+	  The MSR Tools project provides utilities to access x86
+	  processor MSRs and CPU ID directly.
+
+	  Those tools access the hardware through the
+	  /dev/cpu/<cpu#>/msr and /dev/cpu/<cpu#>/cpuid devices. This
+	  necessitates msr and cpuid support in the kernel, which
+	  means you need a kernel compiled with configuration options
+	  CONFIG_X86_CPUID and CONFIG_X86_MSR enabled.
