• aacf29bf1   MPILIB: Provide count_leading/trailing_zeros() based on arch functions ... Browse Code »

  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.

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

• cdec9cb51   crypto: GnuPG based MPI lib - source files (part 1) ... Browse Code »

  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.
