2012-02-02lib/mpi: removed unused functionsDmitry Kasatkin
do_encode_md() and mpi_get_keyid() are not parts of mpi library. They were used early versions of gnupg and in digsig project, but they are not used neither here nor there anymore.

2011-11-09crypto: GnuPG based MPI lib - additional sources (part 4)Dmitry Kasatkin
Adds the multi-precision-integer maths library which was originally taken from GnuPG and ported to the kernel by (among others) David Howells. This version is taken from Fedora kernel 2.6.32-71.14.1.el6. The difference is that checkpatch reported errors and warnings have been fixed. This library is used to implemenet RSA digital signature verification used in IMA/EVM integrity protection subsystem. Due to patch size limitation, the patch is divided into 4 parts. This code is unnecessary for RSA digital signature verification, but for completeness it is included here and can be compiled, if CONFIG_MPILIB_EXTRA is enabled.
