KVM: Make KVM_INTEL depend on CPU_SUP_INTEL
PMU virtualization needs to talk to Intel-specific bits of perf; these are only available when CPU_SUP_INTEL=y. Fixes arch/x86/built-in.o: In function `atomic_switch_perf_msrs': vmx.c:(.text+0x6b1d4): undefined reference to `perf_guest_get_msrs' Reported-by: Ingo Molnar <mingo@elte.hu> Reported-by: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
