Hi Anton,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on powerpc/next]
[also build test ERROR on v4.19-rc5 next-20180928]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system]

If CONFIG_PPC_WATCHDOG is enabled, we always cap the decrementer to
0x7fff. As suggested by Nick, add a run time check of the watchdog
cpumask, so if it is disabled we use the large decrementer.
