Ken Chen [Mon, 8 Aug 2005 22:25:00 +0000 (15:25 -0700)]
this changeset broke the "nohalt" kernel boot option.
  8df5a500a3e97f7811cdce0f553ca1917ccd4220

default_idle() is looking at new variable can_do_pal_halt.  However,
that variable did not get cleared upon "nohalt" boot option.  Result
is that "nohalt" option is ignored until perfmon is exercised.
