A general comment for all the patch descriptions: they should use imperative language, like: "move the implementation to the architecture-specific code." Also the subjects shouldn't have periods.

Also I think arch_create_orc() should have a more specific name anyway, maybe arch_orc_init(). So: arch_orc_init() arch_orc_create_sections() arch_orc_read_unwind_hints() -- Josh _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
