Subject: [GIT PULL] LTO fix for v5.12-rc6

Hi Linus,

Please pull this LTO fix for v5.12-rc6. It seems that there is a bug in
ld.bfd when doing module section merging. As explicit merging is only
needed for LTO, the work-around is to only do it under LTO, leaving the
original section layout choices alone under normal builds.

Thanks!

-Kees
