sysctl: add register_sysctl() dummy helper
register_sysctl() has been around for five years with commit fea478d4101a ("sysctl: Add register_sysctl for normal sysctl users") but now that arm64 started using it, I ran into a compile error: arch/arm64/kernel/armv8_deprecated.c: In function 'register_insn_emulation_sysctl': arch/arm64/kernel/armv8_deprecated.c:257:2: error: implicit declaration of function 'register_sysctl' This adds a inline function like we already have for register_sysctl_paths() and register_sysctl_table(). Link: http://lkml.kernel.org/r/20171106133700.558647-1-arnd@arndb.de Fixes: 38b9aeb32fa7 ("arm64: Port deprecated instruction emulation to new sysctl interface") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Reviewed-by: Dave Martin <Dave.Martin@arm.com> Acked-by: Kees Cook <keescook@chromium.org> Acked-by: Will Deacon <will.deacon@arm.com> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: "Luis R.
