Patch-mainline: v4.17-rc1
Subject: x86/kvm: rename HV_X64_MSR_APIC_ASSIST_PAGE to HV_X64_MSR_VP_ASSIST_PAGE
Git-commit: d4abc577bb03a3facc0f21cc1f2c6b27cd0f5d07
References: bsc#1107207
MIME-Version: 1.0

The assist page has been used only for the paravirtual EOI so far, hence
the "APIC" in the MSR name. Renaming to match the Hyper-V TLFS where it's
called "Virtual VP Assist MSR".
