The following build warning have been reported:

   arch/powerpc/kvm/book3s_hv_rmhandlers.o: warning: objtool: .text+0xe84: intra_function_call not a direct call
   arch/powerpc/kernel/switch.o: warning: objtool: .text+0x4: intra_function_call not a direct call

This happens due to commit bb7f054f4de2 ("objtool/powerpc: Add support
for decoding all types of uncond branches") because that commit decodes
'bl .+4' as a normal instruction because that instruction is used by
clang instead of 'bcl 20,31,+.4' for relocatable code.

The solution is simply to remove the ANNOTATE_INTRA_FUNCTION_CALL
annotation now that the instruction is not seen as a function call
anymore.
