linux-toradex.git/lib/mpi/mpi-pow.c, branch v3.12.50 Linux kernel for Apalis and Colibri modules MPILIB: Provide count_leading/trailing_zeros() based on arch functions 2012-10-08T03:20:11+00:00 David Howells dhowells@redhat.com 2012-09-13T12:09:33+00:00 aacf29bf1bf133f6219e6f8969d4ebc2ac76458f Provide count_leading/trailing_zeros() macros based on extant arch bit scanning functions rather than reimplementing from scratch in MPILIB. Whilst we're at it, turn count_foo_zeros(n, x) into n = count_foo_zeros(x). Also move the definition to asm-generic as other people may be interested in using it.

Provide count_leading/trailing_zeros() macros based on extant arch bit scanning
functions rather than reimplementing from scratch in MPILIB.

Whilst we're at it, turn count_foo_zeros(n, x) into n = count_foo_zeros(x).

Also move the definition to asm-generic as other people may be interested in
using it.

crypto: GnuPG based MPI lib - source files (part 1) 2011-11-09T09:45:22+00:00 Dmitry Kasatkin dmitry.kasatkin@intel.com 2011-08-31T11:05:16+00:00 cdec9cb5167ab1113ba9c58e395f664d9d3f9acb 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.
