[PATCH 0/7] Build ppc64le kernel using ABIv2, supplemental patches

[Anton Blanchard]

These patches apply against my last series and fix all known
ABIv2 issues.

To stress the module loader and dynamic ftrace code, I built an
allmodconfig kernel and inserted every module I could. I found a bunch
of bugs in the modules themselves, but in the end I managed to
get quite a few modules to load:

# cat /proc/modules | wc -l
3830

It survived a fair bit of poking (enabling/disabling function tracers
etc).

Anton Blanchard (7):
  powerpc: Add _GLOBAL_TOC for ABIv2 assembly functions exported to
    modules
  powerpc: ftrace_caller, _mcount is exported to modules so needs
    _GLOBAL_TOC()
  powerpc/kprobes: Fix ABIv2 issues with kprobe_lookup_name
  powerpc/modules: Create is_module_trampoline()
  powerpc/modules: Create module_trampoline_target()
  powerpc/ftrace: Use module loader helpers to parse trampolines
  powerpc/ftrace: Fix ABIv2 issues with __ftrace_make_call
