I did some more testing, including toggling /sys/kernel/debug/powerpc/count_cache_flush and checking the code in xmon before:
c00000000000db58 7ee00026 mfcr r23
c00000000000db5c fae101a0 std r23,416(r1)
c00000000000db60 f8230000 std r1,0(r3)
c00000000000db64 4bffdb1d bl c00000000000b680 # flush_count_cache+0x0/0x2480

and after:
c00000000000db58 7ee00026 mfcr r23
c00000000000db5c fae101a0 std r23,416(r1)
c00000000000db60 f8230000 std r1,0(r3)
c00000000000db64 60000000 nop

All looks correct. Thanks for flipping the tag, I think it looks good. I'll run some regression on it now, too.
