The HAVE_ prefix means that the code could be enabled. Add another variable for HAVE_HARDLOCKUP_DETECTOR_SPARC64 without this prefix. It will be set when it should be built. It will make it compatible with the other hardlockup detectors. Before, it is far from obvious that the SPARC64 variant is actually used: $> make ARCH=sparc64 defconfig $> grep HARDLOCKUP_DETECTOR .config CONFIG_HAVE_HARDLOCKUP_DETECTOR_BUDDY=y CONFIG_HAVE_HARDLOCKUP_DETECTOR_SPARC64=y After, it is more clear: $> make ARCH=sparc64 defconfig $> grep HARDLOCKUP_DETECTOR .config CONFIG_HAVE_HARDLOCKUP_DETECTOR_BUDDY=y CONFIG_HAVE_HARDLOCKUP_DETECTOR_SPARC64=y CONFIG_HARDLOCKUP_DETECTOR_SPARC64=y Link: https://lkml.kernel.org/r/20230616150618.6073-6-pmladek@suse.com Signed-off-by: Petr Mladek <pmladek@suse.com> Reviewed-by: Douglas Anderson <dianders@chromium.org> Cc: Christophe Leroy <christophe.leroy@csgroup.eu> Cc: "David S.

Sparc64 hardlockup detector is the last one developed before adding
|
|
the common infrastructure for handling hardlockup detectors. It is
|
|
always built. It does _not_ use the common command line parameters
|
|
and sysctl interface, except for /proc/sys/kernel/nmi_watchdog.
