  "message": "x86/KVM/VMX: Add L1D flush logic\n\nAdd the logic for flushing L1D on VMENTER. The flush depends on the static\nkey being enabled and the new l1tf_flush_l1d flag being set.\n\nThe flags is set:\n - Always, if the flush module parameter is \u0027always\u0027\n\n - Conditionally at:\n   - Entry to vcpu_run(), i.e. after executing user space\n\n   - From the sched_in notifier, i.e. when switching to a vCPU thread.\n\n   - From vmexit handlers which are considered unsafe, i.e. where\n     sensitive data can be brought into L1D:\n\n     - The emulator, which could be a good target for other speculative\n       execution-based threats,\n\n     - The MMU, which can bring host page tables in the L1 cache.\n     \n     - External interrupts\n\n     - Nested operations that require the MMU (see above). That is\n       vmptrld, vmptrst, vmclear,vmwrite,vmread.\n\n     - When handling invept,invvpid\n\n[ tglx: Split out from combo patch and reduced to a single flag ]\n\nSigned-off-by: Paolo Bonzini \u003cpbonzini@redhat.com\u003e\nSigned-off-by: Konrad Rzeszutek Wilk \u003ckonrad.wilk@oracle.com\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n",
