  KVM: x86: fix emulation of "MOV SS, null selector" (2017-01-12 15:17:13 +0100)

----------------------------------------------------------------
* fix for module unload vs. deferred jump labels (note: there might be
  other buggy modules!)
* two NULL pointer dereferences from syzkaller
* CVE from syzkaller, very serious on 4.10-rc, "just" kernel memory
  leak on releases
* CVE from security@kernel.org, somewhat serious on AMD, less so on
  Intel
