Hi Herbert

Back in March 2011, in preparation for EVM, Dmitry posted the GnuPG MPI
library patch here on linux-crypto. The reason given for not upstreaming
the MPI library, at the time, was for lack of an in kernel user
(http://www.mail-archive.com/linux-crypto@vger.kernel.org/msg05613.html).
With the recent merging of the EVM patches in linux-next, via
security-testing-2.6/#next, that is changing.  Any chance of re-opening
the discussion? 

thanks,

Mimi
