Subject: [PATCH] powerpc/32: Curb objtool unannotated intra-function call warning
Date: Thu, 15 Dec 2022 17:22:58 +0530	[thread overview]
Message-ID: <20221215115258.80810-1-sv@linux.ibm.com> (raw)

objtool throws the following warning:
arch/powerpc/kexec/relocate_32.o: warning: objtool: .text+0x2bc: unannotated intra-function call

Fix this warning by annotating intra-function call, using
ANNOTATE_INTRA_FUNCTION_CALL macro, to indicate that the branch target
is valid.
