Major changes since v3:
  * the graph tracer works now.
    It turned out the stack frame it tried to manipulate does not
    exist at that point.
  * changes only needed in order to support -mprofile-kernel are now
    in a separate patch, prepended.
  * Kconfig cleanup so this is only selectable on ppc64le.

Torsten Duwe (9):
  ppc64 (le): prepare for -mprofile-kernel
  ppc64le FTRACE_WITH_REGS implementation
  ppc use ftrace_modify_all_code default
  ppc64 ftrace_with_regs configuration variables
  ppc64 ftrace_with_regs: spare early boot and low level
  ppc64 ftrace: disable profiling for some functions
  ppc64 ftrace: disable profiling for some files
  Implement kernel live patching for ppc64le (ABIv2)
  Enable LIVEPATCH to be configured on ppc64le and add livepatch.o if it
    is selected.
