM: Introduce kvm_make_all_cpus_request_except()
      KVM: SVM: Disable AVIC before setting V_IRQ
