[ Upstream commit1e4d73d06c] The following build warning has been reported: arch/powerpc/crypto/ghashp8-ppc.o: warning: objtool: .text+0x22c: unannotated intra-function call This happens due to commitbb7f054f4d("objtool/powerpc: Add support for decoding all types of uncond branches") Disassembly of arch/powerpc/crypto/ghashp8-ppc.o shows: arch/powerpc/crypto/ghashp8-ppc.o: file format elf64-powerpcle Disassembly of section .text: 0000000000000140 <gcm_ghash_p8>: 140: f8 ff 00 3c lis r0,-8 ... 20c: 20 00 80 4e blr 210: 00 00 00 00 .long 0x0 214: 00 0c 14 00 .long 0x140c00 218: 00 00 04 00 .long 0x40000 21c: 00 00 00 00 .long 0x0 220: 47 48 41 53 rlwimi. r1,r26,9,1,3 224: 48 20 66 6f xoris r6,r27,8264 228: 72 20 50 6f xoris r16,r26,8306 22c: 77 65 72 49 bla 1726574 <gcm_ghash_p8+0x1726434> <== ...

But ghashp8-ppc.S is generated by a perl script and should have been marked as OBJECT_FILES_NON_STANDARD. Now that 'bla' is understood as a call instruction, that raw data is mis-interpreted as an infra-function call. Mark ghashp8-ppc.o as a OBJECT_FILES_NON_STANDARD to avoid this warning.
