  Merge branch 'kvm-insert-lfence' into kvm-master (2018-01-11 18:20:48 +0100)


* user-triggerable use-after-free in HPT resizing
* stale TLB entries in the guest
* trap-and-emulate (PR) KVM guests failing to start under pHyp

* Another "Spectre" fix.
* async pagefault fix
* Revert an old fix for x86 nested virtualization, which turned out
  to do more harm than good
* Check shrinker registration return code, to avoid warnings from
  upcoming 4.16 -mm patches
