x86: kvm: hide the unused 'cpu' variable
The local variable was newly introduced but is only accessed in one place on x86_64, but not on 32-bit: arch/x86/kvm/vmx.c: In function 'vmx_save_host_state': arch/x86/kvm/vmx.c:2175:6: error: unused variable 'cpu' [-Werror=unused-variable] This puts it into another #ifdef. Fixes: 35060ed6 ("x86/kvm/vmx: avoid expensive rdmsr for MSR_GS_BASE") Signed-off-by: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>
