Hello Randy,
Please checkout the following patch. Does it work?
----
x86: Fix kernel build in hw_nmi.c when CONFIG_HARDLOCKUP_DETECTOR=n.
This patch fixes kernel build introduced by commit
96a84c20d635fb1e98ab92f9fc517c4441f5c424. That commit supposed to
define touch_nmi_watchdog when CONFIG_HARDLOCKUP_DETECTOR=y in
hw_nmi.c. But mistakenly defines touch_nmi_watchdog when
CONFIG_HARDLOCKUP_DETECTOR=n in hw_nmi.c.
arch/x86/kernel/apic/hw_nmi.c:28: error: redefinition of ‘touch_nmi_watchdog’
include/linux/nmi.h:23: error: previous definition of
‘touch_nmi_watchdog’ was here
