[PATCH 0/6] KVM: x86: Clean up "force immediate exit" code

[Sean Christopherson <seanjc@google.com>]

Plumb "force_immediate_exit" into the kvm_entry() tracepoint, as
suggested by Maxim, and then follow that up with cleanups that are made
possible by having force_immediate_exit made available to .vcpu_run(),
e.g. VMX can use the on-stack param instead of what is effectively a
temporary field in vcpu_vmx.

Sean Christopherson (6):
  KVM: x86: Plumb "force_immediate_exit" into kvm_entry() tracepoint
  KVM: VMX: Re-enter guest in fastpath for "spurious" preemption timer
    exits
  KVM: VMX: Handle forced exit due to preemption timer in fastpath
  KVM: x86: Move handling of is_guest_mode() into fastpath exit handlers
  KVM: VMX: Handle KVM-induced preemption timer exits in fastpath for L2
  KVM: x86: Fully defer to vendor code to decide how to force immediate
    exit
