[PATCH 1/4] KVM: x86: reserve bit 8 of non-leaf PDPEs and PML4Es in 64-bit mode on AMD

Bit 8 would be the "global" bit, which does not quite make sense for non-leaf page table entries. Intel ignores it; AMD ignores it in PDEs, but reserves it in PDPEs and PML4Es. The SVM test is relying on this behavior, so enforce it. Signed-off-by: Paolo Bonzini --- arch/x86/kvm/cpuid.h | 8
