Do you have concern with the decision to expose the flag to /proc/cpuinfo?
The decision to expose the flag to /proc/cpuinfo was already discussed in [v1]. As suggested in the discussion [v1], I have added "buslock" to be enumerated in /proc/cpuinfo.
If you mean this:

I don't see any conclusion there.
I see Sean wanting to export information out of KVM to say what it supports without adding user ABI and I don't know how far that has come
Not very far :-(
but what you're doing here ain't it.
Just do:
#define X86_FEATURE_BUS_LOCK_THRESHOLD (15*32+29) /* Bus lock threshold */
and then later KVM can export this however it prefers.

Ack. I will remove "buslock".
