On: Potential Impact of Spectre on Processors in the Power family

[carey]

I'm more interested in the non-PASE (more accurately, non-Teraspace) situation. The single level store maps every program into the same address space. Will POWER speculatively access another user's data before it discovers that the pointer is invalid or the array index is out of range?

Yes, it is an interesting case, I hope we get more detail than this paper soon.
