Is "clflush" instruction Intel CAT-agnostic?

On a processor that supports L3 CAT (Cache Allocation Technology), assume I create two partitions (P1 and P2). However, I run the instruction "clflush" on an address which should reside in P1 but after switching from P1 to P2. Will "clflush" evict the cache-line in P1 or not?
