Processors Affected: L1 Terminal Fault

Intel expects that the following products are potentially affected by these issues. However, processors that have the RDCL_NO bit set to one (1) in the IA32_ARCH_CAPABILITIES MSR are not susceptible to the L1TF speculative execution side channel method. Refer to Deep Dive: Intel Analysis of L1 Terminal Fault for complete details.
