Subject: powerpc/32: Curb objtool unannotated intra-function call warning
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6035e7e35482653d6d93f35f01e1a320573d58f0;p=linux.git

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

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.
