With the introduction of llvm14, the powerpc* loader used on ofw/pseries for 32 and 64 bit architectures puts the .data.rel.ro section after .data section. This caused a crash kernel didn't boot. Bisect pointed to change https://reviews.llvm.org/D111717 but problem could be fixed by adding a section description to make it appear in the expected order. This patch is based on discussion at: https://github.com/llvm/llvm-project/issues/56306 MFC after: 1 day Sponsored by: Instituto de Pesquisas Eldorado (eldorado.org.br)
