  minor changes in the way the data is stored this is to support the
  abstraction of an optional secure memory allocation which may be
  used to avoid revealing of sensitive data due to paging etc the gnu
  mp library itself is published under the lgpl however i decided to

MPI headers contain definitions for huge number of non-existing
functions.

Most part of these functions was removed in 2012 by Dmitry Kasatkin
 - 7cf4206a ("Remove unused code from MPI library")
 - 9e235dca ("Revert "crypto: GnuPG based MPI lib - additional ...")
 - bc95eead ("lib/mpi: removed unused functions")
however headers wwere not updated properly.

Also I deleted some unused macros.

When we use CONFIG_PROFILE_ALL_BRANCHES, every 'if()' introduces
a static variable, but that is not allowed in 'extern inline'
functions:

mpi-inline.h:116:204: warning: '______f' is static but declared in inline function 'mpihelp_sub' which is not static
mpi-inline.h:113:184: warning: '______f' is static but declared in inline function 'mpihelp_sub' which is not static
mpi-inline.h:70:184: warning: '______f' is static but declared in inline function 'mpihelp_add' which is not static
mpi-inline.h:56:204: warning: '______f' is static but declared in inline function 'mpihelp_add_1' which is not static

This changes the MPI code to use 'static inline' instead, to get
rid of hundreds of warnings.

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.
