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
