Hi Michael,
Here are 2 patches my brother and I prepared together.
There are still some pages that we couldn't find with grep,
so I'll send you more patches continuing these 2 as I find them
while fixing other things.
Cheers,
Alex

Furthermore, let's normalize the messages, following membarrier.2 (because it's already quite extended), so that it's easy to use grep to find those pages. To find these pages, we used: $ grep -rn wrapper man? | sort -V and $ grep -rni support.*glibc | sort -V delete_module.2, init_module.2: glibc 2.23 is no longer maintained, so we changed the notes about wrappers, to say that there are no glibc wrappers for these system calls; see NOTES. We didn't fix some of the obsolete syscalls (create_module(2)), but if you prefer, we can fix those too.

That seems fine. > We didn't fix some of the obsolete syscalls (create_module(2)), > but if you prefer, we can fix those too. I think it's okay to leave it. The remainder of the patch looks good. The only reason that I'm not applying ir yet (and fixing the subject line myself) is that I wonder if the command I mentioned in response to the 0/2 mail might help you find other pages to include in the patch. Let me know.

Furthermore, let's normalize the messages, following membarrier.2 (because it's already quite extended), so that it's easy to use grep to find those pages. To find these pages, we used: $ grep -rn wrapper man? | sort -V and $ grep -rni support.*glibc | sort -V delete_module.2, init_module.2: glibc 2.23 is no longer maintained, so we changed the notes about wrappers, to say that there are no glibc wrappers for these system calls; see NOTES. We didn't fix some obsolete pages such as create_module.2.
