Ard Biesheuvel (8):
  ARM: ftrace: ensure that ADR take Thumb bit into account
  ARM: ftrace: use ADD not POP to counter PUSH at entry
  ARM: ftrace: use trampolines to keep .init.text in branching range
  ARM: ftrace: avoid redundant loads or clobbering IP
  ARM: ftrace: avoid unnecessary literal loads
  ARM: ftrace: enable HAVE_FUNCTION_GRAPH_FP_TEST
  ARM: unwind: track location of LR value in stack frame
  ARM: ftrace: enable the graph tracer with the EABI unwinder
