* tile: ftrace: fix function_graph tracer issuesTony Lu2015-04-171-0/+2
| | | | | | | | | | | - 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.

* arch/tile: core support for Tilera 32-bit chips.Chris Metcalf2010-06-041-0/+20
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/.
