[PATCH] x86/kvm/vmx: Fix GPF on reading vmentry_l1d_flush

When EPT is not enabled, reading /sys/module/kvm_intel/parameters/vmentry_l1d_flush causes general protection fault in vmentry_l1d_flush_get() due to access beyond the end of the array vmentry_l1d_param[]. Signed-off-by: Minoura Makoto --- arch/x86/include/asm/vmx.h | 1 + arch/x86/kvm/vmx.c
