This patch adds the necessary "hook" to allow SGI/SN
machines to perform a system power off upon a
'init 0', 'halt -p', 'poweroff' or 'shutdown -h'.
The "hook" is to set the pm_power_off callback
to ia64_sn_power_down(). pm_power_off is checked
in machine_power_off()/do_poweroff() and, if set, is executed.
ia64_sn_power_down() is a function already present (but not
used currently) in the sn kernel.
ia64_sn_power_down() makes a SAL call to execute the
power off.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
