Subject: powerpc: Include .BTF section
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=cb0cc635c7a9fa8a3a0f75d4d896721819c63add;p=linux.git

powerpc: Include .BTF section

Selecting CONFIG_DEBUG_INFO_BTF results in the below warning from ld:
  ld: warning: orphan section `.BTF' from `.btf.vmlinux.bin.o' being placed in section `.BTF'

Include .BTF section in vmlinux explicitly to fix the same.
