Hi,

  I've been looking for a solution to my bcm4760 watchdog based restart
hook when I noticed that the kernel reboot/shutdown mechanism is having
a few unaddressed issues.

Those I identified are:

 1) context pointer often needed by the reset hook
    (currently local static data is used for this pourpose)
 2) unclear ownership/policy in case of multiple reset hooks
    (currently almost nobody seems to care much)

I'm not sure how this patchset solves (2); even with the new API, it's
still the case that whichever code calls set_machine_reset() last wins,
just like before where whichever code wrote to pm_power_off won. I'm not
sure what this series attempts to solve.
