kvm: vmx: Allow disabling virtual NMI support (2017-11-17 13:20:07 +0100)

----------------------------------------------------------------
Trimmed second batch of KVM changes for Linux 4.15

* GICv4 Support for KVM/ARM

All ARM patches were in next-20171113. I have postponed most x86 fixes
to 4.15-rc2 and UMIP to 4.16, but there are fixes that would be good to
have already in 4.15-rc1:

* re-introduce support for CPUs without virtual NMI (cc stable)
and allow testing of KVM without virtual NMI on available CPUs

* fix long-standing performance issues with assigned devices on AMD
(cc stable)
