2015-04-17tile: ftrace: fix function_graph tracer issuesTony Lu
- 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.

2010-06-04arch/tile: core support for Tilera 32-bit chips.Chris Metcalf
This change is the core kernel support for TILEPro and TILE64 chips. No driver support (except the console driver) is included yet. This includes the relevant Linux headers in asm/; the low-level low-level "Tile architecture" headers in arch/, which are shared with the hypervisor, etc., and are build-system agnostic; and the relevant hypervisor headers in hv/.
