The cache system isn't aware of threads or processes, but it's clearly aware of address spaces.
No, it's definitely not aware of address spaces. Caching is based on the physical address.
In fact, it's based on the low-order bits of the physical address. So, things that are in different physical pages but have the same lower-order bits can conflict.
