  KVM: nVMX: Fix bad cleanup on error of get/set nested state IOCTLs (2018-09-20 18:54:08 +0200)

----------------------------------------------------------------
This pull request is slightly bigger than usual at this stage, but
I swear I would have sent it the same to Linus!  The main cause for
this is that I was on vacation until two weeks ago and it took a while
to sort all the pending patches between 4.20 and 4.21, test them and
so on.

It's mostly small bugfixes and cleanups, mostly around x86 nested
virtualization.  One important change, not related to nested
virtualization, is that the ability for the guest kernel to trap CPUID
instructions (in Linux that's the ARCH_SET_CPUID arch_prctl) is now
masked by default.  This is because the feature is detected through an
MSR; a very bad idea that Intel seems to like more and more.  Some
applications choke if the other fields of that MSR are not initialized
as on real hardware, hence we have to disable the whole MSR by default,
as was the case before Linux 4.12.
