I forgot to base this on 5c20a3a9df19 ("RISC-V: Fix compilation without 
RISCV_ISA_ZICBOM"), which I keep forgetting about because it went in 
without an Ack (which has made through a bunch of headaches).

I'm rewriting my for-next since this was merged pretty recently, so with 
any luck I got that right.  It's on for-next now.
