  KVM: X86: Fix softlockup when get the current kvmclock (2017-11-21 00:11:31 +0100)

----------------------------------------------------------------
* GICv4 Support for KVM/ARM for v4.15
* x86 bugfixes: APIC, nested virtualization, IOAPIC, AMD+VFIO performance
issue with npt=1
* x86 guest UMIP support (real and emulated)

I am not including the host side of AMD SEV, because it wouldn't have gotten
enough time in linux-next even with a "regular-length" merge window.  It
will be in 4.16.
