Do you want me to enforce unsigned long alignment for all that are used by
locked BTS/BTR? There are quite a few/many those places. x86_capability
is one that is found in boot time. I tried to find split lock issues
in (very limited) tests; but so far only find the issue in x86_capability
in the tests.

Or you think we can push the patches upstream to allow broad test to find
and fix the issues?

Thanks.
