Hmm... This won't actually work for machine check wakeups either.

We're doing the low level machine check before checking for wakeup,
which complicates things a little bit.

Simplest way to handle that might be to just always immediately
call the restore paca function at machine check entry, and then
just always mark machine checks as not-recoverable for DD1.

Thanks,
Nick
