SLC write in OpenCL?

Is there any way to do a SLC write in OpenCL, or force a L2 cache line flush after a write?  I'm doing writes that I know won't be read back for a long time, so I don't want them polluting the L2.

I've tried volatile pointers and write_mem_fence, both of which just add

s_waitcnt vmcnt(0)

after the writes.
