Subject: [PATCH 3/3] arch: unicore32: ksyms: export '__cpuc_coherent_kern_range'
 to avoid compiling failure

flush_icache_range() is '__cpuc_coherent_kern_range' under unicore32,
and lkdtm.ko needs it. At present, '__cpuc_coherent_kern_range' is
still used by unicore32, so export it to avoid compiling failure.

The related error (with allmodconfig under unicore32):

  ERROR: "__cpuc_coherent_kern_range" [drivers/misc/lkdtm.ko] undefined!
