Probably any other dump mechanism should be aware of bad HW pages as well,
so we might be better off to add a flag right away. While we are at it I
would propose to have actually two flags :
- hard error (which will cause a MCA and should be skipped when taking
a system dump)
- soft error (page has encountered SBE, so we might want to avoid future
allocation, but it can be dumped without causing an MCA)
Then we need to define some API that this information can be saved accross
a reboot, so we don't have to have another process hitting the UCE to find
out that there really is a problem at that location
