This series applies on top of the series v3 "objtool: Enable and implement --mcount option on powerpc" [1] rebased on powerpc-next branch
A few modifications are done to core parts to enable powerpc implementation: - R_X86_64_PC32 is abstracted to R_REL32 so that it can then be redefined as R_PPC_REL32. - A call to static_call_init() is added to start_kernel() to avoid every architecture to have to call it - Trampoline address is provided to arch_static_call_transform() even when setting a site to fallback on a call to the trampoline when the target is too far.
