Subject: [RFC PATCH v3 00/19] RFC: nested AVIC

This is V3 of my nested AVIC patches.

I fixed few more bugs, and I also split the cod insto smaller patches.

Review is welcome!

Best regards,
	Maxim Levitsky

Maxim Levitsky (19):
  KVM: x86: document AVIC/APICv inhibit reasons
  KVM: x86: inhibit APICv/AVIC when the guest and/or host changes apic
    id/base from the defaults.
  KVM: x86: SVM: remove avic's broken code that updated APIC ID
  KVM: x86: mmu: allow to enable write tracking externally
  x86: KVMGT: use kvm_page_track_write_tracking_enable
  KVM: x86: mmu: add gfn_in_memslot helper
  KVM: x86: mmu: tweak fast path for emulation of access to nested NPT
    pages
  KVM: x86: SVM: move avic state to separate struct
  KVM: x86: nSVM: add nested AVIC tracepoints
  KVM: x86: nSVM: implement AVIC's physid/logid table access helpers
  KVM: x86: nSVM: implement shadowing of AVIC's physical id table
  KVM: x86: nSVM: make nested AVIC physid write tracking be aware of the
    host scheduling
  KVM: x86: nSVM: wire nested AVIC to nested guest entry/exit
  KVM: x86: rename .set_apic_access_page_addr to reload_apic_access_page
  KVM: x86: nSVM: add code to reload AVIC physid table when it is
    invalidated
  KVM: x86: nSVM: implement support for nested AVIC vmexits
  KVM: x86: nSVM: implement nested AVIC doorbell emulation
  KVM: x86: SVM/nSVM: add optional non strict AVIC doorbell mode
  KVM: x86: nSVM: expose the nested AVIC to the guest
