commit 8aa8eb2a8f5b3305a95f39957dd2b715fa668e21 upstream. Change objtool to support intra-function calls. On x86, an intra-function call is represented in objtool as a push onto the stack (of the return address), and a jump to the destination address. That way the stack information is correctly updated and the call flow is still accurate.
