mips: hide regnum definitions behind _KERNEL/_WANT_MIPS_REGNUM

2019-08-22T21:43:21Z

machine/regnum.h ends up being included by sys/procfs.h and sys/ptrace.h via machine/reg.h. Many of the regnum definitions are too short and too generic to be exposing to any userland application including one of these two headers. Moreover, these actively cause build failures in googletest (template expanding to template ). Hide the definitions behind _KERNEL or _WANT_MIPS_REGNUM, and patch all of the userland consumers to define as needed.

lib: further adoption of SPDX licensing ID tags.

2017-11-26T02:00:33Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.

Preserve VFP state across signal delivery.

2017-03-26T08:36:56Z

We don't have enouch space to store full VFP context within mcontext stucture. Due to this: - follow i386/amd64 way and store VFP state outside of the mcontext_t but point to it. Use the size of VFP state structure as an 'magic' indicator of the saved VFP state presence. - teach set_mcontext() about this external storage. - for signal delivery, store VFP state to expanded 'struct sigframe'.

Cleanup structures related to VFP and/or mcontext_t.

2017-03-24T11:46:49Z

- in mcontext_t, rename newer used 'union __vfp' to equaly sized 'mc_spare'. Space allocated by 'union __vfp' is too small and cannot hold full VFP context. - move structures defined in fp.h to more appropriate headers. - remove all unused VFP structures. MFC after: 2 weeks
