#     
#     Pull LTO fix from Kees Cook:
#      "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:
#     
#        - Only perform explicit module section merges under LTO (Sean
#          Christopherson)"
#     
#     * tag 'lto-v5.12-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
#       kbuild: lto: Merge module sections if and only if CONFIG_LTO_CLANG is enabled
