This results in:

arch/powerpc/platforms/pseries/mobility.c: In function 'pseries_migrate_partition':
arch/powerpc/platforms/pseries/mobility.c:753:17: error: implicit declaration of function 'watchdog_hardlockup_set_timeout_pct'; did you mean 'watchdog_hardlockup_stop'? [-Werror=implicit-function-declaration]
  753 |                 watchdog_hardlockup_set_timeout_pct(factor);

with ppc64_defconfig -CONFIG_HARDLOCKUP_DETECTOR, because the dummy 
for watchdog_hardlockup_set_timeout_pct() is still defined in
arch/powerpc/include/asm/nmi.h which is no longer included.
