Headscratch -- the Kconfig should have HMAC selected for compilation. When 
HMAC is available (regardless whether it is a module or not), it is pulled in 
by the kernel crypto API. Thus, there should not have been the error that HMAC 
is missing.

Can you send your .config file, please?

Ciao
Stephan
