Apply the following automated changes to try to eliminate no-longer-needed sys/cdefs.h includes as well as now-empty blank lines in a row. Remove /^#if.*\n#endif.*\n#include\s+.*\n/ Remove /\n+#include\s+.*\n+#if.*\n#endif.*\n+/ Remove /\n+#if.*\n#endif.*\n+/ Remove /^#if.*\n#endif.*\n/ Remove /\n+#include\s+\n#include\s+/ Remove /\n+#include\s+\n#include\s+/ Remove /\n+#include\s+\n#include\s+/ Sponsored by: Netflix

spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch up to that fact and revert to their recommended match of BSD-2-Clause. Discussed with: pfg MFC After: 3 days Sponsored by: Netflix

arm: Add support for using VFP in kernel

2023-02-04T19:21:43Z

Add missing logic to allow in-kernel VFP usage for ARMv7 NEON. The implementation is strongly based on arm64 code. It introduces a family of fpu_kern_* functions to enable the usage of VFP instructions in kernel. Apart from that the existing armv7 VFP logic was modified, taking into account that the state of the VFP registers can now be modified in the kernel.

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.

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
