m32r allmodconfig build was failing with the error: ERROR: "smp_flush_cache_all" [drivers/misc/lkdtm.ko] undefined!
lkdtm driver at drivers/misc is using flush_icache_range() which for m32r is defined as smp_flush_cache_all() if CONFIG_SMP is defined. But as smp_flush_cache_all() was not exported so the build was failing with the error of undefined symbol.

Hi Andrew, as usual sending the patch to you as m32r arch is orphan. build log is at: https://travis-ci.org/sudipm-mukherjee/parport/jobs/132180911
