[PATCH] powerpc/32: Curb objtool unannotated intra-function call warning

From: Sathvika Vasireddy
Date: Thu Dec 15 2022 - 06:53:55 EST


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.
