While preparing KASLR for s390, I stumbled over a section mismatch warning after enabling -fPIE compiler option: WARNING: vmlinux.o(.data+0x31070): Section mismatch in reference from the variable print_fmt_kfree_skb to the variable .init.data:ptp_filter.51760
I found a patch that would address this issue as part of a KASLR patch series for ARM from Ard Biesheuvel: https://marc.info/?l=kernel-hardening&m=150444052819798&w=2 https://marc.info/?l=kernel-hardening&m=150444051919794&w=2 That patch series did not make it upstream, and there seems to be no other arch using -fpic/pie so far, so this fix is still missing. Dave, could you please pick it up, as we will see this warning on s390 after my KASRL patches go upstream.
