kernel/linux.git/lib/mpi/longlong.h, branch v3.18.3

alpha: Modernize lib/mpi/longlong.h

2013-07-19T20:54:23+00:00

Remove the compile warning for __udiv_qrnnd not having a prototype. Use the __builtin_alpha_umulh introduced in gcc 4.0. Reviewed-and-Tested-by: Matt Turner Signed-off-by: Matt Turner Signed-off-by: Richard Henderson

MPILIB: disable usage of floating point registers on parisc

2013-05-24T20:30:11+00:00

The umul_ppmm() macro for parisc uses the xmpyu assembler statement which does calculation via a floating point register. But usage of floating point registers inside the Linux kernel are not allowed and gcc will stop compilation due to the -mdisable-fpregs compiler option. Fix this by disabling the umul_ppmm() and udiv_qrnnd() macros. The mpilib will then use the generic built-in implementations instead. Signed-off-by: Helge Deller

MPI: Fix compilation on MIPS with GCC 4.4 and newer

2012-11-23T17:57:17+00:00

Since 4.4 GCC on MIPS no longer recognizes the "h" constraint, leading to this build failure: CC lib/mpi/generic_mpih-mul1.o lib/mpi/generic_mpih-mul1.c: In function 'mpihelp_mul_1': lib/mpi/generic_mpih-mul1.c:50:3: error: impossible constraint in 'asm' This patch updates MPI with the latest umul_ppm implementations for MIPS.

MPILIB: Provide count_leading/trailing_zeros() based on arch functions

2012-10-08T03:20:11+00:00

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.

lib: Fix 32-bit sparc udiv_qrnnd() definition in mpilib's longlong.h

2012-02-01T23:34:25+00:00

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 Reported-by: Al Viro Signed-off-by: David S. Miller Signed-off-by: James Morris

crypto: GnuPG based MPI lib - header files (part 2)

2011-11-09T09:45:26+00:00

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.
