Various pieces of code around the kernel want to be able to trigger an
orderly poweroff. This pulls them together into a single
implementation.
By default the poweroff command is /sbin/poweroff, but it can be set
via sysctl: kernel/poweroff_cmd. This is split at whitespace, so it
can include command-line arguments.
This patch replaces four other instances of invoking either "poweroff"
or "shutdown -h now": one sparc64, two sbus drivers, and acpi thermal
management.

I'm not sure how this ended up in the x86 tree
(ftp://ftp.firstfloor.org/pub/ak/x86_64/quilt/patches/add-common-orderly_poweroff),
but recent changes in arch/sparc64/kernel/power.c have broken it.
I just sent the same mail to Dave - sorry, forgot to cc: you. It's
there because I added it as a prereq for Xen. I'm planning on
submitting it later today, ideally once we've sorted this out.
