Greg Kroah-Hartman a27fb6d983 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 4.19 and 4.20, 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.
