Since the purpose of the macro is to print the BUGCHECK info, make this config option depend on PRINTK. Fixes multiple occurrences of this build error: ../include/linux/printk.h:208:5: error: static declaration of '_printk' follows non-static declaration 208 | int _printk(const char *s, ...) | ^~~~~~~ In file included from ../arch/ia64/include/asm/cmpxchg.h:5, ../arch/ia64/include/uapi/asm/cmpxchg.h:146:28: note: previous declaration of '_printk' with type 'int(const char *, ...)' 146 | extern int _printk(const char *fmt, ...); Cc: linux-ia64@vger.kernel.org Cc: Andrew Morton Cc: Tony Luck Cc: Chris Down Cc: Paul Gortmaker Cc: John Paul Adrian Glaubitz Signed-off-by: Randy Dunlap Signed-off-by: Petr Mladek Signed-off-by: Sasha Levin --- arch/ia64/Kconfig.debug | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/ia64/Kconfig.debug b/arch/ia64/Kconfig.debug index de9d507ba0fd4..ee6c7f75f479d 100644 --- a/arch/ia64/Kconfig.debug +++ b/arch/ia64/Kconfig.debug @@ -41,7 +41,7 @@ config DISABLE_VHPT config IA64_DEBUG_CMPXCHG bool "Turn on compare-and-exchange bug checking (slow!)" - depends on DEBUG_KERNEL + depends on DEBUG_KERNEL && PRINTK help Selecting this option turns on bug checking for the IA-64 compare-and-exchange instructions.
