Subject: [PATCH AUTOSEL 3.18 2/4] RISC-V: include linux/ftrace.h in asm-prototypes.h
Date: Mon, 8 Oct 2018 11:27:47 -0400 [thread overview]
Message-ID: <20181008152749.71018-2-sashal@kernel.org> (raw)
In-Reply-To: <20181008152749.71018-1-sashal@kernel.org>
From: James Cowgill <jcowgill@debian.org>
[ Upstream commit 57a489786de9ec37d6e25ef1305dc337047f0236 ]
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.
