From 57a489786de9ec37d6e25ef1305dc337047f0236 Mon Sep 17 00:00:00 2001 From: James Cowgill Date: Thu, 6 Sep 2018 22:57:56 +0100 Subject: RISC-V: include linux/ftrace.h in asm-prototypes.h Building a riscv kernel with CONFIG_FUNCTION_TRACER and CONFIG_MODVERSIONS enabled results in these two warnings: MODPOST vmlinux.o WARNING: EXPORT symbol "return_to_handler" [vmlinux] version generation failed, symbol will not be versioned. WARNING: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned. When exporting symbols from an assembly file, the MODVERSIONS code requires their prototypes to be defined in asm-prototypes.h (see scripts/Makefile.build). Since both of these symbols have prototypes defined in linux/ftrace.h, include this header from RISC-V's asm-prototypes.h.
