Subject: hexagon: vmlinux.lds.S: handle attributes section
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=549aa9678a0b3981d4821bf244579d9937650562;p=linux.git

hexagon: vmlinux.lds.S: handle attributes section

After the linked LLVM change, the build fails with
CONFIG_LD_ORPHAN_WARN_LEVEL="error", which happens with allmodconfig:

  ld.lld: error: vmlinux.a(init/main.o):(.hexagon.attributes) is being placed in '.hexagon.attributes'

Handle the attributes section in a similar manner as arm and riscv by
adding it after the primary ELF_DETAILS grouping in vmlinux.lds.S, which
fixes the error.
