I received this one also before. But that seems to be an error on the OpenRISC
platform as the random_get_entropy() function or the get_cycles function is
not implemented as defined.
The crypto code uses the following which triggers the issue:
__u64 tmp = 0;
tmp = random_get_entropy();
That one seems to be an appropriate use of random_get_entropy() which on
almost all arches is an alias for get_cycles().
