volk-2.5.0-bp154.1.44

- fixed build for s390x (no cpu_features)

- Update to version 2.5.0
  Kernels
  * volk_32f_stddev_and_mean_32f_x2: implemented Young and
    Cramer's algorithm
  * volk_32fc_accumulator_s32fc: Add new kernel
  * volk_16ic_x2_dot_prod_16ic_u_avx2: Fix Typo, was _axv2.
  * Remove _mm256_zeroupper() calls
  * Enforce consistent function prototypes
  * 32fc_index_max: Improve speed of AVX2 version
  * conv_k7_r2: Disable broken AVX2 code
  * improve volk_8i_s32f_convert_32f for ARM NEON
  * Calculate cos in AVX512F
  * Calculate sin using AVX512F
  Fixes:
  * Fix segmentation fault when using GCC 8
  * Fix python version detection
  * cmake: Check that 'distutils' is available
  * c11: Remove pre-C11 preprocessor instructions

- Update to version 2.4.1
  Build
  * cpu_features CMake option
  * Add cpu_features to static library build.
  * Use static liborc-0.4 library for static library build.
  * cmake: Detect if cpu_features submodule is present.
  Install
  * Check for lib64 versus lib and set LIB_SUFFIX accordingly.
- Switch back to the release github tarballs
- Verify source signature

- Update to version 2.4.0
  Documentation
  * Update README to be more verbose and to improve usefulness.
  CMake
  * Enable to not install volk_modtool.
  * Remove "find_package_handle_standard_args" warning.
  cpu_features
  * Use cpu_features v0.6.0 as a private submodule to detect
    available CPU features.
  * Fix incorrect feature detection for newer AVX versions.
  * Circumvent platform specific feature detection.
  * Enable more architecture specific kernels on more platforms.
  Kernels
  * Disable slow and broken SSE4.1 kernel in
    volk_32fc_x2_dot_prod_32fc.
  * Adjust min/max for 32f_s32f_convert_8i kernel
  * Use INT8_* instead of CHAR_*
- Upstream tarball does not have the cpu_features included so use
  a service file to generate the tarball.
- Add patch:
  * volk-fix-cpu_features-compilation-error.patch

- Update to version 2.3.0
  * Better reproducible builds
  * CMake improvements
    + ORC is removed from the public interface where it was never
    supposed to be.
    + CMake fixes for better usability
  * Enforce C/C++ coding style via clang-format
  * Kernel fixes
    + Add puppet for `power_spectral_density` kernel
    + Treat the `mod_range` puppet as a puppet for correct use
    with `volk_profile`
    + Fix `index_max` kernels
    + Fix `rotator`. We hope that we finally found the root cause
    of the issue.
  * Kernel optimizations
    + Updated log10 calcs to use faster log2 approach
    + Optimize `complexmultiplyconjugate`
  * New kernels
    + accurate exp kernel is finally merged after years
    + Add 32f_s32f_add_32f kernel to perform vector + scalar float
    operation

- Update to version 2.2.1
  Changes
  * Fix loop bound in AVX rotator
  * Fix out-of-bounds read in AVX2 square dist kernel
  * Fix length checks in AVX2 index max kernels
  * includes: rearrange attributes to simplify macros Whitespace
  * kernels: fix usage in header comments
- Update to version 2.2.0
  Highlights
  * Dropped Python 2 build support
    + Removed Python six module dependency
  * Use C11 aligned_alloc whenever possible
  * Add VOLK version in volk_version.h (included in volk.h)
  * Improved CMake code
  * Improved code with lots of refactoring and performance tweaks

- Update to version 2.1.0
  * The AVX FMA rotator bug is fixed
  * VOLK offers `volk::vector<>` for C++ to follow RAII
  * Move towards modern dependencies
  - CMake 3.8
  - Prefer Python3
  - We will drop Python2 support in a future release!
  - Use C++17 `std::filesystem`
  - This enables VOLK to be built without Boost if
    available!
  * more stable CI
  * lots of bugfixes
  * more optimized kernels, especially more NEON versions

- First version of standalone VOLK package, version 2.0.0
