x86/KVM/VMX: Don't set l1tf_flush_l1d from vmx_handle_external_intr()
For VMEXITs caused by external interrupts, vmx_handle_external_intr() indirectly calls into the interrupt handlers through the host's IDT. It follows that these interrupts get accounted for in the kvm_cpu_l1tf_flush_l1d per-cpu flag. The subsequently executed vmx_l1d_flush() will thus be aware that some interrupts have happened and conduct a L1d flush anyway. Setting l1tf_flush_l1d from vmx_handle_external_intr() isn't needed anymore. Drop it. Signed-off-by: Nicolai Stange <nstange@suse.de> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
