Hi Greg - I successfully tested this release candidate in x86_64 Hyper-V
Azure VMs with speculation controls both enabled and disabled.
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 v5.10.118
release (there were no regressions).
