EVT0 is for emulation, EVT1 is for reset, and EVT4 is the "global int
disable" region.  None of these are used by software (or even hardware),
so don't bother saving/restoring them when we hibernate since nothing
ever uses these in Linux (the only thing they would be useful for is
core-memory scratch, but that's just crazy talk).
