/proc/module: fix building without kallsyms
As reported by kernelci and other build bots, we now get a link failure without CONFIG_KALLSYMS: module.c:(.text+0xf2c): undefined reference to `kallsyms_show_value' This adds a dummy helper with the same name that can be used for compilation. It's not entirely clear to me what this should return for !CONFIG_KALLSYMS, I picked an unconditional 'false', which leads to the module address being unavailable to user space. Link: https://kernelci.org/build/mainline/branch/master/kernel/v4.14-5-g516fb7f2e73d/ Fixes: 516fb7f2e73d ("/proc/module: use the same logic as /proc/kallsyms for address exposure") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
