- remove the old LGPL license headers from all files in Spack
- add SPDX headers to all files
- core and most packages are (Apache-2.0 OR MIT)
- a very small number of remaining packages are LGPL-2.1-only
* kokkos: update kokkos spackage to add current host/gpu architectures.
* kokkos: simplify host/gpu architecture selection and make intent of arg population logic more clear.
* kokkos: mollify flake8.
* Make strings and logic more pythonic. Add error for GPU arch without CUDA.
* kokkos: simplify conflicts behaviour. make args population more pythonic.
* kokkos: move gpu values to list for use in variant and conflicts checking.
* kokkos: How fortunate the man with None.
* kokkos: fix gpu_arch conflict loop error. add conflict to guard against +cuda and 2.5.00:develop versions, until kokkos issue #1296 is resolved.
* kokkos: mollify flake8.
* kokkos: add descriptive message to version conflict with +cuda.
Added OpenMP variant for kokkos that can be disabled to build and test
on platforms where OpenMP is not available or desired. Also updated
version list
* Current versions of kokkos conflict with hwloc 2.x
Current versions of kokkos cannot build with hwloc v2.x due to changes
in the associated structs. Requiring v1.11.9 for the time being
until it becomes clear what the kokkos model will be
* Explicitly commenting fix for posterity
Explicitly commented version number of hwloc dependency for kokkos for
posterity purposes and to pass code coverage for speedy merging
* Generalized Kokkos's Hwloc Dependency
Generalized dependency to v1.x of hwloc
* Fixed Flake8 issue
Fixed comment to conform to flake8
* Fixed ordering for Version Requirements
Fixed ordering to indicate <= 1.11.9, not >1
* Generalized kokkos dependency
