  KVM: emulator: more strict rsm checks. (2020-09-12 12:22:55 -0400)

A bit on the bigger side, mostly due to me being on vacation, then busy,
then on parental leave, but there's nothing worrisome.

----------------------------------------------------------------
ARM:
- Multiple stolen time fixes, with a new capability to match x86
- Fix for hugetlbfs mappings when PUD and PMD are the same level
- Fix for hugetlbfs mappings when PTE mappings are enforced
  (dirty logging, for example)
- Fix tracing output of 64bit values

x86:
- nSVM state restore fixes
- Async page fault fixes
- Lots of small fixes everywhere

Lai Jiangshan (1):
      kvm x86/mmu: use KVM_REQ_MMU_SYNC to sync when needed

Marc Zyngier (2):
      KVM: arm64: Do not try to map PUDs when they are folded into PMD
      KVM: arm64: Fix address truncation in traces

Maxim Levitsky (4):
      SVM: nSVM: correctly restore GIF on vmexit from nesting after migration
      SVM: nSVM: setup nested msr permission bitmap on nested state load
      KVM: nSVM: more strict SMM checks when returning to nested guest
      KVM: emulator: more strict rsm checks.

Paolo Bonzini (1):
      Merge tag 'kvmarm-fixes-5.9-1' of git://git.kernel.org/.../kvmarm/kvmarm into HEAD

Peter Shier (1):
      KVM: nVMX: Update VMCS02 when L2 PAE PDPTE updates detected

Rustam Kovhaev (1):
      KVM: fix memory leak in kvm_io_bus_unregister_dev()

Vitaly Kuznetsov (3):
      KVM: x86: always allow writing '0' to MSR_KVM_ASYNC_PF_EN
      x86/kvm: properly use DEFINE_IDTENTRY_SYSVEC() macro
      x86/kvm: don't forget to ACK async PF IRQ

Wanpeng Li (2):
      KVM: SVM: avoid emulation with stale next_rip
      KVM: VMX: Don't freeze guest when event delivery causes an APIC-access exit
