- Two, the Generic Error Data Entry (aka UEFI Section Descriptor) has a

This one sounds to make sense ... the flag description sounds exactly what
we want - I won't feel embarrassed explaining to people why Linux takes
action when it sees a record like this.
Yep, and firmware can set that flag when it wants to, so decision when
to offline a page is left to the platform.
Ok, I will work towards a patch which does this.
Thanks,
