Speculation controls are passed through to the guest and, of particular interest for this release candidate, set the FB_CLEAR bit in the IA32_ARCH_CAPABILITIES MSR. The FB_CLEAR bit's presence is accurately conveyed in the kernel log messages during boot and in the /sys/devices/system/cpu/vulnerabilities/mmio_stale_data file. I did a full LTP run in both scenarios (the results were the same) and also compared the results to a previous run against the v5.15.45 release (there were no regressions).
