When livepatch tries to patch a function it takes the function address and asks ftrace to install the livepatch handler at that location. ftrace will look for an mcount call site at that exact address. On powerpc the mcount location is not the first instruction of the function, and in fact it's not at a constant offset from the start of the function. To accommodate this add a hook which arch code can override to customise the behaviour.
