h8300, ia64, and sh64 still have possible outstanding issues,

would be nice to get these looked at.
+ia64 - is safe_halt call racy vs interrupts? (does it sleep?) (See #4a)
safe_halt() makes a call to PAL[1] to go to a lower power state. It does
not do anything that would require a sleep.
So it won't need an interrupt to be revived out of that state?
Thank you Tony, I'll take ia64 off the list.
The other change I made to ia64 is to use TIF_POLLING_NRFLAG to
inhibit wakeup IPIs to idle threads - is this something that
looks acceptable?
Clearing TIF_POLLING_NRFLAG from around safe_halt() in my patch
is superfluous if safe_halt doesn't require an interrupt to wake
up - I'll remove that hunk.
Thanks,
Nick
