linux-toradex.git/arch/tile/kernel/mcount_64.S, branch v4.2.7 Linux kernel for Apalis and Colibri modules tile: ftrace: fix function_graph tracer issues 2015-04-17T18:01:38+00:00 Tony Lu zlu@ezchip.com 2015-03-27T18:46:38+00:00 437d3e124d25daaa671bfecfd4015ecd2503a955 - Add support for ARCH_SUPPORTS_FTRACE_OPS - Replace the instruction in ftrace_call with the bundle {move r10, lr; jal ftrace_stub}, so that the lr contains the right value after returning from ftrace_stub. An alternative fix might be to leave the instruction in ftrace_call alone when it is being updated with ftrace_stub.
