I see it on my desktop as /usr/include/asm/msr-index.h and it's been there at least four years - and as such it's part of the UAPI. I don't think you can remove it unless you can guarantee there are no userspace users.

I keep it in the v2 of the series, but the maintainer, Borislav Petkov, asks me to un-export it.

I will follow the maintainer decision.

I'm not the maintainer. I simply think that exporting that file was wrong because it if we change something in it, we will break userspace. And that should not happen - if userspace needs MSRs, it should do its own defines.
