Pull kvm fixes from Paolo Bonzini:
 "The most intrusive change is reverting a commit from 7.3-rc1 that made
  struct kvm a bit too large, and fixing the same issue otherwise.

  There are again a lot of selftests lines; the sheer number of commits
  is not small but I don't expect much more for 7.3 due to people
  travelling to Plumbers next week.

  ARM:

   - Take a reference on the last IRQ loaded into an LR to prevent it
     from being freed while running the guest (Marc Zyngier)

   - Ensure that the ITS MOVALL command only affects LPIs that were
     previously affined to the source redistributor (Marc Zyngier)

   - Fix + test for honoring the host's trap configuration when running
     non-protected VMs while KVM is in protected mode (Fuad Tabba)

   - Use the host stage-1 mapping granularity for VM_PFNMAP mappings at
     stage-2 (Mostafa Saleh)

  x86:

  Various bugfixes where the guest could do stupid things on purpose to
  cause problems in the host:

   - Failed VMRUNs can cause pending TLB flushes to be dropped, and in
     general some actions done through VMCB control fields have to be
     redone if VMRUN fails

   - Toggling MSR interceptions or eVMCS execution controls can cause
     the host to use a stale MSR permission bitmap

   - Bad page tables can cause a WARN.

  Also fix issues in last week's pull request (my fault, for changing
  email workflow and thus missing feedback sent to kvm@ but not LKML).

  Generic:

   - Take kvm_lock when creating vCPUs. For almost two decades everybody
     thought it was not done for some unspecified performance reasons,
     but in reality it was only done because kvm_lock was originally a
     spinlock.

     This is a better fix than 97d65b544f48 ("KVM: Check for duplicate
     vcpu_id as early as possible", from the 7.3 merge window), and does
     not waste 2K per VM, hence its inclusion here"
