This copy of longlong.h is extremely dated and results in compile
errors on sparc32 when MPILIB is enabled, copy over the more uptodate
implementation from arch/sparc/math/sfp-util_32.h

Both sparc 32-bit's software divide assembler and MPILIB provide
clz_tab[] with identical contents.
Break it out into a seperate object file and select it when
SPARC32 or MPILIB is set.

Comment explains that existing clients do not call this function
with dsize == 0, which means that 1/0 should not happen.

Buggy client might pass zero nlimbs which is meaningless.
Added check for zero length.

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.

Definitely better to return error code than to divide by zero.

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.
