KVM fixes for v4.10-rc3

Browse source 
MIPS: (both for stable)
  - fix host kernel crashes when receiving a signal with 64-bit userspace
  - flush instruction cache on all vcpus after generating entry code
 
 x86:
  - fix NULL dereference in MMU caused by SMM transitions (for stable)
  - correct guest instruction pointer after emulating some VMX errors
  - minor cleanup
