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 warning has been fixed. This library is used to implemenet RSA digital signature verification used in IMA/EVM integrity protection subsystem.
