What base kernel version is this against? I noticed that in .31 struct mce
doesn't have a res1 field anymore, and hence there's no place to
(compatibly) store mc_bank->mc_ctrl2. Do you have any plans on how
to address this? Additionally, the new use of the space previously
consumed by the res1 field seems to put under question whether that
was actually forward compatible (namely, whether it might confuse
newer user space tools).

Thanks, Jan
