kvm: fix typo in flag name (2018-06-12 15:06:35 +0200)

Sorry for the late pull request, I really wanted to get the top four
patches in because a (wrong) patch for that bug was sent to the list
about a week ago. I didn't get as much attention/as many reviews as I
hoped for, but here they are anyway. They aren't complicated, only
a bit tedious, so I'm not (too) worried.

----------------------------------------------------------------
Small update for KVM.

* ARM: lazy context-switching of FPSIMD registers on arm64, "split"
regions for vGIC redistributor

* s390: cleanups for nested, clock handling, crypto, storage keys and
control register bits

* x86: many bugfixes, implement more Hyper-V super powers,
implement lapic_timer_advance_ns even when the LAPIC timer
is emulated using the processor's VMX preemption timer. Two
security-related bugfixes at the top of the branch.
