That makes no sense. I sent the email before completing the sentence. I
meant:

```
          * Microcode updates may change CPUID or MSRs. We need to reload
          * the subset of boot_cpu_data we got on early_cpu_init() before
          * continuing. Notably tsx_init() needs an up to date MSR_ARCH_CAPS.
```
