Subjectlinux-next: build failure after merge of the akpm-current tree
Hi Andrew,

After merging the akpm-current tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

arch/powerpc/kernel/setup_64.c: In function 'disable_hardlockup_detector':
arch/powerpc/kernel/setup_64.c:796:2: error: implicit declaration of function 'watchdog_enable_hardlockup_detector' [-Werror=implicit-function-declaration]
watchdog_enable_hardlockup_detector(false);
^

Caused by commit 069bb95b9e38 ("watchdog: introduce the
hardlockup_detector_disable() function") interacting with commit
c54b2bf1b5e9 ("powerpc: Add ppc64 hard lockup detector support") from
the powerpc-mpe tree.

I applied the following merge fix patch (hopefully that is all that is
required):
