The answer should be yes.

In the branch referenced by Will's pull request, I've integrated a contribution
from Nico which supplies the missing flush function anyway ... so the combined
patch ought to fix that problem anyway:

+/*
+ *     flush_icache_all()
+ *
+ *     Unconditionally clean and invalidate the entire icache.
+ */
+ENTRY(mohawk_flush_icache_all)
+       mov     r0, #0
+       mcr     p15, 0, r0, c7, c5, 0           @ invalidate I cache
+       mov     pc, lr
+ENDPROC(mohawk_flush_icache_all)

Cheers
