Subject: [PATCH 0/5] Improve watchdog config for arch watchdogs

Hi Don,

These first 4 patches are a further progression of my effort
to make some of the hard lockup watchdog framework usable by
arch code NMI watchdog.

The last patch is a powerpc-specific implementation for
reference to see how I'm using the changes.

Thanks,
Nick

Nicholas Piggin (5):
  watchdog: remove unused declaration
  watchdog: introduce arch_touch_nmi_watchdog()
  watchdog: split up config options
  watchdog: provide watchdog_reconfigure() for arch watchdogs
  powerpc/64s: SMP hardlockup watchdog
